I decided to use a "standard" Hobbit client running on the service console, then add my own customizations:

- use vdf for disk space monitoring instead of df (picks up VMDK volumes)

- use esxtop to get CPU usage for entire ESX box

Here is a snippet I wrote for parsing ESXTOP output:

my $esxtop = "sudo /usr/bin/esxtop -b -d $interval";
open(CMD,"$esxtop |") || die "error - could not open $esxtop   $!\n";
my $count = 0;
while( <CMD> ) {
        chomp;
        s/\"//g;
        my (@row) = split/\,/;
        $count++;
        if ( $count <= 2 ) { next; }    # skip 1st few results, just titles and 100% values
        my $util = int($row[9]);        # round to INT, because RRD does not like floating-point
        &SendHobbit($util);
        if ( $verbose ) { print "util = $util\n"; }
}

I hope this helps, please don't flame my crappy code...  Enjoy!
