Re: Threshold SPAN and persistent-alarms is not working

Hi Francois,

After checking the meta file and logMonitor I have found that the SPAN
is working. 

If I clear all the .meta files. I can see that they is 2 hour delay
before the alarm start to run my script. Now the persistent-alarms is
still not working. I have made the changes as you said. Where in the
script does it check for persistent-alarms value.

Hello Naveen,

That one is for me...

If not, here is how to check you meta processing:

- check your meta files in the data portion of your config tree to see 
if they are not corrupted.
- check the output from logMonitor:

	You should always see this, if your monitor test failed :
LogMonitor("$name -  $mt - $Threshold failed.");
Then depending on if there is no span event: LogMonitor("Triggering
alarm for $Threshold.");
Or if there is a span event: LogMonitor("Triggering a span event for
$Threshold.");

A span event is when the time period = (your span value *
rrdpollinginterval).

Though I think the bug is here: 

  241 if ($span && $mt < ($time - ($spanlength * $rrdpollinterval) -
90)) {
  242                         $spanfail = 1;
  243                 }

I think the $span && $mt is being evaluated together, then the < is 
evaluated...

The logic should have been like this:

  241 if ($span && ($mt < ($time - ($spanlength * $rrdpollinterval) -
90))) {
  242                         $spanfail = 1;
  243                 }

I am wrong in my though process. If that is what it is, it would explain

why you would be getting repeated span events. When in reality your are 
just getting a regular threshold failure.

Change the line and see if it fixes your problem.Depending on the 
version of HandleTarget.pm you have, the line number may differ.

Cheers,

Francois Mikus
