Using the value of a calculated item in a iregexp type function.

[Dominic123]

Hello everyone. I'm new to this forum and to zabbix also. I'm curently Learning how all of this works. So far so good, everything is fine. Exept..

I want to have certain conditions in a trigger that evaluate if we are during a work day and Inside of the opening hours. I can't use user created macros or hard coded values for the workdays because my zabbix server monitors a bunch of interfaces that have different work days and opening hours. I managed to tell zabbyx what are those values using a zabbix trapper item. What i'd like to do is simply use a calculated item or even conditions Inside of a trigger to compare the value of that trapper item to a dayofweek function.

For example, I'd like to use a calculated item like that:

iregexp("item.work.days","item.curentday")

Zabbix will interpret the second argument ("item.curentday") as a string while I would like it to interpret it as the value of that item.

Has anyone ever encountered that problem?

Thanks for your help.

Dominic

Hello Dominic123!

Indeed, iregexp function's second value is either time in seconds or Nth value number as per the documentation: iregexp (pattern,<sec|#num>)

dayofweek, on the other hand, operates with the days, so if you do something like item.curentday = (dayofweek(0)=1) in trigger expression, it might work.

For example, I quickly added a Zabbix trapper item.current.day, sent it value "2" and added a trigger expressions:

{<hostname>:item.current.day.last()}={<hostname>:item.current.day.dayofweek()}

It fired. You just need to set your own logic in a similar trigger.
