Summary

  • Add node_exporter ansible role to enable textfile collector at /opt/homebrew/var/node_exporter/textfile
  • Add transmission_metrics ansible role with bash script + LaunchAgent that collects metrics every 60s
  • Update grafana role to provision dashboards from JSON files
  • Add transmission dashboard with status, torrent counts, transfer speeds, and time series graphs

Test plan

  • ansible-playbook --check --diff passes
  • Dependency meta ensures node_exporter and transmission run before transmission_metrics
  • Apply playbook and verify metrics appear in prometheus
  • Verify dashboard loads in grafana at https://grafana.tail8d86e.ts.net

Transmission doesn't support HEAD requests, so use -i flag with sed to
parse only the HTTP headers (stopping at the blank line before body).
Also anchor grep pattern to line start to avoid matching HTML content.
