# Alerting and Notification Routing

Treat Grafana Alerting as one end-to-end path. A syntactically valid rule or a firing instance does not prove that the intended responder receives or resolves a notification.

## Model the path

Trace:

```text
data-source query -> expressions -> condition -> rule evaluation
-> alert instances and labels -> direct contact point or policy tree
-> grouping and timing -> silence/mute evaluation -> receiver integration
-> firing delivery -> recovery -> resolved delivery
```

Record Grafana version/edition, organization, rule provenance, rule group and interval, data-source UID, labels, annotations, policy owner, contact point, and authorized test route.

## Rule design

- Define the user-visible symptom, owner, service scope, severity rationale, and required action before writing the rule.
- Prefer symptom-based paging. Route infrastructure or diagnostic signals to a lower-interruption channel unless policy says otherwise. Use `site-reliability-engineering` for page-worthiness and SLO/burn-rate design.
- Validate every query and expression with representative data. Confirm units, reduction, thresholds, evaluation range, delay, and data-source availability.
- Decide `noDataState`, execution-error state, pending period, and keep-firing/recovery behavior deliberately. Defaults are not a reliability policy.
- Multi-dimensional rules create one instance per retained label set. Keep only dimensions that change routing or action, and bound instance cardinality.
- Add concise summary/description, owner, severity, dashboard/panel link, and runbook link. Labels route and group; annotations explain.
- Review duplicate coverage, flapping risk, downstream cascades, and maintenance behavior before enabling.

## Routing semantics

Grafana uses one notification-policy tree by default. The public-preview `alertingMultiplePolicies` feature flag can enable multiple independently managed routing trees. Discover the feature-flag state, selected tree, and Alertmanager before tracing a route. For the exact firing labels, inspect:

1. root receiver and inherited grouping/timing;
2. child matcher order, deepest matching child, and whether matching continues to siblings;
3. contact point and integration settings, with secrets redacted;
4. group-by labels, group wait, group interval, and repeat interval;
5. active or mute intervals and their time zones;
6. silences and matchers;
7. default-route fallback and unmatched labels;
8. direct contact-point selection on rules, which creates internal routing outside the user-managed policy tree;
9. external receiver-side deduplication or escalation.

Routing descends recursively through matching children. By default, only the deepest matching child handles the instance and sibling evaluation stops after a match; enabling continuation allows subsequent siblings to handle it too. Contact point, grouping, and general timing can be inherited from parents, while mute timings must be configured at each applicable level.

Preserve existing routing and escalation unless the requested scope explicitly changes them. A policy-tree provisioning operation can replace that complete user-managed tree, but it does not replace internal policies created when rules directly select contact points. Diff every affected tree and direct-contact-point route, not only the desired branch.

## Silences and mute timings

- Silences are one-time matcher-based suppression; mute timings are recurring intervals.
- They pause notifications, not rule evaluation.
- Scope matchers narrowly and record owner, reason, start/end or recurrence, time zone, and expiry/review.
- Verify that unrelated alerts still route. Never use a broad silence as a substitute for fixing a noisy rule.

## Safe testing

Sending a notification is an external mutation. Before testing, confirm receiver, audience, expected message volume, maintenance window, and cleanup.

Preferred sequence:

1. Inspect rule, query result, current instances, labels, and policy tree without delivery.
2. Use a designated test rule/contact point or non-paging receiver.
3. Exercise normal to pending to firing behavior with a controlled signal where supported.
4. Confirm the effective route and grouped firing notification.
5. Remove the condition and confirm recovery plus resolved notification when enabled.
6. Check duplicate notifications, timing, templates, links, and secret redaction.
7. Restore the test signal and remove temporary test resources through their owner.

If production injection or receiver delivery is not authorized, stop at route simulation/inspection and report the gap.

## Provisioning and API cautions

- File-provisioned alerting resources are not editable in the UI and are unavailable in Grafana Cloud.
- Importing an existing alerting resource can conflict; reconcile ownership before import.
- API object formats and export/file-provisioning formats differ. Export JSON is not necessarily valid as an API update body.
- Provenance controls editability. Do not disable provenance merely to bypass the source-of-truth model.
- Legacy alert provisioning endpoints and App Platform APIs have resource-specific deprecation and maturity. Read current schemas for the target version.
- Contact points, policies, templates, and mute timings can expose secrets. Do not request decryption for routine export or evidence.

## Diagnosis

| Symptom | Evidence chain |
|---|---|
| Rule never evaluates | scheduler/rule-group state -> pause state -> query execution -> data-source auth -> expression/condition |
| Rule stays Normal | raw data -> time range -> reduction -> threshold -> pending period -> label instances |
| Rule is Error/No Data | query inspector/evaluation error -> source availability -> no-data/error policy |
| Firing but no notification | actual labels -> policy path -> silence/mute -> grouping timers -> contact point test -> receiver logs |
| Wrong team notified | matcher set/order -> inherited receiver -> continue behavior -> default route -> external escalation |
| Firing repeats/noise | instance cardinality -> flapping -> group labels/timers -> repeat interval -> duplicate rules/routes |
| No resolved message | recovery state -> keep-firing behavior -> disable-resolve setting -> grouping -> receiver delivery |

## Completion

Report separately whether query semantics, rule state transitions, policy matching, firing delivery, and resolved delivery were verified. Never collapse them into one "alert works" claim.

# API and Version Discovery

Read this before selecting an API, schema, or command. Grafana product, edition, and API surfaces evolve independently.

## Establish the target

Record:

1. Exact version and commit from `/api/health`, the server binary, package, image, or Cloud stack metadata.
2. OSS, Enterprise, or Cloud. Do not infer Enterprise capabilities from an Enterprise image name alone; verify licensed behavior where relevant.
3. Deployment owner: package, Docker/Compose, Helm, Operator, or Cloud.
4. Organization and folder context. Service accounts are organization-scoped; server administration is a different authority.
5. Authentication: interactive user, service account, identity provider, auth proxy, or Cloud access policy. Grafana API service accounts are not telemetry-ingestion credentials.
6. Existing resource provenance and the authorized read/write scope.

## API generations

- Grafana 12 introduced versioned Kubernetes-style APIs under `/apis`.
- Starting with Grafana 13, legacy `/api` routes are deprecated but remain operational for now.
- Migration is incomplete. Some legacy resources have no exact `/apis` equivalent, and some APIs have distinct versions or maturity levels.
- Dashboard APIs under `/apis/dashboard.grafana.app/...` require Grafana 12 or later. Consult the target's current Swagger because documentation examples may lag the newest API version.
- Alerting migration is resource-specific. Rules, recording rules, receivers, policy resources, templates, and time intervals can have different App Platform groups and versions.

Do not convert paths mechanically. For each operation, confirm the target version, documented endpoint, method, schema, namespace, concurrency/version field, required permissions, and response format.

## Read-only API procedure

1. Call `/api/health` without credentials only to establish reachable server/database metadata. It is not a provisioning or data-source test.
2. Use a least-privilege service account for organization-scoped reads. Prefer short-lived tokens and protected environment injection.
3. Query one bounded collection or UID at a time. Honor pagination and continuation tokens.
4. Record status, selected non-secret fields, and request scope. Do not retain full responses when they contain queries, annotations, receiver settings, user details, or secure metadata.
5. A `401` proves authentication was required, not whether the route exists. A `403` proves the authenticated identity lacked permission, not that the resource is absent.
6. A `404` can mean an absent object, unsupported route, wrong namespace, wrong organization, or proxy rewriting. Reconcile with version and server logs before concluding.

## Authorization scopes

Treat these separately:

| Scope | Typical resources |
|---|---|
| Server administration | global users, organizations, settings, licensing |
| Organization administration | data sources, teams, service accounts, plugins, organization settings |
| Folder/dashboard | folders, dashboards, library panels, annotations, permissions |
| Alerting | rules, groups, receivers/contact points, policies, templates, silences, mute timings |
| Data-source query | arbitrary queries allowed by the data source and Grafana permission model |

Grafana server administrator and organization administrator are distinct. In Grafana Cloud there is no server administrator role. Enterprise and Cloud add resource-level RBAC and data-source permissions not universally available in OSS.

## Safe authentication

- Prefer service accounts over legacy API keys for Grafana HTTP APIs.
- Start service accounts at the `None` basic role only where the target supports granting the required granular RBAC actions, such as Enterprise or Cloud. On OSS, choose the least-privileged basic role that can perform the task and constrain folders, organizations, data sources, and backend credentials separately.
- Use separate service accounts per organization and automation owner.
- Give tokens short expirations, rotate them independently, and never place them in URLs, shell traces, examples, or evidence artifacts.
- Do not request decrypted contact-point or data-source secrets for ordinary discovery.

## Discovery output

Report version/edition, deployment owner, organization/folder or namespace, API generation selected per resource, credential type and redacted scope, pagination boundary, observed status, and unresolved ambiguity. Do not report an API as compatible until a representative authorized read succeeds against that target.

# Dashboard Engineering

Build dashboards to support a named audience and decision. Do not begin with a panel inventory.

## Define the dashboard contract

Record:

- audience and operational decision;
- service or resource scope and owner;
- method: RED, USE, Golden Signals, SLO/error budget, business process, or another declared model;
- expected time horizon, refresh need, and incident workflow;
- data sources and query languages;
- drill-down destinations and access expectations;
- authoritative owner: UI/API, file, Terraform, Git Sync, Operator, or another workflow.

Use `site-reliability-engineering` to define SLOs, page-worthiness, and reliability policy. This reference implements the resulting view in Grafana.

## Design the investigation path

Prefer an overview-to-detail flow:

1. User impact or objective status.
2. Traffic, errors, latency, and saturation appropriate to the system.
3. Scope breakdowns that distinguish widespread from localized impact.
4. Correlated infrastructure or dependency evidence.
5. Links to deeper dashboards, Explore, logs, traces, profiles, runbooks, and change records.

Avoid hard universal panel counts. Review cognitive load, screen size, query fan-out, refresh rate, and whether every panel answers a distinct question.

## Query correctness

Before styling a panel:

1. Run the query in Explore or the data source's native query surface over a representative time range.
2. Confirm metric/log/trace semantics, counter versus gauge behavior, histogram boundaries, sampling, missing data, and time zone.
3. Verify aggregation and denominator. A cumulative error count is not an error rate; averaging histogram buckets is not a latency distribution.
4. Inspect returned labels and series count. Raw paths, request IDs, user IDs, unbounded hostnames, or other high-cardinality values should not become variables, repeated panels, legends, or alert dimensions without a bound.
5. Compare query interval, minimum interval, step, resolution, and refresh rate with source resolution and retention.
6. State the limitation if real data-source access is unavailable. Do not manufacture a final query from a metric name alone.

## Variables and repetition

- Use variables to reduce duplication and preserve a stable dashboard UID.
- Give useful defaults and an explicit All behavior; avoid an unbounded All expansion.
- Test chained variables, URL encoding, multi-value queries, permissions, and empty selections.
- Repeat rows or panels only over bounded, actionable dimensions. Estimate resulting panel/query count.
- Preserve variables and time range in links when the destination understands them; avoid leaking sensitive values in URLs.

## Visualization semantics

- Choose a panel that matches the decision: time series for change, stat/gauge for a bounded current value, table for exact ranked detail, state timeline for transitions, heatmap or histogram view for distributions.
- Set explicit units, decimals, axes, legends, and null behavior. Compare like with like; normalize when capacity differs.
- Derive thresholds from an SLO, capacity limit, safety boundary, or observed baseline. Do not invent red/yellow/green cutoffs because they look plausible.
- Be cautious with stacking, dual axes, truncated axes, interpolation across gaps, transformations, and calculated fields. Each can conceal source behavior.
- Transformations run in order on prior output. Validate raw query frames and each transformation stage.

## Context and reuse

- Add panel descriptions for source, formula, units, owner, and interpretation where not obvious.
- Use annotations for deploys, incidents, configuration changes, or relevant business events.
- Use dashboard, panel, and data links for directed investigation.
- Use library panels only when shared ownership and synchronized change are desired. Review the blast radius before changing one.
- Preserve stable UIDs for durable links. Do not reuse a UID or duplicate a title in the same folder without reconciling existing resources.
- Review dashboard version history before overwrite or rollback; version history does not replace an external source of truth.

## Accessibility and readability

- Do not use color as the only carrier of status. Pair it with text, shape, thresholds, labels, or annotations.
- Use sufficient contrast, legible text, clear titles, consistent units, and non-color status labels.
- Avoid dense legends, flashing behavior, unnecessary animation, and refresh rates that prevent reading or interaction.
- Check keyboard access, focus visibility, zoom/reflow, and screen-reader output in the supported environment when accessibility is an acceptance criterion. Use `web-accessibility` for formal WCAG/assistive-technology work.
- Test a color-vision-deficiency simulation when color encodes categories or severity.

## Review and verification

Verify:

- representative normal, degraded, no-data, delayed-data, and query-error states;
- variables and links with encoded/multi-value selections;
- units, axes, thresholds, legends, and time zone;
- query count, latency, cardinality, and data-source load at expected concurrency;
- intended viewer permissions and lower-privilege denial where relevant;
- persistence through the authoritative reconciliation path;
- accessibility/readability checks required by the audience.

Call the dashboard complete only when it supports the declared decision with validated data and an explicit drill-down or recovery path.

# Provisioning and GitOps

Grafana supports multiple as-code and automation paths. They are not interchangeable. Choose one authoritative owner per resource and reconcile existing state before adopting another.

## Ownership inventory

For each UID, record:

| Field | Question |
|---|---|
| Resource | Dashboard, folder, data source, alert rule/group, receiver, policy tree, template, mute timing, RBAC object, or plugin configuration? |
| Target | Version, edition, organization, folder/namespace, environment? |
| Owner | File provider, Terraform, Git Sync, API/SDK, Operator/Crossplane, UI, or another controller? |
| Source | Repository/path/state address and revision? |
| Reconcile | Startup, poll/watch, webhook, controller loop, plan/apply, or manual request? |
| Delete behavior | `prune`, delete list, source removal, provider deletion, Terraform destroy, or policy reset? |
| Edit behavior | Is UI editing blocked, allowed but overwritten, or authoritative? |
| Rollback | Revert, prior state/config, version history, export, backup, or provider rollback? |

Inventory every potential writer. Duplicate UIDs, overlapping provider paths, copied dashboards, and multiple controllers can create conflict even when each configuration is individually valid.

## File provisioning

Self-hosted Grafana reads provisioning files for data sources, dashboards, plugins configuration, alerting, and some Enterprise RBAC behavior.

- Dashboard provisioning needs a provider YAML and a path containing dashboard definitions. Merely placing JSON under a conventional directory is not sufficient.
- Use stable UIDs. Avoid duplicate UIDs and duplicate titles in a folder.
- `allowUiUpdates: true` permits database saves but does not write changes back to the file. A later file update overwrites the database copy regardless of the JSON version field.
- Removing a provisioned dashboard source can delete the database dashboard unless `disableDeletion: true`.
- Multiple providers must not scan the same files. Grafana can reject database writes when duplicate UIDs/titles are claimed by overlapping providers.
- Polling and filesystem watch behavior depends on `updateIntervalSeconds`; mounted/network filesystems may not deliver watch events.
- Data-source `deleteDatasources` runs before add/update. `prune: true` removes resources absent from the provisioning file and can act when the file itself disappears.
- In multi-instance deployments, data-source version fields prevent older configurations from overwriting newer ones.
- File-provisioned alerting is self-hosted only and can be reloaded through an administrative operation. Reload/restart is a mutation requiring scope and rollback.

## Terraform and provider workflows

Use Terraform when the organization already operates Terraform and the provider covers the required resources.

1. Pin provider versions and inspect target Grafana compatibility.
2. Import existing resources before declaring them, preserving UIDs and folder context.
3. Review `plan` for replacement, deletion, policy-tree changes, secret handling, and provider drift.
4. Protect state as sensitive operational data; it can contain resource details and secrets.
5. Apply to a non-production or canary target when practical.
6. Verify in Grafana and on the next plan. A zero-change plan is useful drift evidence, not runtime proof.

Do not let Terraform and file/Git/UI ownership overlap for the same UID.

## Git Sync and observability as code

Grafana 12 introduced new APIs and official tooling including Git Sync, `gcx`, and Foundation SDKs. Availability and maturity depend on target version and edition.

- Confirm Git Sync support and repository permissions on the target before designing around it.
- Define branch, folder mapping, review, merge, reconciliation, conflict, and rollback behavior.
- Preserve stable UIDs and choose classic versus newer dashboard resource schemas deliberately.
- The newer dynamic/dashboard-v2 model requires the Kubernetes resource format where supported.
- Prefer the Foundation SDK over unsupported Grafonnet for new programmatic dashboard generation when the supported languages and target capabilities fit.
- Do not migrate solely because a newer workflow exists. Migrate when it creates one clear owner and a tested rollback.

## Operator and Kubernetes-native ownership

The Grafana Operator and Crossplane introduce controller reconciliation and custom resources. Use `kubernetes` for cluster mechanics and controller health. Here, verify resource scope, instance selectors, UID preservation, secret references, supported Grafana resources, controller ownership, and what happens to direct UI edits.

## Migration sequence

1. Freeze concurrent writers or establish a controlled change window.
2. Inventory live resources and all owners by UID.
3. Export or back up non-secret definitions and record version history.
4. Choose the destination owner and prove schema/version support.
5. Import/adopt without creating duplicate ownership.
6. Preview deletion, pruning, replacement, and policy-tree effects.
7. Reconcile in a test target or bounded subset.
8. Remove the old owner only after the new owner is verified.
9. Verify resource content, links, queries, permissions, alert routes, and persistence across another reconciliation cycle.
10. Confirm the old owner no longer proposes changes.

## Secrets

- Put data-source passwords, TLS private keys, custom authorization headers, and receiver credentials in `secureJsonData`, secure settings, Compose/Kubernetes secrets, or an external secret manager as supported.
- Environment interpolation is not a secret manager. Protect the source and runtime environment.
- Grafana performs two `$` substitution passes in provisioning. Use the documented escaping rules for literal dollars, including alert templates that contain `$labels` or similar expressions.
- Do not commit resolved provisioning output or exported decrypted receiver settings.

## Rollback and verification

Rollback through the authoritative owner: revert Git, restore the prior Terraform configuration/state relationship, restore provider files, or issue a version-aware API update. Do not roll back by editing Grafana's database.

After reconciliation, verify one owner per UID/path, no duplicate/drift warnings across multiple cycles, expected editability, stable URLs, successful representative queries, correct alert routing, and no unintended deletions.

# Security and Change Control

Grafana brokers access to data sources, dashboards, alerts, receivers, plugins, and administration. A dashboard permission is not a complete data-access boundary.

## Assets and trust boundaries

Protect:

- service-account and legacy API tokens;
- data-source credentials, TLS keys, custom headers, and `secureJsonData`;
- notification webhooks, integration keys, SMTP credentials, and templates;
- OAuth/OIDC/SAML/LDAP/auth-proxy secrets and identity headers;
- dashboard queries, annotations, snapshots, reports, and rendered images;
- Terraform state, provisioning repositories, backups, and Grafana database encryption keys;
- organization, folder, data-source, alerting, and receiver permissions.

Map browser/client, reverse proxy, Grafana server, database, plugins, data sources, notification receivers, identity provider, and automation as separate trust boundaries.

## Authentication and service accounts

- Use an identity provider for people and service accounts for automation.
- Avoid shared administrator credentials and legacy API keys for new automation.
- Scope service accounts to one organization and the minimum actions/resources. Use separate tokens for separate clients to support audit and rotation.
- Set short token expiration where possible. Rotate without exposing the old or new value.
- Service accounts cannot perform instance-wide user/organization administration; do not grant a human session to automation as a workaround.
- Protect auth-proxy identity headers so only the trusted proxy can set them.

## Authorization realities

- Server administrator, organization role, folder/dashboard permission, Enterprise RBAC, and data-source permission are distinct layers.
- In standard organization roles, Viewers can issue arbitrary queries to data sources they can access, not only queries embedded in allowed dashboards.
- Folder permissions are a primary dashboard boundary, but they do not constrain the backend data source by themselves.
- Restrict backend credentials and schemas, use separate organizations/data sources when needed, and use Enterprise/Cloud data-source permissions where available.
- Test both an intended role and a lower-privilege role. UI visibility is not authorization proof; test the API/query boundary.

## Data-source and outbound request safety

- Restrict allowed data-source hosts/IPs and outbound network paths where supported.
- Treat data-source URLs, plugin resources, webhooks, image/rendering URLs, and callback destinations as server-side request boundaries.
- Verify TLS certificates and server names. Do not normalize `tlsSkipVerify` into an acceptable production default.
- Use least-privilege backend credentials and read-only accounts where the workload permits.
- Never expose secure fields in diagnostics. Redacted/"configured" state is enough for ordinary inspection.

## Sharing and anonymous access

Anonymous access can allow anyone to view Viewer-accessible dashboards, list folders, dashboards, and data sources through read APIs, and issue arbitrary queries against data sources available to the anonymous organization role. Before enabling it, review every current and future dashboard, folder permission, data source, queryable data class, and API exposure.

Treat public/shared dashboards, snapshots, reports, embeds, playlists, and rendered images as separate disclosure paths. Check whether data is live or copied, whether URLs are revocable, and whether variables or annotations disclose sensitive context.

## Plugins

- Record plugin source, signature status, version, compatibility, permissions, network/data access, and rollback.
- Installation/removal is an explicit approval boundary and may require restart or migration.
- Provisioning plugin configuration does not install the plugin itself.
- Route plugin development to Grafana's plugin-development documentation; this skill covers operation and risk.

## Change classes

| Class | Examples | Gate |
|---|---|---|
| Read-only | version, health, metadata, redacted config, logs, query inspection | May proceed within authorized scope |
| Reversible configuration | dashboard update through owner, rule threshold, provider mapping | Confirm target, scope, rollback, verification |
| External effect | test alert, report/email, webhook, public sharing | Explicit receiver/audience approval |
| Access/security | password reset, user/team/service account, RBAC, auth, tokens, anonymous access | Explicit approval and lower-privilege verification |
| Destructive | delete/prune/reset policy tree, remove data source/folder/dashboard/rule/plugin, direct DB recovery | Explicit directive, backup/recovery evidence, narrow target |
| Production interruption | reload, restart, upgrade, database/plugin migration | Change window, expected interruption, rollback, external-boundary check |

Before any mutation, capture target/UID, authoritative owner, exact diff, affected users/automation, expected interruption, secret handling, rollback artifact/command, stop condition, and verification owner.

## Backup and rollback

- Back up the authoritative source and metadata needed to preserve UIDs, folders, permissions, and policy relationships.
- For self-hosted recovery, protect both the Grafana database and configuration/secret-encryption material. A database copy without required keys/configuration may not restore secure settings usefully.
- Test restore on a separate target when recovery is part of the claim.
- Do not treat dashboard version history as full platform backup.
- Do not edit the database directly except under an explicitly authorized, version-matched recovery procedure with backup and post-recovery verification.

## Security verification

Verify authentication, intended and denied authorization, secret redaction, outbound destination restrictions, audit/log evidence where available, public/anonymous exposure, plugin trust, and rollback. Use `secure-software-engineering` for a full preventive threat model and `security-audit-methodology` for an authorized assessment.

# Source Index

Research checked **2026-07-26**. Current upstream release observed through the GitHub releases API: Grafana **13.1.1**, published 2026-07-21. Operational guidance must still be refreshed against the target because supported deployments can run older major versions and Grafana's API migration is in progress.

## Canonical source and schemas

- Grafana source and releases: https://github.com/grafana/grafana
- New App Platform OpenAPI definitions: https://github.com/grafana/grafana/tree/main/packages/grafana-openapi/src/apis
- Grafana Terraform provider: https://github.com/grafana/terraform-provider-grafana
- Grafana Operator: https://github.com/grafana/grafana-operator
- Alert provisioning examples: https://github.com/grafana/provisioning-alerting-examples

Use release-pinned source or the target's Swagger for exact schemas. `main`, `latest`, and generated Swagger are live sources, not stable historical evidence.

## Live technical verification

Read-only checks on host `saru` on 2026-07-26 observed:

- Grafana `11.6.14+security-04`, commit `d88d482f3740c49ede664014fda4827a5fc2e9db`, in Docker Compose with Prometheus, Loki, and Promtail.
- `/api/health` returned `database: ok`; the container was running with zero restarts and no OOM kill, but had no Docker healthcheck.
- Grafana configuration, data, and logs were stored in named volumes. Dashboard JSON/provider files and a Loki data-source file existed under `/etc/grafana/provisioning`.
- Two dashboard providers, `magnus919` and `Traefik`, both polled `/etc/grafana/provisioning/dashboards` every 30 seconds with `disableDeletion: false`.
- Bounded logs repeatedly reported duplicate dashboard UIDs/titles and stated that both providers had no database write permissions because of duplicates.
- Protected legacy and new-style paths returned `401` without credentials. This proves the authentication boundary, not route compatibility or resource existence.

No files, services, tokens, Grafana resources, or external receivers were changed. No authenticated API inventory, data-source query, alert evaluation, notification delivery, or resolved notification was performed.

## Source evaluation

The retained product claims use Tier 1 official documentation, canonical source/schema repositories, release metadata, and direct read-only runtime evidence. Grafana Labs documentation is authoritative for supported behavior but is a vendor source and sometimes points to newer Swagger versions than its prose examples. The live target provides strong evidence for one Grafana 11 failure pattern, not a universal behavior claim.

Community posts, generic dashboard lists, and unsourced tutorials were excluded because primary documentation and runtime evidence covered the required scope. Existing repository PromQL examples were not reused because several require independent semantic validation.

## Refresh rules

Recheck sources and the target when any of these change:

- Grafana major/minor version, edition/license, Cloud stack generation, or deployment owner;
- `/api` or `/apis` route, API group/version, namespace, schema, pagination, provenance, or permission;
- dashboard classic/v2 schema, dynamic dashboards, Git Sync, `gcx`, Foundation SDK, or Operator support;
- alert-rule, recording-rule, receiver, policy, template, silence, or time-interval API/provisioning behavior;
- provisioning watch/poll, edit, delete, prune, version, interpolation, or hot-reload behavior;
- service-account, RBAC, data-source permission, anonymous/public sharing, plugin signature, or request-security behavior.

Always refresh destructive, access-control, secret, and production-routing instructions immediately before use.

# Troubleshooting Grafana

Separate evidence from inference. Diagnose in layers and change configuration only after identifying the failing plane.

## Baseline evidence

Collect a bounded record:

- exact version/edition/commit and deployment owner;
- target URL, organization/folder, auth method, and permission scope;
- process/container state, restart/OOM state, listener, and `/api/health`;
- effective non-secret configuration paths and provisioning ownership;
- bounded server logs covering the failure window;
- browser/network response or API status with secrets removed;
- data-source query evidence and timestamps;
- resource UID/provenance and last known change.

Do not dump complete environment variables, configuration, logs, dashboard JSON, Terraform state, or API responses into evidence.

## Blank or misleading panel

1. Confirm dashboard UID/version, panel, time range, time zone, refresh, and variables.
2. Inspect query response and error in Query Inspector or Explore.
3. Run the smallest equivalent query against the same data source.
4. Check data-source UID, permission, authentication, TLS, proxy/network reachability, and source retention.
5. Inspect labels, aggregation, interval/step, transformations in order, field overrides, null handling, and hidden series.
6. Compare with a known time containing data and test no-data behavior.

Do not "fix" a blank panel by widening time range, replacing nulls, or changing transformations until source absence and query semantics are distinguished.

## Data-source authentication or query failure

1. Identify data-source type/plugin version, access mode, URL class, and credential owner without revealing secure fields.
2. Use the Grafana data-source health check, then a representative bounded query.
3. Compare Grafana-to-source network/DNS/TLS behavior with the source's own health and auth logs.
4. Check least-privilege grants, token expiry, certificate chain/server name, proxy whitelist/request security, and time skew.
5. Separate Grafana permission to query from backend permission to read the requested data.

Route backend repair to the relevant data-source skill.

## Provisioning failure or drift

1. Enumerate providers/controllers, paths, UIDs, folders, scan intervals, edit/delete flags, Terraform state addresses, and Git/Operator owners.
2. Search bounded logs for provisioning errors, duplicate UIDs/titles, parse failures, permissions, and reconciliation outcomes.
3. Compare source hashes/revisions with the running object and database/API metadata.
4. Detect overlapping provider paths and multiple writers before editing any dashboard.
5. Review source removal, `prune`, delete lists, and policy-tree replacement risk.

### Known live failure pattern

On a Grafana 11.6.14 Compose target observed on 2026-07-26, `/api/health` reported `database: ok` while two dashboard providers scanned the same directory. Every observed poll in the bounded log window produced duplicate UID/title warnings, and Grafana reported that both providers lacked database write permission because of the duplicates. The safe diagnosis is overlapping ownership, not a failed database. Remediation must make provider scopes non-overlapping or select one owner, preserve files/UIDs, and verify warning cessation across more than one poll. This observation is a failure pattern, not a universal version-specific bug.

## Alert rule not evaluating

1. Confirm rule type/provenance, enabled/paused state, group interval, scheduler state, and organization/folder.
2. Run query/expression components over the rule's relative time range.
3. Check data-source auth and support for server-side alert queries.
4. Inspect no-data/error state and evaluation logs.
5. Check rule-instance cardinality and label conflicts.

## Firing alert does not notify

1. Capture actual firing labels and state transition time.
2. Trace the complete policy path, inherited receiver/timing, continue behavior, grouping, silences, and mute timings.
3. Check contact-point configuration with secrets redacted.
4. Account for group wait/interval and repeat timing before calling delivery late.
5. Use a controlled test receiver if authorized; inspect Grafana and receiver-side evidence.
6. Verify resolved delivery separately.

## Reverse proxy, subpath, or authentication failure

1. Test Grafana directly on its internal listener and through the proxy boundary.
2. Compare scheme, host, domain, `root_url`, subpath settings, forwarded headers, cookies, WebSocket routes, and identity headers.
3. Check redirect chains, callback URLs, SameSite/Secure cookie behavior, proxy timeouts, and body/header limits.
4. Verify the proxy does not expose administrative or internal data-source endpoints unintentionally.
5. Route TLS, middleware, and proxy configuration changes to the proxy skill.

## Plugin and migration failures

- Record Grafana and plugin versions, signature status, architecture, installation owner, and startup logs.
- Disable or remove a plugin only with explicit approval and a dashboard/data-source impact review.
- Before upgrades, verify database backup/restore, plugin compatibility, schema migration logs, storage headroom, and rollback support.
- Do not downgrade across database migrations or edit migration tables without a documented, explicitly authorized recovery path.

## Stop conditions

Stop before mutation when the target, owner, credential scope, production impact, or rollback is unknown. After two materially different diagnostic paths fail, report the evidence and access needed instead of trying unbounded configuration changes.

Report diagnosis as: observed evidence, supported inference, competing explanations, safe next test, mutation/approval boundary, and unverified delivery boundary.
