cacti help - no data on graphs

Ok, so I set it all up, but there were no graphs, so I read the docs and
tested by executing poller.php manual, at which point the rra data
appeared and I had graphs, but no data on those graphs. I reset the
permissions on the .rrd files to cacti/cacti 664 but still nothing. I
checked cron and it had a cacti file in cron.d with the line

#*/5 * * * *         cacti     /usr/bin/php /usr/share/cacti/poller.php

> /dev/null 2>&1

And if I execute /usr/bin/php /usr/share/cacti/poller.php directly it
does work to refresh the data in /usr/share/cacti/rra/ but I am not sure
what > dev/null 2>&1 is doing. If I execute poller with that on the end
it does not seem to do anything. And still no graph data.



I am using cacti 0.8.6i with php 5.1.6 and snmp V1 to get data and if I
run 'snmpget -v 1 -c public 192.168.2.50 1.3.6.1.2.1.2.2.1.10.51' from
the command line I get counter data.



Any thoughts?
