trigger for system.cpu.load

[ggs_admin]

Hello everyone,

I have 3 items for checking load on the server:



Any of these items is working properly,
I have configured the 2 triggers:




but sometimes I'm receiving the warning / high types of the issue where seeing the UNKNOWN values



Any ideas why it is getting the "UNKNOWN" values?
I think that it's a bug of Zabbix since it has triggered when a load was 7.13 (it's value avg1) but it should be triggered once it bigger than 16

What is there on "Operational data" field in trigger config? Something like {ITEM.LASTVALUE2} and {ITEM.LASTVALUE3} etc? As you are using just one item for trigger, there is no values for other macros but {ITEM.LASTVALUE1}.

Operational data shows you current value there... not the "at the time of event" value. as per documentation

Operational data

Operational data allow to define arbitrary strings along with macros. The macros will resolve dynamically to real time data in Monitoring → Problems. While macros in the trigger name (see above) will resolve to their values at the moment of a problem happening and will become the basis of a static problem name, the macros in the operational data maintain the ability to display the very latest information dynamically. The same set of macros is supported as in the trigger name.

Hello,

Are you are absolutely right. It has the following:

Load averages: ({ITEM.LASTVALUE1} {ITEM.LASTVALUE3} {ITEM.LASTVALUE4}), # of CPUs: {ITEM.LASTVALUE2}



So how can I get it working with other LASTVALUE3 and LASTVALUE4?

should simply change this template from "system.cpu.load[all,avg1].avg(1m)}>20 " to something like "system.cpu.load[all,avg1,avg5,avg15].avg(1m)}>20" is it right?
Exactly, I have tried to use system.cpu.load[all,avg1,avg5,avg15] or system.cpu.load[avg1,avg5,avg15] but it doesn't work in Zabbix 5.0
Or should I create separate triggers for avg5, and avg15 ?

What are you trying to achieve? Listing of 4 latest values of the item? It does not work like that....
If you are using only one item in your trigger, then you can use only {ITEM.LASTVALUE} or {ITEM.LASTVALUE1}. If you use 2 items in your trigger expression, you can use {ITEM.LASTVALUE1} and {ITEM.LASTVALUE2}...

Thanks for clarifying.
ideally, I want to get the alert something like that
load averages: 20.58, 18.50, 17.48 where the 20.58 it's value of the avg1, 18.50 it's value of the avg5, and 17.48 it's value of the avg15.

So in that case, I should add to the expression other checks for avg5 and avg15, is it right?

So I have changed my trigger to the following



Let's see if it solves this issue

Hello,

I can confirm that it is working as expected. Thanks cyber

Well, lets say it is almost working. Or mostly working. Don't forget, you introduced 2 other conditions to expression with OR statement, so it can trigger, when any of 3 is true. If you want this to work only, when avg1 is over limits, but to show out also avg5 and avg15, you should probably use "avg1>20 and avg5 >=0 and avg15>=0". In such case, 2nd and 3rd part of expression are anyway true and don't really affect end result. But as they are present in expression, you can use their values in trigger name, opdata etc.

Thanks for that point, but I really need to get it alerting when any of these values is more than 20
