zabbix_kmod - retrieve loaded kernel modules for zabbix.
zabbix_kmod [option]
This command support the use of the included template in zabbix.
In order for the command to be useful to zabbix, a number of installation steps need to be done.
The command needs to be installed on one or more zabbix agents. The default location referenced in all files in this repository is:
/usr/local/bin/zabbix_kmod
There is no configuration required for this command. The command will detect which kernel modules are loaded and collect them.
It is best to run the command from cron. The user running the command needs enough privileges to read the configuration file.
In order to create statistics the command needs to be run with the getdata option:
/usr/local/bin/zabbix_kmod getdata
The output data of the command will be stored in:
/tmp/zabbix-kmod
A useful crontab entry would be:
* * * * * /usr/local/bin/zabbix_kmod getdata
Now that the information is being gathered, the zabbix agent needs to be made aware of how the information can be retrieved. A configuration file is available in the repository and should be installed at:
/etc/zabbix/zabbix_agentd.d/zabbix_agent-kmod.conf
After the configuration has been added, reload the agent
systemctl restart zabbix-agent
The final step should be taken server side. In order to monitor the data a new template needs to be imported.
- Open the zabbix webinterface
- Go to Configuration -> Templates
- Choose Import
- Choose browse and select the
template-kmod.xmlfile in the file browser. - Make any require changes to rules
- Select Import
The template is now available. In order to configure it for a host with a zabbix agent that has been configuratie with the command follow the steps below.
- Open the zabbix webinterface
- Go to Configuration -> Hosts
- Select the name of the host to configure
- Go to templates
- Choose Template Kernel modules at the Link new templates box
- Choose Add
- Choose Update
Zabbix should now start collecting data.
