Description

It's possible to use `radosgw-admin` commands to query for a Ceph Object Storage user's quota and usage. It would be great to get this information available to Prometheus :)

e.g.

$ sudo radosgw-admin user info --uid=prometheus | jq .user_quota
{
  "enabled": true,
  "check_on_raw": false,
  "max_size": 2147483648000,
  "max_size_kb": 2097152000,
  "max_objects": -1
}

and

$ sudo radosgw-admin user stats --uid=prometheus
{
    "stats": {
        "total_entries": 36,
        "total_bytes": 455580945824,
        "total_bytes_rounded": 455581016064
    },
    "last_stats_sync": "2020-03-23 23:12:35.254193Z",
    "last_stats_update": "2020-03-23 23:12:35.241044Z" 
}

This would allow us to create alerts when a) users are nearing their quota and b) when they've reached their quota.

  • Tags set to administration, rgw, monitoring
  • Subject changed from Expose object storage users quotas and usage to mgr/prometheus: Expose object storage users quotas and usage

#2 Updated by Konstantin Shalygin about 2 months ago

Currently this implemented in this exporter.
Query per user is slow, to be implemented RGW API should have "all users stats" query. Currently is only per user possible.
