Grafana-优化

配置缓存

rpm 安装的路径在/var/lib/grafana

# grafana.ini
[metrics]
# Enable caching of metric results
enable_metrics_source_cache = true

# Cache results for this many seconds
metrics_source_cache_ttl_seconds = 60

数据源缓存

某些数据源插件支持自己的缓存机制，例如 Prometheus 插件。

# grafana.ini
[datasources]
# Prometheus data source cache settings
prometheus:
  # Enable caching
  enable_metrics_source_cache = true
  # Cache results for this many seconds
  metrics_source_cache_ttl_seconds = 60

配置 Nginx 反向代理

Nginx 可以作为 Grafana 的反向代理，提供静态缓存功能

server {
   
  listen 80;
  server_name grafana.example.com;

  location / {
   
    proxy_pass http://localhost:3000;
    proxy_set_header Host $host;
    proxy_set_header X-Real-IP $remote_addr;
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    proxy_set_header X-Forwarded-Proto $scheme;

    # Enable caching
    proxy_cache_valid 200 60m;
    proxy_cache_use_stale error timeout invalid_header http_500 http_502 http_503 http_504;
    proxy_cache_key "$scheme$request_method$host$request_uri";
  }
}
