Zabbix Module

The Zabbix module has not been supported since April 2020 at the latest. The upstream Ceph community in April 2024 developed procedures for installing Zabbix 2.

Discussion of the decisions around the lack of support for Zabbix can be found here: https://github.com/ceph/ceph-container/issues/1651

Installing zabbix-agent 2

The procedures that explain the installation of Zabbix 2 were developed by John Jasen.

Follow the instructions in the sections Ceph MGR Nodes, Ceph Cluster, and Zabbix Server to install a Zabbix server to monitor your Ceph cluster.

Ceph MGR Nodes

  1. Download an appropriate Zabbix release from https://www.zabbix.com/download or install a package from the Zabbix repositories.

  2. Use your package manager to remove any other Zabbix agents.

  3. Install zabbix-agent 2 using the instructions at https://www.zabbix.com/download.

  4. Edit /etc/zabbix/zabbix-agent2.conf. Add your Zabbix monitoring servers and your localhost to the Servers line of zabbix-agent2.conf:

    Server=127.0.0.1,zabbix2.example.com,zabbix1.example.com

  5. Start or restart the zabbix-agent2 agent:

    systemctl restart zabbix-agent2

Ceph Cluster

  1. Enable the restful module:

    ceph mgr module enable restful

  2. Generate a self-signed certificate. This step is optional:

    restful create-self-signed-cert

  3. Create an API user called zabbix-monitor:

    ceph restful create-key zabbix-monitor

    The output of this command, an API key, will look something like this:

    a4bb2019-XXXX-YYYY-ZZZZ-abcdefghij

  4. Save the generated API key. It will be necessary later.

  5. Test API access by using zabbix-get:

    Note

    This step is optional.

    zabbix_get -s 127.0.0.1 -k ceph.ping["${CEPH.CONNSTRING}","${CEPH.USER}","{CEPH.API.KEY}"

    Example:

    zabbix_get -s 127.0.0.1 -k ceph.ping["https://localhost:8003","zabbix-monitor","a4bb2019-XXXX-YYYY-ZZZZ-abcdefghij"]

    Note

    You may need to install zabbix-get via your package manager.

Zabbix Server

  1. Create a host for the Ceph monitoring servers.

  2. Add the template Ceph by Zabbix agent 2 to the host.

  3. Inform the host of the keys:

    1. Go to “Macros” on the host.

    2. Show “Inherited and host macros”.

    3. Change ${CEPH.API.KEY} and ${CEPH.USER} to the values provided under ceph restful create-key, above. Example:

      {$CEPH.API.KEY} a4bb2019-XXXX-YYYY-ZZZZ-abcdefghij
{$CEPH.USER} zabbix-monitor

  4. Update the host. Within a few cycles, data will populate the server.
