Overview of this book

Nowadays, monitoring systems play a crucial role in any IT environment. They are extensively used to not only measure your system’s performance, but also to forecast capacity issues. This is where Zabbix, one of the most popular monitoring solutions for networks and applications, comes into the picture. With an efficient monitoring system in place, you’ll be able to foresee when your infrastructure runs under capacity and react accordingly. Due to the critical role a monitoring system plays, it is fundamental to implement it in the best way from its initial setup.

UserParameter is defined on the agent configuration file. Once it is configured, it is treated in the same way as all the other Zabbix agent items by simply using the key specified in the parameter option. To define a user parameter, you need to add something similar to the following to the agent configuration file:

UserParameter=<key>,<shell command>

Here, key must be unique and the shell command represents the command to execute. The command can be specified here inline and doesn't need to be a script, as shown in the following example:

UserParameter=process.number, ps -e |wc -l

In this example, the process.number key will retrieve the total number of processes on your server...
