You can get remote data from a server by simply starting a script
that gives 4 lines of MRTG data on standard out from inetd. Ie.

mrtg stream tcp nowait nobody /local/sbin/tcpd /local/mrtg/bin/load

and a line like this in /etc/services:

mrtg 1020/tcp

and a script like this in /local/mrtg/bin/load:

---8<---
#!/local/bin/perl -w

use strict;

my $uptime_command = '/local/gnu/bin/uptime';
my $r = `$uptime_command` or die "Can't execute $uptime_command: $!\n";

my ($l5, $l15) = ($r =~ /load average:\s+\d+\.\d+,\s+(\d+\.\d+),\s+(\d+\.\d+)/);
print "$l5\n$l15\n0\n0\n";
---8<---

This would solve your problems, if I understood you right.

BTW, your message is difficult to read. Please limit your line length
to around 72 characters.
