Help with trigger with count

[andvsilva]

Hello everyone.

I`m having some trouble with trigger with my Zabbix 5.0.

I create a item to check if the process is running in my CentOS like this:

proc.num[node,,,webserver.coffee]

So, I create a trigget to check if the process is running and only one process not more than 1.

-Trigger problem:

{Template_Teste: proc.num[node,,,webserver.coffee].count(#3)}<{$PROC_MIN_DASHMONITOR}
or {Template_Teste: proc.num[node,,,webserver.coffee].count(#3)}>{$PROC_MAX_DASHMONITOR}

- Trigger OK:

{Template_Teste: proc.num[node,,,webserver.coffee].last(#1)}={$PROC_MIN_DASHMONITOR}

This macros:
{$PROC_MIN_DASHMONITOR} = 1
{$PROC_MAX_DASHMONITOR} = 1

I want to check in the last 3 times if the process is running on One unique process.

Someone can help me?

I read the documentation in Zabbix Page but I don't figure out what I'm doing wrong.

you not need OK trigger, just PROBLEM with ( max(#3) >1 or min(#3)<1 )

All right Hamardaban, thanks. I change my check using one Unique host to check the value in the two other host. But I still need help with my trigger. Because I'm trying to Trigger only after 3 consecutive attempts with failure. But now I'm checking if the return value is 'OK' if the return will different of this I will trigger but only after 3th attempt.

For example:

{Template_Teste: proc.num[node,,,webserver.coffee]..count(#3,"^(?!OK).+","regexp")}=3}

This RegEx "(?!OK).+" I'm using to certify the return value doesn't starts with "OK".

But I'm certainly doing something wrong.
