StatsD - Graphite - Grafana

发表于

#1. StatsD - metrics data collecting

  • In your application code, use the StatsD client (e.g. Java client library) to collect and send the statistics and aggregation data to StatsD server;
  • Not need to pre-define the metrics in anywhere, just place them into your application code;
  • By default, stats data are aggregated and sent to Graphite server by every 10 seconds, so think this near-realtime;

#2. Graphite - metrics data graphing and storage

  • Store numeric time-series data: The metric data would be stored into Graphite server (include a Whisper database);
  • Render the graph for metrics data per the metrics demand;
  • The pre-built UI dashboard is not powerful shown as below, but can easily use it to view the metrics data;
  • For production environment, Graphite server should be running as cluster instead of stand-alone server;

#3. Grafana - powerful dashboard for visualizing the metrics data

  • easy to integrate with Graphite to visualize the metrics data;
  • input the Graphite HTTP URL to link to Graphite as data source;
  • powerful pre-built reporting charts and dashboard;

#4. Sample Code:

  • easy to feed the data to StatsD -> Graphite -> Grafana
