Description of problem

Cluster goes HEALTH_ERR after enabling telegraf plugin.

Environment

  • ceph version string: 15.2.13
  • Platform (OS/distro/release): Proxmox 6.4-8
  • Cluster details (nodes, monitors, OSDs): 5 nodes, 5mons, 20 OSD
  • Browser used (e.g.: Version 86.0.4240.198 (Official Build) (64-bit)): FF89

Run Octopus 15.2.13 (In earlier Versions an issue, too), enable telegraf plugin with:

ceph telegraf config-set address udp://:8094
ceph telegraf config-set interval 10
ceph mgr module enable telegraf
