I switched over from nagiosgraph to PNP4Nagios just to use this plugin, definitely worthwhile if you're monitoring a lot of VMs. It's a bit of a pain to have to add guests manually to each host, and there is no support for monitoring guests automatically during migration, however I don't know if there's a better way and appending a hostname to one line when a guest is added is much better than having to add multiple lines of config. Having the graphs auto-populate the way they do is a huge timesaver.

Nice easy to use plugin. I did make a couple of changes on the plugin on my environment:

Added an extra function to change Bytes into MBytes:
sub normalize {
my $megabits = $_[0] / 1048576;
return $megabits;

Then at the end of the script added the following to line 178:

if($option eq "gueststorage") {
#Convert Display to MB/s
my @originalSpeed = $columns[0] =~ m/= (d+.d+)/;
my $speed = sprintf("%.2f", normalize($originalSpeed[0]));
$columns[0] =~ s/$originalSpeed[0] b/s/$speed MB/s/;

#Convert Perf Data to MB/s
my @originalSpeed = $columns[1] =~ m/=(d+.d+)/;
my $speed = sprintf("%.2f", normalize($originalSpeed[0]));
$columns[1] =~ s/$originalSpeed[0]b/s/${speed}MB/s/;


It just puts the Bytes/s into MBytes/s when using "gueststorage" and rounds to 2 decimal places just for easier readability.
