Yes, it is there
Thanks for pointing it.

But there is another question stay open:
Why it add already added services?
For example there is Service Group A. In this service group is services AB, AC, AD

I did Recurring Downtime for Servicegroup A for every monday at 2AM.

I can see this in Scheduled Downtime->Scheduled Service Downtime, everything is fine.

After 1 hours I see that is another additional downtimed services AB,AC,AD with different "Entry Time" but for same "Start Time End Time Type Duration".

Regards,

You can overlap downtime, as dictated by the Scheduled Downtime section in:

http://nagios.sourceforge.net/docs/3_0/downtime.html

It says:
If you schedule overlapping periods of downtime for a host or service (in this case the periods were 7:40pm-9:30pm and 9:20pm-1:30am), Nagios will wait until the last period of scheduled downtime is over before it allows notifications to be sent out for that host or service. In this example notifications would be suppressed for host A until 1:30am Tuesday morning.
I believe this is what you are referring to correct? If not I apologize.

No, I did not adding anything additional.
I do just Recurring Downtime for Service Group.
First look - fine.
But after hours the same services coming in again and again.
I can try to add it now and next time will provide the screen shot.

Thanks

I think I found issue in /usr/local/nagiosxi/cron/recurringdowntime.pl.

I did changes in

Code: Select all

 sub readdowntime2
.

Because in

Code: Select all

 sub schedule_servicegroup($$$$$$) {
in here:

Code: Select all

	foreach $sr ( @{$servicegroups{$sg}} ) {
		print "$sr:$s\n";
it has following output:

Code: Select all

Scheduling servicegroup Prod_SC_CitrixFarm
SQ5VPMXENAPP003;Citrix_App_MetaFRAME_Load_Level:1368683940
It has ";" instead of ":"

But in readdowntime2 it add following string:

Code: Select all

SQ5VPMXENAPP003:Citrix_App_MetaFRAME_Load_Level:1368683940

Here is my readdowntime2 sub (the bold is my changes):

Code: Select all

sub readdowntime2 {
	my($hd,$sd,$start,$a);
	my($f) = $DOWNDAT;
	my($dtid);
	$f = $STATUSDAT if(!$f or ! -r $f);
	$f = $RETENTIONDAT if(!$f or ! -r $f);
	if(!$f or ! -r $f) { readdowntime; return; }
	print "Reading downtime information from $f ..." if($DEBUG);
	$a = 0;
	open DD, "<$f" or return;
	while ( <DD> ) {	
		if( /^\s*hostdowntime/ ) {
			$a = 1; $hd = $dtid = ""; $start = 0;
			print "Hostdowntime found\n";
		} elsif( /^\s*servicedowntime/ ) {
			$a = 2; $hd = $sd = $dtid = ""; $start = 0;
			print "Servicedowntime found\n";
		} elsif( $a and /^\s*}/ ) {
			if($a == 1) {
				$downtime{"$hd:$start"} = 1;
				print "Adding host $hd:$start:$dtid\n" if($DEBUG);
			} elsif($a == 2) {
				$downtime{"$hd;$sd:$start"} = 1; # here I made changes, instead of ":" I added ";"
				#$downtime{"$hd:$sd:$start"} = 1;
				print "Adding service $hd:$sd:$start:$dtid\n" if($DEBUG);
			}
			$a = 0;
		} elsif( $a ) {
			if( /^\s*host_name\s*=\s*(.*\S)/ ) { $hd = $1; }
			elsif( /^\s*service_description\s*=\s*(.*\S)/ ) { $sd = $1; }
			elsif( /^\s*start_time\s*=\s*(\d+)/ ) { $start = $1; }
			elsif( /^\s*downtime_id\s*=\s*(\d+)/ ) { $dtid = $1; }
		}
	}
	close DD;
	print "Done.\n" if($DEBUG);
}

So, additional information.

I found following.
Some how in this variable "@{$servicegroups{$sg}}" the collect services twice from the same service group.

I did couple of changes, will provide script tomorrow after testing.

Thanks

Perfect.
it works us expected - no any doubled services from Recc Down timed service group.
Of course - most of added line is for debug purposes.


This issue happened when we have migrated from 2011 to 2012 version.
In 2011 everything was fine, without any issues.
