Trigger stopped working

[grantav]

Hi Guys

I have a trigger which has normally work well in the past (almost every second day) but did not work last night for some reason when it should have.

The trigger looks for when an average value (over 120 seconds) drops below a certain level(680) either before 08:30 or after 16:30 on any given day.

{Sim Stats:IntSim_AGGREGATE.sh[].avg(120)}<680&({Sim Stats:IntMin_AGGREGATE.sh[].time(0)}>163000|{Sim Stats:IntMin_AGGREGATE.sh[].time(0)}<083000)

I can see from event history on that specific trigger that it has fired between the 00:00 to 08:30 and the 16:30 to 23:59 periods so I am pretty sure the expression is correct.

There are no scheduled maintenance periods.

Does anyone know why something like this would occur and how I could correct it?

Regards
G

Found the issue. The data is provided via a text file which is read by Zabbix. The text file is updated by a cronjob which runs a script.

The issue was an assumption made in the script.
