Grafana Agent Setup for Lab Nodes Monitoring Overview The grafana_agent Ansible role deploys Grafana Agent (static mode) on Lab Nodes to collect system metrics and forward them to a central Mimir instance. This setup replaces or coexists with the previous Prometheus + node_exporter approach, providing a lightweight agent that pushes metrics into Mimir for long-term storage and Grafana dashboards.

Testnode Access Summary We have about 250 baremetal testnodes that get automatically reserved (locked) and unlocked by teuthology “workers.” Workers are daemons on the teuthology.front.sepia.ceph.com VM that are fed jobs via a beanstalk queue. This page will cover setting up your workstation to lock and unlock testnodes as well as schedule teuthology suites.
