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 or dnf.

On Ubuntu Xenial:

apt install zabbix-agent

On Fedora:

dnf install zabbix-sender


You can enable the zabbix module with:

ceph mgr module enable zabbix


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

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 set <key> <value>

For example:

ceph config-key set mgr/zabbix/zabbix_host zabbix.localdomain
ceph config-key set mgr/zabbix/identifier


Should you want to debug the Zabbix module increase the logging level for ceph-mgr and check the logs.

    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.
