Trigger on no data change

[sspaise]

Hi all,

Firstly apologies if this has been asked before but I could not find a directly related thread.

I am trying to setup an item and trigger that will alert me if the data does not change for one week.

I have a command I am running on the server "invade agents" that produces a number based on the amount of "users" that are connected to the server.

I would like to setup a trigger to alert me if this does not change over a week. Could anyone please point me in the direction of how to do this?

Hey,

I'm not entirely sure if this is what you are looking for. But delta looks for the min() and max() in a period.

https://www.zabbix.com/documentation/2.0/manual/appendix/triggers/functions

So if your amount of users stays 10 for a whole week: min() = 10, max() = 10

delta = max()-min()
0 = 10-10
If 0 -> fire trigger.

{hostx:amountOfUsersKey.delta(1w)}=0

Hi jasperswaagman,

Thanks for the reply, I was eyeing this in the documentation earlier but couldn't work out if it would provide what I required, however it appears this should suit just fine.

I'll give this a try and let you know how it goes =)
