[hobbit] Re: Monitoring and ESX host

[Jones, Jason (Altrincham)]

When I did this I compiled the hobbit client on the esx box then edited
hobbitclient-linux.sh ($BBCLIENTHOME/bin) and added the line:

	TOP=esxtop

Just above the line:

	"# $TOP must be set, the install utility should do that for us
if it exists."

I am currently looking into a way of getting some output on what virtual
machines are actually running on the esx server and what kind of cpu
levels etc. they are at but that's on hold atm.

Thanks,
Jason.

Here is a snippet of the code I run on ESX3:

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);
}

This is a PERL script, called by the "standard" Hobbit client running
inside the service console. The only ESX-specific parameter I am
watching is overall CPU utilization. The subroutine SendHobbit "prints"
the data to tcp/1984 with the following line:

print SOCK "status $MACHINE.pcpu $COLOR $datenow\npcpuBusy : $util\n";

I was able to compile the Hobbit client on a RedHat box, then ZIP the
client and manually install on ESX. 

Good luck!
