Ansible Collection - fahcsim.grafana_stack

Version 1.1.0

This should be enough to set up centralized logging and monitoring fairly easily. Prometheus will be configured to monitor every host in the inventory (see roles/prometheus/templates/prometheus.yml.j2). Loki agents will point to the loki server(configured as loki_server variable). All of these services are installed as binaries with systemd.

This collection has a role for each of the following:

Prometheus
Loki
Prometheus Node Exporter
Promtail

Requirements

For the prometheus config to work correctly, the ansible inventory hostname of each server must be a DNS name that your prometheus server can resolve. Current supported distributions are Debian 10/11 and Ubuntu 20/22. It may work on other distros, but it has not been tested.

Example Playbook

- name: bootstrap monitoring server
  hosts: monitoring
  become: True
  vars:
    loki_server: loki_server.local
  roles:
    - fahcsim.grafana_stack.prometheus
    - fahcsim.grafana_stack.loki
    - fahcsim.grafana_stack.prometheus_node_exporter
    - fahcsim.grafana_stack.promtail
    - fahcsim.grafana_stack.grafana

Updating

Each service can be updated by changing the <service>_version variable, as long as a corresponding version exists in the project's github repo.

Current Defaults

Prometheus

prometheus_version: 2.37.0
