Nagiosgrapher

Some hints and comments about the usage of the plugin with Nagiosgrapher

1. plugin name

   Beware that if you are using Nagiosgrapher, the tool is not able to distinguish between check_procs and check_procs_multi (since it looks for PROCS in the plugin name).

   To avoid the problem you can just rename the name of the plugin in the output:

   $ check_procs_multi [arguments] | sed -e 's/CHECK_PROCS_MULTI/MULTIPROC/g'
   

2. adding and removing checks

   If you change the monitored processes and change the corresponding Nagiosgrapher template the data file (RRD) will not be updated. You will have to delete the .rrd file (losing all the data) or modify it (e.g., by using a Perl script and RRD::Simple).

   Example script (by Marcus Schopen):

   #!/usr/bin/perl
   
   use strict;
   use warnings;
   
   use RRD::Simple;
   
   my $rrd = RRD::Simple->new();
   
   $rrd->add_source( '/path/file.rrd', 'APACHE2' => 'GAUGE' );
