User-Defined Parameters
Video Lecture
Description
I create several examples of using 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
name = is alive
key = isalive
type of information = numeric
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,
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 my previous lecture Check SSL Certificate Expiry on Websites using Custom Script and system.run
Inside the configuration file I add,
UserParameter=ssl.check[*],/home/zabbix/checkssl.sh $1 $2
I can test it using
zabbix_agentd -t ssl.check[example.com,443]
Restart the Zabbix agent process,
sudo service zabbix-agent restart
The item inside Zabbix Server has,
name = Check SSL example.com
key = ssl.check[example.com,443]
type of information = numeric
