FYI, 5 or even more years ago I was trying zabbix and when I noticed that when the monitored hosts increased, the load on the mysql server was increasing. Without being able to recall exactly what was wrong (I think every sample they did, was one insert statement), I do remember that I got quite an 'amateur' feeling of these guys. And when they apply 'strange logics' in one situation, they are likely to apply this more often elsewhere in their code. Then I moved to nagios. -----Original Message----- From: Wido den Hollander [mailto:wido@xxxxxxxx] Sent: dinsdag 27 juni 2017 11:09 To: ceph-users@xxxxxxxx Subject: Zabbix plugin for ceph-mgr 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 [2] 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) If for example the key ceph.health is != OK for >1h Zabbix could fire a trigger and send our an alert to an admin. 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. This way data is pushed to Zabbix instead of the need for polling the data and parsing JSON output of 'ceph -s' Wido [0]: http://docs.ceph.com/docs/master/mgr/plugins/ [1]: http://www.zabbix.com/ [2]: https://www.zabbix.com/documentation/3.0/manual/config/items _______________________________________________ ceph-users mailing list ceph-users@xxxxxxxxxxxxxx http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com _______________________________________________ ceph-users mailing list ceph-users@xxxxxxxxxxxxxx http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com
