Zabbix Module
|
|
=============
|
|
|
|
The Zabbix module actively sends information to a Zabbix server like:
|
|
|
|
- Ceph status
|
|
- I/O operations
|
|
- I/O bandwidth
|
|
- OSD status
|
|
- Storage utilization
|
|
|
|
Requirements
|
|
------------
|
|
|
|
The module 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.
|
|
|
|
Dependencies
|
|
^^^^^^^^^^^^
|
|
Installing zabbix_sender can be done under Ubuntu or CentOS using either apt
|
|
or dnf.
|
|
|
|
On Ubuntu Xenial:
|
|
|
|
::
|
|
|
|
apt install zabbix-agent
|
|
|
|
On Fedora:
|
|
|
|
::
|
|
|
|
dnf install zabbix-sender
|
|
|
|
|
|
Enabling
|
|
--------
|
|
You can enable the *zabbix* module with:
|
|
|
|
::
|
|
|
|
ceph mgr module enable zabbix
|
|
|
|
Configuration
|
|
-------------
|
|
|
|
Two configuration keys are vital for the module to work:
|
|
|
|
- zabbix_host
|
|
- identifier (optional)
|
|
|
|
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.
|
|
|
|
When the *identifier* parameter is not configured the ceph-<fsid> of the cluster
|
|
will be used when sending data to Zabbix.
|
|
|
|
This would for example be *ceph-c4d32a99-9e80-490f-bd3a-1d22d8a7d354*
|
|
|
|
Additional configuration keys which can be configured and their default values:
|
|
|
|
- zabbix_port: 10051
|
|
- zabbix_sender: /usr/bin/zabbix_sender
|
|
- interval: 60
|
|
- discovery_interval: 100
|
|
|
|
Configuration keys
|
|
^^^^^^^^^^^^^^^^^^^
|
|
|
|
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 zabbix config-set <key> <value>
|
|
|
|
For example:
|
|
|
|
::
|
|
|
|
ceph zabbix config-set zabbix_host zabbix.localdomain
|
|
ceph zabbix config-set identifier ceph.eu-ams02.local
|
|
|
|
The current configuration of the module can also be shown:
|
|
|
|
::
|
|
|
|
ceph zabbix config-show
|
|
|
|
|
|
Template
|
|
^^^^^^^^
|
|
A `template <https://raw.githubusercontent.com/ceph/ceph/master/src/pybind/mgr/zabbix/zabbix_template.xml>`_.
|
|
(XML) to be used on the Zabbix server can be found in the source directory of the module.
|
|
|
|
This template contains all items and a few triggers. You can customize the triggers afterwards to fit your needs.
|
|
|
|
|
|
Multiple Zabbix servers
|
|
^^^^^^^^^^^^^^^^^^^^^^^
|
|
It is possible to instruct zabbix module to send data to multiple Zabbix servers.
|
|
|
|
Parameter *zabbix_host* can be set with multiple hostnames separated by commas.
|
|
Hostnames (or IP addresses) can be followed by colon and port number. If a port
|
|
number is not present module will use the port number defined in *zabbix_port*.
|
|
|
|
For example:
|
|
|
|
::
|
|
|
|
ceph zabbix config-set zabbix_host "zabbix1,zabbix2:2222,zabbix3:3333"
|
|
|
|
|
|
Manually sending data
|
|
---------------------
|
|
If needed the module can be asked to send data immediately instead of waiting for
|
|
the interval.
|
|
|
|
This can be done with this command:
|
|
|
|
::
|
|
|
|
ceph zabbix send
|
|
|
|
The module will now send its latest data to the Zabbix server.
|
|
|
|
Items discovery is accomplished also via zabbix_sender, and runs every `discovery_interval * interval` seconds. If you wish to launch discovery
|
|
manually, this can be done with this command:
|
|
|
|
::
|
|
|
|
ceph zabbix discovery
|
|
|
|
|
|
Debugging
|
|
---------
|
|
|
|
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 module will print various logging
|
|
lines prefixed with *mgr[zabbix]* for easy filtering.
