Please help with regex trigger

[Carl Fortin]

I'm trying to make this trigger work with a regex:

I am using a UserParameter action that sends the following to Zabbix server:

PJSIP/U_3820-0001faf7 UnixTime:1438

I would like my trigger to return a problem if UnixTime is greater than 30.

Here's what I have so far:

{192.168.0.56:asterisk_check_stuck_channel.regexp( "UnixTime:.*$")}>30


It is not working.

Any help will be greatly appreciated

Hello!

Please, pay attention that regexp() in trigger expression will return either 0 or 1 as per the documentation: https://www.zabbix.com/documentation...gers/functions

Is your item a text that contain all the string "PJSIP/U_3820-0001faf7 UnixTime:1438" or a numeric that contain only "1438"? Wouldn't it be more convenient to store only numeric value and write triggers based off it?

My item is a text that contains the whole string. I'd like to keep it that way because I want my action to send me an email containing the PJSIP/U_3820-0001faf7 part. Is there any function to cut part of the string and keep only the numeric value?

What about regsub? https://www.zabbix.com/documentation...acro_functions

Is there any function to cut part of the string and keep only the numeric value?

Sorry, even if there is, I cannot find it.

My item is a text that contains the whole string. I'd like to keep it that way because I want my action to send me an email containing the PJSIP/U_3820-0001faf7 part.

I can only offer to write down this text part in action message itself.

I ended up using this that work for me:

{192.168.0.56:asterisk_check_stuck_channel.regexp( "UnixTime: (3{1}[0-9]{1}|[0-9]{3}|[0-9]{4}|[0-9]{5})$")}=1

It will trigger a problem if a numeric value is between 30 and 99999.
