How can i create trigger threshold 90% for CPU utilization?

[khoi-thinh]

Hi everyone,
I'm totally new to zabbix.
I installed zabbix sever in my own Linux server and it worked fine.
I don't know much so when i created new host, i added all template Zabbix Server, OS Linux... and now my graph is like this.




I want to find a way how to make a trigger and send to my email when CPU utilization is over 90%.
Can someone guide me with details, step-by-step? Because i didn't find any good tutorials on Internet.
Much appreciated!

Hey mate,

First and foremost go to Configuration > Templates! Select the OS Linux template from there and navigate to Items - Items are essentially the keys that you give to zabbix - more on that from https://www.zabbix.com/documentation...l/config/items

In your case you would want to create a trigger for the CPU idle time item so you would know when the CPU is not idling. To do that make a new trigger under the trigger section of the same template and give it a value of

{Template OS Linux:system.cpu.util[,idle].avg(1m)}<10

When you create that trigger make sure you give it a name and the line above should go to expression part of the trigger conf.
More about triggers: https://www.zabbix.com/documentation...onfig/triggers


And now you would want it to send out emails to you!
Navigate to actions tab in your zabbix installation and create a new action!

More on that can be found on https://www.zabbix.com/documentation...cations/action

After that you should be golden.

Hope that helps!
