Windows log action problem

[shagma]

I have set up:

ITEM
Name: Application Log
Key: eventlog[Application]

Name: System Log
Key: eventlog[System]

TRIGGER
Name:Application Log ERROR
Expression: {Windows Logging:eventlog[Application]. logseverity( 4 ) }=4

Name: System Log ERROR
Expression: {Windows Logging:eventlog[System]. logseverity( 4 ) }=4

These are from Windows Logging template found on wiki so they should be fine unless i messed them up somehow.

Then i have actions:

Name: Event Application Info
Conditions: Trigger = "Application Log ERROR"
Trigger severity = "High"
Trigger value = "PROBLEM"

The Event System Info action is currently disabled.

The problem:

As long as I have Trigger = "Application Log ERROR" in conditions, Zabbix will not generate any e-mail. If I remove that condition, then, ofcourse, zabbix will e-mail both the application error event (which is fine) and another e-mail with whatever system log message was most recently logged (which I don't need).

How do I configure an action that sends notification only when a specific trigger is activated?

So i changed the conditions to only include:

Trigger description like "Application Log ERROR"
Trigger value = "PROBLEM"

Trigger description like "System Log ERROR"
Trigger value = "PROBLEM"

It now seems that i only get emails with actual eventlog errors. I then added some more servers, and new problem occurs. After just about 10 mins I get 40 emails, only the emails all contain info about the same error.

Is this how zabbix is supposed to work?
