Hello,

I don't think this is a silly question!  I think it's really good.  I don't know the answer.

https://docs.microfocus.com/doc/Operations_Bridge_Manager/2023.05/OmptMeasurementThresholdhtml suggests:

"if VB Script or Perl Script is selected, select Filter using object name pattern if you want to use a pattern matching string to match the instance (or instances) for which you want to write specific rules. You must specify the pattern in the Object name matches field. Alternatively, select Filter using script and type a VB Script or Perl Script that filters the object instances. 
For a VB Script, set Rule.Status = True if the object instance matches the condition. Otherwise set Rule.Status = False.
For a Perl Script, set $Rule->Status(TRUE); if the object instance matches the condition. Otherwise set $Rule->Status(FALSE);."

So there are two methods - object name and filter script.

And the pattern matching is described here:

https://docs.microfocus.com/doc/Operations_Bridge_Manager/2023.05/PatternMatchingDetailshtml

So I tested using a logfile policy "magic bottle" which is how I always test these regular expressions to see if this works:

...which was:

/boot|/opt/app|/home|/var/log|/var/tmp

Could you please try adding this as a policy parameter:

Sorry, but I've not had a chance to test.

Thanks.

So I should say, this uses object name as a policy parameter containing /boot|/opt/app|/home|/var/log|/var/tmp which are the file systems OR'd together.  Sorry, I was multi-tasking earlier.  Something I don't do too well....
