Cacti

Yes, cmd.php triggers a bunch of stuff including the creation of rrd's if they are not there. The way I make my cron work is to create some cactiuser as a user account, become that user then do a 'crontab -e' and make the first line like: */5 * * * * /usr/bin/php /var/www/html/cacti/cmd.php > /dev/...

Some questions: 1) Have you defined polling hosts and data sources? 2) If you run cm.php (in the cacti directory) what does it report? You should see OIDs and data value (N:xxxxxx) updates to the rra's. I was just now running php cmd.php and it's gone off and done loads of stuff. Very odd. Seems to...

No, that's fine, I won't use Cacti, NaP :-/

Check your path configuration for errors - you have teo types of slash in your path too rrdtool, at the very least !
