Trigger works once after saving then stops working

[mblake4u]

Hi,

I've got an item configured (which I can see in Latest Data):
log[C:\Progra~1\freeFTPd\freeFTPd-ftp.log,@FreeFTPd-REGEX1]

The global FreeFTPd-REGEX1 regex is simple:
.*FTP.*server.*started.*

I've then got a trigger defined:
{HOSTNAME:log[C:\Progra~1\freeFTPd\freeFTPd-ftp.log,@FreeFTPd-REGEX1].str(started)}=1

I've then got an action which sends an e-mail when the trigger is triggered.

The problem is that the trigger will work only sometimes - I can't predict when it'll work but it's usually after making a change to the trigger. If seems like once the trigger is in 'problem' state it won't trigger again until 'reset'?

TIA Michael

Zabbix never knows when your event "ends". You'll have a similar problem when triggering off of received traps. Change your trigger to something like:

({HOSTNAME:log[C:\Progra~1\freeFTPd\freeFTPd-ftp.log,@FreeFTPd-REGEX1].str(started)}=1)&({HOSTNAME:log[C:\Progra~1\freeFTPd\freeFTPd-ftp.log,@FreeFTPd-REGEX1].nodata(30)}=0)

and see what happens. This assumes that this event happens with a frequency greater than 30 seconds. If it happens more frequently, you'll lost some fidelity.

Out of curiosity, what version of the Windows agent are you using?

Thanks for the replies - it's working now and I'm getting a problem and ok e-mail each time it triggers.

I'm using version 1.8.3 of the agent and 1.8.2 server version.

Couple more questions - is there a reference for triggers? I've looked at the documentation but it doesn't seem to detail all the triggers.

Also can I modify the trigger so I only receive one e-mail (either the problem or ok e-mail)?

Cheers, Michael

This would be the best reference for Triggers:
