  Query Grafana dashboards and Prometheus metrics for service health, LLM latency, and infrastructure monitoring.
  Use this skill when the user asks about service health, monitoring, alerts, or performance metrics.

# Grafana Integration

## Connection

- **Base URL**: `$GRAFANA_URL` (e.g. `https://your-org.grafana.net`)
- **Auth**: `Authorization: Bearer $GRAFANA_API_TOKEN` (service account token)
- **Credentials**: `GRAFANA_URL`, `GRAFANA_API_TOKEN` from Settings → Data sources
- **Caching**: 10-minute cache for metadata; query results are NOT cached (time-sensitive)
- **Key datasource**: Prometheus UID `grafanacloud-prom`

## Server Lib & API Routes

- **File**: `server/lib/grafana.ts`

### Exported Functions

| Function                                      | Description                             |
| --------------------------------------------- | --------------------------------------- |
| `listDashboards(query?)`                      | Search dashboards by query              |
| `getDashboard(uid)`                           | Full dashboard JSON with panels         |
| `getDatasources()`                            | List all datasources                    |
| `getAlertRules()`                             | All alert rules (flattened from groups) |
| `getAlertInstances()`                         | Currently firing alert instances        |
| `queryDatasource(uid, queries[], from?, to?)` | Proxy to Grafana's `/api/ds/query`      |

### API Routes

| Route                                | Description                               |
| ------------------------------------ | ----------------------------------------- |
| `GET /api/grafana/dashboards`        | Search dashboards                         |
| `GET /api/grafana/dashboard?uid=...` | Full dashboard JSON                       |
| `GET /api/grafana/datasources`       | List datasources                          |
| `GET /api/grafana/alerts`            | Alert rules and firing instances          |
| `POST /api/grafana/query`            | Query datasource (Prometheus, Loki, etc.) |

### Agent Action

Use `grafana` for agent-facing Grafana work. Do not call `/api/grafana/*`
directly from the agent.

| Mode          | Args                                     | Description                      |
| ------------- | ---------------------------------------- | -------------------------------- |
| `dashboards`  | `search`                                 | Search dashboards                |
| `dashboard`   | `uid`                                    | Full dashboard JSON              |
| `datasources` |                                          | List datasources                 |
| `alerts`      |                                          | Alert rules and firing instances |
| `query`       | `datasourceUid`, `queries`, `from`, `to` | Query a datasource               |

### Dashboard

- `/adhoc/engineering` — Engineering dashboard (mirrors a Grafana dashboard by UID)

## Grafana Response Frame Format

```
{ results: { [refId]: { frames: [{ schema: { fields }, data: { values } }] } } }
```

- `values[0]` = timestamps (epoch ms), `values[1+]` = metric values
- Series labels from `schema.fields[i].labels` (e.g. `{ model: "claude-3.5" }`)
- Transform to Recharts: `{ time: number, [seriesName]: number }[]`

## Template Variables

- `$CodegenMode` → default `quality-v4`
- `$AIModel` → regex pattern, default `.*` (all)
- `$environment` → `cloud` or `cloud-v2`, default `cloud`
- Variables interpolated via string replace before querying

## Key Prometheus Metrics

- **Codegen**: `vcpcodegen_completion_total`, `vcpcodegen_completion_latency_bucket`, `vcpcodegen_feedback_total`, `vcpcodegen_error_total`
- **LLM**: `llm_completion_cost_total`, `llm_input_tokens_total`, `llm_output_tokens_total`, `llm_latency_bucket`, `llm_failures_total`, `llm_completions_total`
- **Projects**: `projects_proposed_config_total`, `projects_status_total`, `projects_remote_machine_*`, `projects_start_duration_bucket`
- **API/Runtime**: `api_request_total`, `with_span_duration_bucket`, `memory_heap_usage_percent_bucket`
- **Fly.io**: `fly_endpoint_total`, `fly_machine_*`
- **GitHub**: `builderbot_pr_created_total`, `builderbot_pr_closed_total`

## Key Patterns & Gotchas

- `queryDatasource` constructs body with datasource UID in each query target; timestamps as string ms
- `getAlertRules` flattens nested rule groups from unified alerting API
- `getAlertInstances` handles both array and wrapped object response shapes
- POST helper caches by default (fine for idempotent endpoints) but `queryDatasource` skips cache
- Heatmap panels render as multi-series line/area (Recharts has no native heatmap; PromQL `histogram_quantile()` computes quantiles)

## Incident Investigation Pattern

For production issues, query Grafana/Prometheus FIRST:

1. LLM latency by model (`llm_latency_bucket`)
2. Request rates (`api_request_total`)
3. Error rates (`llm_failures_total`)
4. Instance counts (via Cloud Monitoring)

Then check Agent-Native Analytics Monitoring -> Errors for captured application
issues, external Sentry when connected, and Cloud Logging for raw logs.
