# grafana

A rule that sets one style for Grafana dashboards, alerts and data sources as code: structure, visual standards, query performance.

## What it does

The rule treats Grafana dashboards, alerts and data sources as code artifacts. Everything lives in JSON or YAML, sits in Git and gets provisioned through the Grafana API. Manual UI edits are fine only for early prototyping, because you lose version history and review.

For complex or generated dashboards the rule prefers the Foundation SDKs for Go, Python and TypeScript over hand-written JSON. Templated variables are mandatory — without them you end up with duplicate prod and dev dashboards and hardcoded instance names. Prometheus counters go through `rate()` or `irate()`, never `sum()`, otherwise the panel shows a cumulative total instead of a rate.

The visual rules are strict: Y-axis always zero-based, thin lines, at most 4 metrics per panel. Auto-refresh should sit at 5 or 15 minutes; anything under a minute belongs on alerting dashboards. Timing metrics need care too — `mean` and `median` hide outliers, so the rule pushes `max`, `p99` and `p75` instead.

## Requirements
- Works with: Grafana

## Install

### Cursor (native platform)

**Manually: put the files in place**
- File: `.cursor/rules/grafana.mdc` — Frontmatter: description, globs, alwaysApply

### Claude Code

**Manually: put the files in place**
- File: `.claude/rules/grafana.md` — The paths frontmatter field limits the files: move globs from the source into paths

### Codex

**AGENTS.md**
- Codex reads AGENTS.md: paste the rule text there

### GitHub Copilot

**Manually: put the files in place**
- File: `.github/instructions/grafana.instructions.md` — The applyTo field sets which files it applies to: move globs from the source into applyTo

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/rules/grafana.md`

### Cline

**Manually: put the files in place**
- File: `.clinerules/grafana.md`

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/sanjeed5/awesome-cursor-rules-mdc/tree/HEAD/rules-mdc/grafana.mdc

## When to use it
- move Grafana dashboards into Git files instead of manual UI edits
- kill duplicate prod and dev dashboards with templated variables
- fix panels where a counter uses `sum()` and climbs forever
- make panels consistent: zero-based Y-axis, no more than 4 lines
- cut load on the metric database with a sane auto-refresh interval

## Example prompts
- Build a service dashboard following the grafana rule: instance and environment variables, zero-based Y-axis
- Review my Prometheus queries — counters should use rate(), not sum()
- Write the alerts and data sources as YAML so I can provision them through the Grafana API

# Grafana Best Practices

Our team treats Grafana dashboards, alerts, and data sources as first-class code artifacts. This means applying software engineering principles: version control, peer review, automated testing, and CI/CD. Adhere strictly to these guidelines to ensure our observability platform remains robust, maintainable, and actionable.

## 1. Code Organization and Structure

Define all Grafana resources declaratively using Observability as Code (OaC). This enables Git-based workflows, automated provisioning, and consistent deployments.

### 1.1. Declarative Configuration (OaC)

**Always** define dashboards, alerts, and data sources in JSON/YAML files. Store these in Git and provision them via Grafana's API. Avoid manual UI configuration for anything beyond initial prototyping.

❌ **BAD**: Manual UI changes, no version history.
✅ **GOOD**: Git-versioned JSON/YAML files, automated provisioning.

```json
// my-service-dashboard.json
{
  "apiVersion": 1,
  "title": "My Service Overview",
  "uid": "my-service-overview",
  "panels": [
    // ... panel definitions ...
  ],
  "templating": {
    "list": [
      // ... variables ...
    ]
  }
}
```

### 1.2. Utilize Foundation SDKs

For complex or dynamically generated dashboards, **prefer** using Grafana Foundation SDKs (Go, Python, TypeScript) to programmatically define resources. This provides strong typing, validation, and better code reusability than raw JSON manipulation.

```typescript
// dashboard.ts (using TypeScript SDK)
import { Dashboard, Row, Panel, GraphPanel } from '@grafana/sdk';

const dashboard = new Dashboard({
  title: 'Service Health',
  uid: 'service-health',
  panels: [
    new Row({
      panels: [
        new GraphPanel({
          title: 'CPU Utilization',
          targets: [{ expr: 'sum(rate(node_cpu_seconds_total{mode="idle"}[5m])) by (instance)' }],
          yAxis: { min: 0 }
        })
      ]
    })
  ]
});

console.log(JSON.stringify(dashboard.toGrafanaJson(), null, 2));
```

### 1.3. Templated Variables

**Mandate** the use of templated variables for dynamic filtering and reusability across environments or instances. This prevents dashboard duplication.

❌ **BAD**: Hardcoded instance names or environment-specific queries.
```json
// Duplicated dashboard for 'prod' and 'dev'
{ "title": "Prod CPU Usage", "targets": [{ "expr": "node_cpu_seconds_total{instance='prod-app-01'}" }] }
{ "title": "Dev CPU Usage", "targets": [{ "expr": "node_cpu_seconds_total{instance='dev-app-01'}" }] }
```
✅ **GOOD**: Single dashboard with variables.
```json
{
  "title": "Service CPU Usage",
  "templating": {
    "list": [
      { "name": "instance", "type": "query", "query": "label_values(node_cpu_seconds_total, instance)" },
      { "name": "environment", "type": "custom", "options": ["prod", "dev"], "current": { "value": "prod" } }
    ]
  },
  "panels": [
    {
      "title": "CPU Utilization on $instance ($environment)",
      "targets": [{ "expr": "node_cpu_seconds_total{instance=\"$instance\", env=\"$environment\"}" }]
    }
  ]
}
```

## 2. Common Patterns and Anti-patterns

Design dashboards for immediate diagnostic value and clarity.
