cacti help - no data on graphs

[Bryan O'Neal]

Well, I uncommented cacti and replaced the contents of /usr/share/cacti
with a fresh install, I deleted and re-imported the cacti db, I
uncommented the line in cron, and I set all the permissions.  The system
generated the .rrd files for me and I get a graph preview, but still no
data?

My cacti log says
03/19/2007 07:00:04 PM - SYSTEM STATS: Time:3.0026 Method:cmd.php
Processes:1 Threads:N/A Hosts:3 HostsPerProcess:3 DataSources:233
RRDsProcessed:119

This "modified" datestamp on the file is for 6:00:04 PM MST so why is
the log entry for 7:00:04 PM?

I'm not familiar with cacti, but the # at the beginning of the cron
line will cause cron to not run the command as it looks at the line as
a comment. If it's just a problem of cron not running the command that
should fix it.

The "> /dev/null 2>&1" is sending all output from the php script to
the bit-bucket. If the script is creating files and writing to them
then this is perfectly fine.
