Grafana Dashboards

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

Do not use this skill when

• The task is unrelated to grafana dashboards
• You need a different domain or tool outside this scope

Instructions

• Clarify goals, constraints, and required inputs.
• Apply relevant best practices and validate outcomes.
• Provide actionable steps and verification.

Purpose

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

Use this skill when

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

Dashboard Design Principles

1. Hierarchy of Information

┌─────────────────────────────────────┐
│  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
