[mrtg] Re: rateup problems

[Wright, Christopher W, CONTRACTOR Fort Carson]

Tim,

   Thanks for your help.  I found out that ld.so.1 was pointing to the
/usr/lib directory, while the files needed were installed in /usr/local/lib.
Everything seems to be working now.

If you can run mrtg by hand and everything works, then perhaps cron is not
getting a correct LD_LIBRARY_PATH statement, or if it's from the perl,
then you'd have an @INC error.  Have you tried running it by hand from 
/ for from /tmp, so that you're not in the directory tree?
ldconfig might need to be run, after verifying that libpng2 is in a
directory that is listed in /etc/ld.so.conf.

Or you can try building your mrtg into a perl script that uses chdir, and
then put that in cron to be run.  Your mrtg might work that way if you
can run it by hand.

Like:

########################
#!/usr/local/bin/perl -w
# 
# a script to run mrtg from the mrtg directory.
# from "Programming Perl."

use Cwd 'chdir';

chdir "/mrtg/mrtg-2.8.9/run/";

@args = ("/mrtg/mrtg-2.8.9/run/mrtg", "/mrtg/mrtg-2.8.9/run/mrtg.cfg")
system (@args) == 0 
	or die "system @args failed: $?"

# End
########################

With a little modification, this can also be re-written into a script that
will run mrtg against a whole slew of mrtg config files, first sorting
them, then running a constant 4 mrtg processes, until all the configs
have been run.  At least, that's how I did it.

YMMV,

-Tim
