Prometheus Architecture

Basic Architecture

• Prometheus server: Prometheus server: the server which scrapes and stores the metrics data
• Instrumented Application or Exporter: instrumented application that exposes its metrics, or an exporter that exposes metrics of another application.
• Alert Manager: to raise alerts based on preset rules.

Prometheus Components

• The main Prometheus server which scrapes and stores time series data
• client libraries for instrumenting application code
• a push gateway for supporting short-lived jobs
• special-purpose exporters for services like HAProxy, StatsD, Graphite, etc.
• an alertmanager to handle alerts
• various support tools

Note: Grafana or other API consumers can be used to visualize the collected data.
