Application Trigger

How would I set up a simple trigger to grep for a process every 5 mins?

Greetings,

How would I set up a simple trigger to grep for a process every 5 mins?

First, you need to create an item that checks the process. Something like;

proc.num[<Process Name>]

This item should have a periodicity of about 30 seconds or 1 minute. Once that is created, you can create a trigger that would look something like;

{HOST:procnum[<Process Name>].min(#5)}<1}

This will trigger if <Proccess Name> is not found to be running on server HOST any time over the last 5 checks of the item.

Why do I keep getting this error:

Incorrect trigger expression. Incorrect host is used.

My Bad,,, I had a typo in the string. But now I get this error

Expression [{RESHP36roc.num[ibmslapd].min(#5) }<1}] does not match to [server:key.func(param)]

[James Wells]

does not match to [server:key.func(param)]

Do you have this item defined for that host? In this case, your host is reshp36 and the item is proc.num[ibmslapd]

Is there an extra space before the } ?

It looks like there is an extra bracket at the end of the expression. For every closed bracket, there must be an open bracket somewhere. The correct expression should be:

{RESHP36:proc.num[ibmslapd].min(#5)}<1

You are correct, and extra space was the culprit. Thanks everybody.
