User-Defined Parameters
Video Lecture
Description
I create several examples of user-defined parameters in Zabbix.
Example 1
Starting as simple as possible.
I create an item to check isalive
Inside the Zabbix agent configuration file, on the host that will run the user parameter, I add,
UserParameter=isalive,echo 1
I save it, then I test it using,
zabbix_agentd -t isalive
I then restart the Zabbix agent process,
sudo service zabbix-agent restart
I then add a new item to my host with
| Property | Value |
|---|---|
| Name | Is Alive |
| Key | isalive |
| Type of information | Numeric (unsigned) |
I go to Monitoring ⇾ Latest Data and wait for it to appear.
Example 2
And now for something a bit more complicated, and that is Flexible User Parameters.
Inside the configuration file I add,
UserParameter=isalive[*],echo $1
I can test it using
zabbix_agentd -t isalive[123]
Restart the Zabbix agent process,
sudo service zabbix-agent restart
The item inside Zabbix Server has,
| Property | Value |
|---|---|
| Name | Is Alive |
| Key | isalive[123456] |
| Type of information | text |
Example 3
And now, I convert an existing system.run command to a user parameter.
The script called in this system.run command is outlined in lecture Check SSL Certificate Expiry on Websites using Custom Script and system.run
Inside the configuration file I add,
UserParameter=checkssl[*],/home/zabbix/checkssl.sh $1 $2
I can test it using
zabbix_agentd -t checkssl[example.com,443]
Restart the Zabbix agent process,
sudo service zabbix-agent restart
The item inside Zabbix Server has,
| Property | Value |
|---|---|
| Name | Check SSL example.com |
| Key | checkssl[example.com,443] |
| Type of information | Numeric (unsigned) |
