-==== 1 Extending Zabbix agents ==== 
- 
-This tutorial provides step-by-step instructions on how to extend the functionality of Zabbix agent with the use of a [[:​2.4/​manual/​config/​items/​userparameters|user parameter]]. 
- 
-== Step 1 == 
- 
-Write a script or command line to retrieve required parameter. 
- 
-For example, we may write the following command in order to get total number of queries executed by a MySQL server: 
- 
-  mysqladmin -uroot status|cut -f4 -d":"​|cut -f1 -d"​S"​ 
- 
-When executed, the command returns total number of SQL queries. 
- 
-== Step 2 == 
- 
-Add this command to agent'​s configuration file. 
- 
-Add the command to zabbix_agentd.conf:​ 
- 
-  UserParameter=mysql.questions,​mysqladmin -uroot status|cut -f4 -d":"​|cut -f1 -d"​S"​ 
- 
-**mysql.questions** is an unique identifier. It can be any string, for example, queries. 
- 
-Test this parameter by using [[:​2.4/​manual/​concepts/​get|zabbix_get]] utility. 
- 
-== Step 3 == 
- 
-Restart Zabbix agent. 
- 
-Agent will reload configuration file. 
- 
-== Step 4 == 
- 
-Add new item for monitoring. 
- 
-Add new item with Key=mysql.questions to the monitored host. Type of the item must be either Zabbix Agent or Zabbix Agent (active). 
- 
-Be aware that type of returned values must be set correctly on Zabbix server. Otherwise Zabbix won't accept them.
