I just went through the same issue.  Check your linux security settings.
Do a `getenforce` command and see if it's says "enforcing" which means
SElinux is enabled.  If it does, put selinux=0 at the end of the kernel
line in your grub.conf.  Then reboot.

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!

I am on Solaris 9, and still digging

Most of those who have problems on Solaris is because the shared
libraries used by Hobbit are in /usr/local/lib, which is not searched
by default by the dynamic linker.

Try adding

   LD_LIBRARY_PATH=/usr/local/lib
   export LD_LIBRARY_PATH

at the top of your hobbitcgi.cfg file, or use the "crle" utility to
include /usr/local/lib in your system's default library path.

I have written some checks for both esx 25x and esx3.

These should probably be re-written at some stage, just haven't taken the
time to yet, but I hope you get some ideas.

For ESX 3.0.1 and up you can take the OO approach with VMPerl  (See
example one) [it's very slow]. I say use 3.0.1 because although the sdk
manual says these methods are supported in esx 3.0.0 there seem to be some
problems with VmPerl that are fixed in 3.0.1.

Or you can do most of this stuff by parsing the /proc nodes (see example 2
and 3 below)

EX 1.
use VMware::VmPerl;

        my $cfg_path = $get_vmx_info[2];
        $cfg_path =~ s/cfgFile.//g;
        $cfg_path =~ s/\"//g;
        #print "$cfg_path\n"; }

        my $connect_params = VMware::VmPerl::ConnectParams::new;
        my $vm = VMware::VmPerl::VM::new();
        my $i;
        if (!$vm->connect($connect_params, $cfg_path)) {
        my ($error_number, $error_string) = $vm->get_last_error();
        undef $vm;
        die "Could not connect to vm: Error $error_number:
$error_string\n";
        }

        my $name1 = $vm->get_config('displayName');

        my $mem_swap_in = $vm->get_resource('mem.swapin');
        my $mem_shared = $vm->get_resource('mem.shared');


        print

I'll get round to cleaning these up and making them available at some

Hope you get some ideas from these.
