User-Defined Parameters

UserParameters UserParameters

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 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
