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

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

        "datasource": "Prometheus",
        "query": "label_values(kube_service_info{namespace=\"$namespace\"}, service)",
        "refresh": 1,
        "multi": true
      }
    ]
  }
}

Use Variables in Queries

sum(rate(http_requests_total{namespace="$namespace", service=~"$service"}[5m]))

{
  "alert": {
    "name": "High Error Rate",
    "conditions": [
      {
        "evaluator": {
          "params": [5],
          "type": "gt"
        },
        "operator": { "type": "and" },
        "query": {
          "params": ["A", "5m", "now"]
        },
        "reducer": { "type": "avg" },
        "type": "query"
      }
    ],
    "executionErrorState": "alerting",
    "for": "5m",
    "frequency": "1m",
    "message": "Error rate is above 5%",
    "noDataState": "no_data",
    "notifications": [{ "uid": "slack-channel" }]
  }
}

Dashboard Provisioning

dashboards.yml:

apiVersion: 1

providers:
  - name: "default"
    orgId: 1
    folder: "General"
    type: file
    disableDeletion: false
    updateIntervalSeconds: 10
    allowUiUpdates: true
    options:
      path: /etc/grafana/dashboards

Common Dashboard Patterns

Infrastructure Dashboard

Key Panels:

CPU utilization per node
Memory usage per node
Disk I/O
Network traffic
Pod count by namespace
Node status

Reference: See assets/infrastructure-dashboard.json

Database Dashboard

Key Panels:

Queries per second
Connection pool usage
Query latency (P50, P95, P99)
Active connections
Database size
Replication lag
Slow queries

Reference: See assets/database-dashboard.json

Application Dashboard

Key Panels:

Request rate
Error rate
Response time (percentiles)
Active users/sessions
Cache hit rate
Queue length

Best Practices

Start with templates (Grafana community dashboards)
Use consistent naming for panels and variables
Group related metrics in rows
Set appropriate time ranges (default: Last 6 hours)
Use variables for flexibility
Add panel descriptions for context
Configure units correctly
Set meaningful thresholds for colors
Use consistent colors across dashboards

10. Test with different time ranges

Dashboard as Code

Terraform Provisioning

resource "grafana_dashboard" "api_monitoring" {
  config_json = file("${path.module}/dashboards/api-monitoring.json")
  folder      = grafana_folder.monitoring.id
}

resource "grafana_folder" "monitoring" {
  title = "Production Monitoring"
}

Ansible Provisioning

- name: Deploy Grafana dashboards
  copy:
    src: "{{ item }}"
    dest: /etc/grafana/dashboards/
  with_fileglob:
    - "dashboards/*.json"
  notify: restart grafana

Us Gov Shutdown Tracker

by fleurytian

×1

Track and analyze US government shutdown liquidity impacts by monitoring TGA (Treasury General Account), bank reserves, EFFR, and SOFR data from FRED API. Use when user wants to (1) analyze current or past government shutdown effects on financial markets, (2) track liquidity conditions during fiscal policy disruptions, (3) assess "stealth tightening" effects, (4) compare shutdown episodes across different monetary policy regimes (QE vs QT), or (5) generate liquidity stress reports with historical context. Recommended usage frequency is weekly on Wednesdays after TGA/reserve data releases.

Azure Monitor Query SDK for Python. Use for querying Log Analytics workspaces and Azure Monitor metrics.

Use this skill when you need to search Datadog logs, query metrics, tail logs in real-time, trace distributed requests, investigate errors, compare time periods, find log patterns, check service health, or export observability data.

Write comprehensive clinical reports including case reports (CARE guidelines), diagnostic reports (radiology/pathology/lab), clinical trial reports (ICH-E3, SAE, CSR), and patient documentation (SOAP, H&P, discharge summaries). Full support with templates, regulatory compliance (HIPAA, FDA, ICH-GCP), and validation tools.
