Khám phá

Grafana is the leading open-source platform for monitoring and observability, turning your time-series data into beautiful, interactive dashboards and visualizations. Grafana connects to dozens of data sources including Prometheus, InfluxDB, Elasticsearch, PostgreSQL, MySQL, CloudWatch, and many more, allowing you to query, visualize, alert, and explore your metrics, logs, and traces from a single interface. Whether you're monitoring infrastructure, applications, IoT devices, or business metrics, Grafana provides the tools to create stunning dashboards that help you understand your data at a glance.

Chỉ dẫn cài đặt

Ubuntu Installation:
# Add APT repository
sudo apt-get install -y apt-transport-https software-properties-common
sudo wget -q -O /usr/share/keyrings/grafana.key https://apt.grafana.com/gpg.key
echo "deb [signed-by=/usr/share/keyrings/grafana.key] https://apt.grafana.com stable main" | sudo tee -a /etc/apt/sources.list.d/grafana.list

# Install
sudo apt-get update
sudo apt-get install grafana

# Start service
sudo systemctl start grafana-server
sudo systemctl enable grafana-server

# Access at http://localhost:3000
# Default login: admin/admin
Docker Installation:
docker run -d --name=grafana -p 3000:3000 \
  -v grafana-storage:/var/lib/grafana \
  grafana/grafana-oss:latest
Docker Compose (with Prometheus):
version: '3'
services:
  grafana:
    image: grafana/grafana-oss:latest
    ports:
      - "3000:3000"
    environment:
      - GF_SECURITY_ADMIN_PASSWORD=admin
      - GF_INSTALL_PLUGINS=grafana-clock-panel
    volumes:
      - grafana-data:/var/lib/grafana
  
  prometheus:
    image: prom/prometheus:latest
    ports:
      - "9090:9090"
    volumes:
      - ./prometheus.yml:/etc/prometheus/prometheus.yml
      - prometheus-data:/prometheus

volumes:
  grafana-data:
  prometheus-data:

Gợi ý cấu hình

grafana.ini Configuration:
[server]
http_port = 3000
domain = grafana.yourdomain.com
root_url = https://grafana.yourdomain.com

[database]
type = postgres
host = localhost:5432
name = grafana
user = grafana
password = password

[security]
admin_user = admin
admin_password = secure_password

[smtp]
enabled = true
host = smtp.gmail.com:587
user = your-email@gmail.com
password = your-app-password
from_address = grafana@yourdomain.com
Add Prometheus Data Source (API):
curl -X POST http://admin:password@localhost:3000/api/datasources \
  -H "Content-Type: application/json" \
  -d '{
    "name": "Prometheus",
    "type": "prometheus",
    "url": "http://localhost:9090",
    "access": "proxy",
    "isDefault": true
  }'
Dashboard JSON (Simple CPU Dashboard):
{
  "dashboard": {
    "title": "CPU Monitoring",
    "panels": [{
      "title": "CPU Usage",
      "type": "graph",
      "targets": [{
        "expr": "100 - (avg(irate(node_cpu_seconds_total{mode=\"idle\"}[5m])) * 100)"
      }]
    }]
  }
}
Best Practices:
- Use folders to organize dashboards
- Implement dashboard variables for flexibility
- Set up alerting rules with proper thresholds
- Use PostgreSQL/MySQL in production (not SQLite)
- Enable HTTPS with reverse proxy (Nginx/Caddy)
- Configure authentication (OAuth, LDAP, SAML)
- Regular backups of dashboards and config
- Monitor Grafana itself with Prometheus
