[mrtg] help with MRTG-2.16.3 & OS X 10.6.3

[jwiggins]

Hi MRTG team:

Thanks for taking a few mins to read this. So I made it past the Pod::Usage module compile/install.

My next step moving forward is to use cfgmaker, which at first I got errors (which may be my problem with indexmaker), but it generated the file. Now to use indexmaker, and I'm getting the following error message:


Use of uninitialized value $first in hash element at /Users/xyzcorp/Downloads/mrtg-2.16.3/bin/indexmaker line 353.

this is the line # 353  --- my $host = $$rcfg{host}{$first};

I've looked at 3 or 4 sample snmpd.conf files and made sure mine followed the best practices I saw


I can't do an SNMPWALK though
snmpwalk -v 1 -c public localhost systemSNMPv2-MIB::sysContact.0 = STRING: Administrator xyz at salon.com

End of MIB

or...

WebServer root# snmpwalk -v 1 -c public localhost IP-MIB::ipAdEntIfIndex
End of MIB


I am just nearing a deadline and am struggling with this setup. Thank you very much for looking at my problem
