Graphs are there but they're empty

[ckissi]

Hello,

When I installed cacti I noticed that graphs aren't renerated. Then I ran: php poller.php and it generated them. But all of them are empty. This is what I got on screen:
# /usr/bin/php /usr/share/cacti/poller.php

And this is in my cacti.log:

Also when I run the cron job: "cacti /usr/bin/php /usr/share/cacti/poller.php > /dev/null 2>&1" there is nothing in cacti.log for this run.

I did run in DEBUG mode and got this:

Seems that it collected data I just cannot see anything in graphs, there are NAN values at the bottom of graph

I have the same issue, but this occured after I did a YUM update on my Linux server. Any ideas would be helpful!

Thanks

I actually sorted 99% of my issue out. I moved the rra directory aside, created a new one and made sure the permissions were reset. That was all it took for some reason.

The other 1% is the host not returning any data, but that is easier to sort out.

Thanks for the tutorial though. I am sure it will come in very handy further down the road.
