Trigger function nodata()

[Rid]

Hi together,

a cronjob on a server is running every first day of a month at 06:00 am and sending value to zabbix server. I want to trigger an alert if I don't receive the value at this time or day.
Currently I am using the nodata() trigger: cronjob.times.processing.nodata(30d)}=1

It's an item trapper.

How can I configure the trigger to expect a value at every first day of a month at 06:00 or day? The problem with the trigger above is, that a month can have 28 or 31 days.

Hope someone out there that can help.

best regards
Stefano

Add dayofmonth function to the trigger and set nodata to 7 hours:

{cronjob.times.processing.nodata(7h)}=1 and {cronjob.times.processing.dayofmonth()}=1

wow, that was fast. Thank you!

At the first look it seems great, I will try it.

Wait, that will go wrong. It will alert at 14:00 even if you receive a value. :-D If you don't care that the alert will fire 7 hours after missing value set it to:

{cronjob.times.processing.dayofmonth()}=1 and {cronjob.times.processing.nodata(13h)}=1

But wouldn't it hit also twice, when I set it to 13h? Because if Zabbix Server receives the value at 6 am then it except the next value 13h later at that day. So it would fire an alert at 7 pm.

{cronjob.times.processing.nodata(18h)}=1 and {cronjob.times.processing.dayofmonth()}=1 and {cronjob.times.processing.time()}>060500

Haha, sorry, I messed it up. Take the expression of Semiadmin . :-)
