The only data sources that I have been able to make work are the 'SNMP Network Data" types. This is the wizard like data input source that lists all the network adapters of a given device that you point it to. I am able chart this type of data source no problem.
However, when I try to use the "Get SNMP Data" Data input source I am able to retrieve data, but it doesn't want to graph it. I have tested the hostname, community string and OID from the commandline without any problem, so I know these are good. I thought maybe the problem might be the internal php SNMP, so I created my own perl script to do the same thing. But this solution didn't work either, in fact it pointed out the fact that I have the same issue with perl scripts as well. It appears that from within cacti the perl scripts don't want to work, however when run from the command line they do work.
Here are the details of my config: win2k sp2, cacti .67, Active Perl 5.6.1.631, php 4.1.2, and mysql 3.23.49.
Here is some info from within cacti showing the problem:
Data input config:
perl c:\inetpub\wwwroot\cacti/scripts/new_snmpget.pl cgusns20 public .1.3.6.1.4.1.232.11.2.4.1.1.3.0
c:\rrdtool\rrdtool.exe update c:\inetpub\wwwroot\cacti/rra/cgusns20_disk_test.rrd --template 20_disk_test N:8630
Note, that the value of 8630 is the proper value for this OID, this is the total size of the C: drive in this particular system.

$ret = `snmpget -O neEXbqfsStv $ARGV[0] $ARGV[1] $ARGV[2]`;
chomp $ret;
$ret =~ s/$ARGV[2]//;
print $ret;
Here is some output from the rrd.log. I think this is telling me that It pulled the data ok.
'04/25/2002 11:43 PM - CMD: c:\rrdtool\rrdtool.exe update c:\inetpub\wwwroot\cacti/rra/cgusns20_disk_test.rrd --template 20_disk_test N:8630'
'04/25/2002 11:48 PM - CMD: c:\rrdtool\rrdtool.exe update c:\inetpub\wwwroot\cacti/rra/cgusns20_disk_test.rrd --template 20_disk_test N:8630'
I have even run this rrdtool update command from the command prompt and not received an error.
Any ideas as to what I am doing wrong? Thanks for you help.
