First the poller. Log into the console or from ssh as "root". Once you have logged into the server then do the following TWO command.
If you're not use to the VI console then read on otherwise skip to this section..
cd /var/www/html/poller.php vi poller.php
Navigating the code: Use the arrows to skim through the code.
Typing: Once you found your place to start typing just start typing, escape to navigate using arrows.
Exiting and Saving: press escape key if you have been typing, then :wq
Ok about a page or two into the code you will find the line that look like this..
Change it to TRUE and then save the code. You will need to run the poller manually in the web interface and then come back and follow the steps after running it manually back to FALSE. This should kick the poller to start to collect stats for you.
$force = FALSE
Couple of other things you might want to get running on the machine. Run these command as root from the terminal window.
Changing the network options
Synching the Time
Nightly updates - if you run into a lot of log problems with the server shut off updates.
ntpdate -u 0.pool.ntp.org
Changing the timezone
service yum stop chkconfig yum off
That should about do it. I love working with this software and it will certainly help you figure out where most of your problems reside.
yum install system-config-date system-config-date
