Zabbix plugin
|
|
|
|
|
=============
|
|
|
|
|
|
|
|
|
|
The Zabbix plugin actively sends information to a Zabbix server like:
|
|
|
|
|
|
|
|
|
|
- Ceph status
|
|
|
|
|
- I/O operations
|
|
|
|
|
- I/O bandwidth
|
|
|
|
|
- OSD status
|
|
|
|
|
- Storage utilization
|
|
|
|
|

|
|
|
|
|
The plugin requires that the *zabbix_sender* executable is present on *all*
|
|
|
|
|
machines running ceph-mgr. It can be installed on most distributions using
|
|
|
|
|
the package manager.

Installing zabbix_sender can be done under Ubuntu or CentOS using either apt
|
|
|
|
|

Enabling

|
|
--------

2017-06-27 13:49:03 +00:00
|
|
|
|
|
|
|
|
Add this to your ceph.conf on nodes where you run ceph-mgr:
|
|
|
|
|
|
|
|
|
|
::
|
|
|
|
|
|
|
|
|
|
[mgr]
|
|
|
|
|
mgr modules = zabbix
|
|
|
|
|
|
|
|
|
|
If you use any other ceph-mgr modules, make sure they're in the list too.
|
|
|
|
|
|
|
|
|
|
Restart the ceph-mgr daemon after modifying the setting to load the module.
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
Configuration
|
2017-07-21 03:09:05 +00:00
|
|
|
-------------
|
2017-06-27 13:49:03 +00:00
|
|
|
|
|
|
|
|
Two configuration keys are mandatory for the module to work:
|
|
|
|
|
|
|
|
|
|
- mgr/zabbix/zabbix_host
|
|
|
|
|
- mgr/zabbix/identifier
|
|
|
|
|
|
|
|
|
|
The parameter *zabbix_host* controls the hostname of the Zabbix server to which
|
|
|
|
|
*zabbix_sender* will send the items. This can be a IP-Address if required by
|
|
|
|
|
your installation.
|
|
|
|
|
|
|
|
|
|
The *identifier* parameter controls the identifier/hostname to use as source
|
|
|
|
|
when sending items to Zabbix. This should match the name of the *Host* in
|
|
|
|
|
your Zabbix server.
|
|
|
|
|
|
|
|
|
|
Additional configuration keys which can be configured and their default values:
|
|
|
|
|
|
|
|
|
|
- mgr/zabbix/zabbix_port: 10051
|
|
|
|
|
- mgr/zabbix/zabbix_sender: /usr/bin/zabbix_sender
|
|
|
|
|
- mgr/zabbix/interval: 60
|
|
|
|

Configuration keys
|
|
|
|
|
^^^^^^^^^^^^^^^^^^^
|
2017-06-27 13:49:03 +00:00
|
|
|
|
|
|
|
|
Configuration keys can be set on any machine with the proper cephx credentials,
|
|
|
|
|
these are usually Monitors where the *client.admin* key is present.
|
|
|
|
|
|
|
|
|
|
::
|
|
|
|
|
|
|
|
|
|
ceph config-key put <key> <value>
|
|
|
|
|
|
|
|
|
|
For example:
|
|
|
|
|
|
|
|
|
|
::
|
|
|
|
|
|
|
|
|
|
ceph config-key put mgr/zabbix/zabbix_host zabbix.localdomain
|
|
|
|
|
ceph config-key put mgr/zabbix/identifier ceph.eu-ams02.local
|
|
|
|
|
|
|
|
|
|
Debugging
|
2017-07-21 03:09:05 +00:00
|
|
|
---------

|
|
|
|
|
|
|
|
Should you want to debug the Zabbix module increase the logging level for
|
|
|
|
|
ceph-mgr and check the logs.
|
|
|
|
|
|
|
|
|
|
::
|
|
|
|
|
|
|
|
|
|
[mgr]
|
|
|
|
|
debug mgr = 20
|
|
|
|
|
|
|
|
|
|
With logging set to debug for the manager the plugin will print various logging
|
|
|
|
|
lines prefixed with *mgr[zabbix]* for easy filtering.
|
|
|
|
