Subject: monitoring: improve hardware Grafana dashboard panels
X-Git-Url: http://git-server-git.apps.pok.os.sepia.ceph.com/?a=commitdiff_plain;h=5dd6807e3187ba6792f69736b5e4d396832b1686;p=ceph.git

monitoring: improve hardware Grafana dashboard panels

- CPU/NVMe temp: change from stat to gauge panels with colored
  arc thresholds (green/yellow/red) and proper °C units
- Health panels: wrap queries in max() aggregation to show
  single worst-case value instead of overlapping series
- Pie charts: switch to donut style with visible legends
- Fan RPM: use locale unit for comma formatting instead of
  short which auto-scaled to "K"
- Fix temperature panels units
- Add Device List and Platform Firmware table panels

Fixes https://tracker.ceph.com/issues/77723
