How to configure custom monitoring scripts in Zabbix?
To set up custom monitoring scripts in Zabbix, follow these steps:
- Develop a monitoring script: Write a script in any programming language to gather the necessary monitoring data. The script can be a Shell script, a Python script, or a script in any other programming language. Make sure the script returns the appropriate output for Zabbix to parse and utilize.
- Copy the monitoring script to the host where the Zabbix agent is located. By default, the script directory for the Zabbix agent is located at /usr/local/share/zabbix/externalscripts/. You can place the script in that directory, or in any other location of your choice.
- Make sure the script has executable permissions. Use the chmod command to add executable permissions to the script, for example: chmod +x /usr/local/share/zabbix/externalscripts/script.sh.
- Go to the “Configuration” -> “Hosts” section in the Zabbix management interface, locate the host you want to monitor, and click on its name.
- Choose “Items” from the left menu on the host configuration page, then click on “Create Item” to make a new monitoring item.
- Fill in the following fields on the “Item” page.
- Name: Specify a name for the monitoring item.
- Key: The key is a unique identifier used to transfer data between the Zabbix agent and server. The format of the key is typically custom.script[script.sh], where script.sh is the name of your script.
- Category: Choose the appropriate type based on the data output of your script. For example, if the script outputs numbers, select “Numeric.”
- Update interval: determine how often the monitoring item is updated.
- Application: Choose an application for monitoring items to better organize and categorize them.
- In the “Preprocessing” tab of the “Item” page, you can define any preprocessing steps to transform, filter, or process the output data of the script. This is optional and can be configured according to your needs.
- Click on “Add” to save the monitoring item configuration.
Once the above steps are completed, Zabbix will start collecting and processing the data generated by your custom monitoring scripts. You can view the data of the monitoring items on the “Monitoring” -> “Latest data” page.
