Zabbix plugin for ceph-mgr

Zabbix plugin for ceph-mgr

[Wido den Hollander]

Hi,

After looking at the documentation [0] on how to write a plugin for ceph-mgr I've been playing with the idea to create a Zabbix [1] plugin for ceph-mgr.

Before I start writing one I'd like to check if I'm thinking in the right direction.

Zabbix supports Items and Triggers. Triggers are based on Items's values. A Item could be from the type 'Trapper' where a application can simply send key=value pairs, for example:

my.host.name ceph.health HEALTH_OK
my.host.name ceph.osd.up 499
my.host.name ceph.osd.in 498

A simple ceph-mgr module could do:

def serve(self):
  while True:
    send_data_to_zabbix()
    time.sleep(60)

Now, would that be a sane plugin for ceph-mgr or is this something you shouldn't put in the mgr? To me it seems like a good place since it already has all the data present.

Ok, good! I'll take a stab at it and also include a Zabbix template (XML) so users can easily adopt it.

Sorry for posting this message a couple of times. Spamfilters were fighting me, greylisting and such, but suddenly the messages came through. My apologies!

This is absolutely a sane thing to put in the mgr (and include in the
main ceph tree) -- go for it!

    time.sleep(60)

Now, would that be a sane plugin for ceph-mgr or is this something you shouldn't put in the mgr? To me it seems like a good place since it already has all the data present.
