# Grafana Dashboards

Create and manage production-ready Grafana dashboards for comprehensive system observability.

## Purpose

Design effective Grafana dashboards for monitoring applications, infrastructure, and business metrics.

## When to Use

- Visualize Prometheus metrics
- Create custom dashboards
- Implement SLO dashboards
- Monitor infrastructure
- Track business KPIs

## Dashboard Design Principles

### 1. Hierarchy of Information

```text
┌─────────────────────────────────────┐
│  Critical Metrics (Big Numbers)     │
├─────────────────────────────────────┤
│  Key Trends (Time Series)           │
├─────────────────────────────────────┤
│  Detailed Metrics (Tables/Heatmaps) │
└─────────────────────────────────────┘
```

### 2. RED Method (Services)

- **Rate** - Requests per second
- **Errors** - Error rate
- **Duration** - Latency/response time

### 3. USE Method (Resources)

- **Utilization** - % time resource is busy
- **Saturation** - Queue length/wait time
- **Errors** - Error count

## Dashboard Structure

### API Monitoring Dashboard

```json
{
  "dashboard": {
    "title": "API Monitoring",
    "tags": ["api", "production"],
    "timezone": "browser",
    "refresh": "30s",
    "panels": [
      {
        "title": "Request Rate",
        "type": "graph",
        "targets": [
          {
            "expr": "sum(rate(http_requests_total[5m])) by (service)",
            "legendFormat": "{{service}}"
          }
        ],
        "gridPos": { "x": 0, "y": 0, "w": 12, "h": 8 }
      },
      {
        "title": "Error Rate %",
        "type": "graph",
        "targets": [
          {
            "expr": "(sum(rate(http_requests_total{status=~\"5..\"}[5m])) / sum(rate(http_requests_total[5m]))) * 100",
            "legendFormat": "Error Rate"
          }
        ],
        "alert": {
          "conditions": [
            {
              "evaluator": { "params": [5], "type": "gt" },
              "operator": { "type": "and" },
              "query": { "params": ["A", "5m", "now"] },
              "type": "query"
            }
          ]
        },
        "gridPos": { "x": 12, "y": 0, "w": 12, "h": 8 }
      },
      {
        "title": "P95 Latency",
        "type": "graph",
        "targets": [
          {
            "expr": "histogram_quantile(0.95, sum(rate(http_request_duration_seconds_bucket[5m])) by (le, service))",
            "legendFormat": "{{service}}"
          }
        ],
        "gridPos": { "x": 0, "y": 8, "w": 24, "h": 8 }
      }
    ]
  }
}
```

## Panel Types

### 1. Stat Panel (Single Value)

```json
{
  "type": "stat",
  "title": "Total Requests",
  "targets": [
    {
      "expr": "sum(http_requests_total)"
    }
  ],
  "options": {
    "reduceOptions": {
