Architecture

Pigsty’s monitoring system is built in part entirely on open source components, with core components including

• Grafana for presenting the monitoring interface

• Prometheus for collecting and storing query time series metrics

• Node Exporter for exposing machine metrics

• Self-developed PG Exporter for exposing database and connection pools

• Consul for service discovery

Example

Taking the four-node sandbox environment that comes with Pigsty as an example, the main components involved in Pigsty are shown below.
