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 + +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/9c54334b615362e0a60442c2f41849ed630598ab/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. +Hosnames (or IP adderesses) 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. + +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.
