Trigger count with a trapper value

[sbockelman]

I have a item defined as a trapper that stores the unixtime when an event happens.
ie:
key: test.trapper
Type: Numeric (unsigned)
Data type: Decimal
Units: unixtime

I am trying to set a trigger that uses .count that will let me know if there has been any values in the past 15 minutes. I have tried this:
{server:test.trapper.count(900)}>0

I have also tried:
{server:test.trapper.count(900,0,"gt")}>0

Neither work. Using .nodata does work, but does not allow me the fine grain detail I need.

The odd thing is that the trigger will report a problem initially, but will never become OK.

Are there any known issues with .count and trapper items?

I am running the latest 2.0.9

A trapper item's trigger gets only evaluated when a new trapper value is received. That explains why your trigger kicks in but never gets out of it's triggered state.

You would like to define a separate item as a normal (scheduled) item which checks your trapper item for .nodata or .count

Think I found a work around. I changed the trigger to:
{server:test.trapper.count(900)}>0&{server:test.tr apper.nodata(900)}=0

This forces zabbix to check for nodata and count it even if no data has been sent to the trapper.
