collectd doesn't push all stats

[Sean Purdy <s.purdy@xxxxxxxxxxxxxxxx>]

Hi,


The default collectd ceph plugin seems to parse the output of "ceph daemon <daemon type> perf dump" and generate graphite output.  However, I see more fields in the dump than in collectd/graphite

Specifically I see get stats for rgw (ceph_rate-Client_rgw_nodename_get) but not put stats (e.g. ceph_rate-Client_rgw_nodename_put)

e.g. (abbreviated) dump says:
{
    "client.rgw.store01": {
        "req": 164927606,
        "failed_req": 43482,
        "get": 162727054,
        "put": 917996,
    }
}
but put stats don't show up.

Anybody know how to tweak the plugin to select the stats you want to see?  e.g. monitor paxos stuff doesn't show up either.  Perhaps there's a deliberate limitation somewhere, but it seems odd to show "get" and not "put" request rates.

(collectd 5.7.1 on debian stretch, ceph luminous 12.2.1)


Thanks,

Sean
