Quickstart
- prometheus polls HTTP endpoints for collected metrics
- these endpoints are called exporters, and they are generated/exposed using clients
- you can configure rules to persist data, or emit alerts when a metric fails
xdg-open localhost:9090 # prometheus-ui promtool check rules /path/to/example.rules.yml # validate rule amtool check-config alertmanager.yml # validate alertmanager config
Notes
Setup
