Docker image: Promtail

Promtail is an agent which ships the contents of local logs to a private Grafana Loki instance or Grafana Cloud. It is usually deployed to every machine that has applications needed to be monitored.

It primarily:

  • Discovers targets
  • Attaches labels to log streams
  • Pushes them to the Loki instance.

Usage​

Set promtail_enabled: true in your inventories/<your_inventory>/group_vars/nas.yml file.
