Help setting up log trigger

[blastik]

Hi folks,

I have setup an item like this:

log["C:\whatever\Logstest.txt",,100]

But i need help setting up the trigger. I've tried to search around in the forum and also check the documentation but i cannot get it to work. I want to trigger an alert when a trace like the one below is recorded at the log:

2015-05-15 11:16:23.8370|Error|1556|1|Unregistering errored channel ...

And reset the trigger status to OK when the following trace comes up:

2015-05-15 11:10:57.1960|Info|3420|31|Channel whatever started

Any ideas?

Thanks a lot!
D.

See Trigger hysteresis

See Trigger hysteresis

So I've tried

{TRIGGER.VALUE}=0 and {host:log["C:\whatever\Logstest.txt",,100].str(|Error|1556|1|Unregistering errored channel)} or {TRIGGER.VALUE}=1 and {host:log["C:\whatever\Logstest.txt",,100].str(|Info|3420|31|Channel * started)}

but apparently is not making the trick... Any thoughts?

This is how I do it:

Item:
log[/var/log/system.log,"FAILED"]


Trigger Expression:
{ServerName:log[/var/log/system.log,"FAILED"].str("FAILED",1)}=1


But I do not know how to make trigger status to ok.

Wow, I have just posted a similar question

How to set the trigger back to OFF

[BDiE8VNy]

One needs to use at least one time-based function within the trigger expression to get a trigger evaluated when no new item value(s) occur.
