how to do "contain" in trigger expression

[choun]

Hi, I have the below trigger expression which works great. However, if i want to add one more condition which is when {#POVALUE} contains the word "chrome" (#POVALUE could be chrome, chrome.1, chrome.2...etc,) how can I do that?
min(/TemplateA/op.depend.item[{#POVALUE},ws],60s)> 15
min(/TemplateA/op.depend.item[{#POVALUE},ws],60s)> 15 and {#POVALUE} = "chrome" ( this works but it has to match the exact word "chrome" )
i tried
1. {#POVALUE} like "chrome"
2. {#POVALUE} ~ '.*chrome.*'
..........etc
all gave me the error similar to the below
Invalid parameter "/1/expression": incorrect expression starting from "~ '.*chrome.*'


Please help!

Look at example 6 of this page: https://www.zabbix.com/documentation...ers/expression

Hi Brambo,

Thanks for your reply. i've tried your post but it didnt work. In the Find() example listed on the site, find(/example.example.com/agent.version,,"like","beta8")=1, you need to put item in the first part(in this case, it's /example.example.com/agent.version). However, in my case, I want to put a value (POVALUE) which returned by my external script instead of the item. So my express should look something like "min(/TemplateA/op.depend.item[{#POVALUE},ws],60s)> 15 and find({#OPVALUE},,"like","chrome")=1

instead of "like, I tested "{#IVALUE} = "chrome" , and it worked. If i'm sure {#IVALUE} returned the string I expected. However, thats not exactly what I want. instead of " absoluate match ", I would like to use partial match such as " contain" or "like" in my case.

Zabbix gave the error " Invalid parameter "/1/expression": incorrect expression starting from "find({#OPVALUE},,"like","chrome")=1".


Please help

What would be the point of that trigger?

[choun]

the trigger will only get alerted when the below 2 conditions are met
1. min(/TemplateA/op.depend.item[{#POVALUE},ws],60s) > 15 ( it will verify if the process's working set value in perfmon is > 15, ws is short for working set)
2. find({#OPVALUE},,"like","chrome")=1 (it will verify if the string of {#OPVALUE} contains the word "chrome" , while {#OPVALUE} could be any Windows process name, such as explore , chrome, firefox...etc)

any help is much appreciated.

I think you should either look into how to build a trigger and or use the select option in the create trigger section.
The code you supply in example 2 cant work at all.
And as code example 2 cant work it would suprise me you make an error in example 1 as well.
Start using the add button next to the expression field and create your expression from there:

So you are ready to create a whole lot of triggers based on LLD, but only one of them will ever work? You better use LLD overrides to create only, what you need and do not create useless stuff. Or just discover those what you need, not "everything"...
