The TiKV monitoring framework adopts two open-source projects: Prometheus and Grafana. TiKV uses Prometheus to store the monitoring and performance metrics, and uses Grafana to visualize these metrics.

About Prometheus in TiKV

As a time series database, Prometheus has a multi-dimensional data model and flexible query language. Prometheus consists of multiple components. Currently, TiKV uses the following components:

• Prometheus Server: to scrape and store time series data
• Client libraries: to customize necessary metrics in the application
• Pushgateway: to receive the data from Client Push for the Prometheus main server
• AlertManager: for the alerting mechanism
