I got the same hassle, too. The images just don't show up. If I open one of the 'images' in a seperate window, I only see a '0'. I've attached a screenshot, it's made on a German Windows edition, hope you can use it nevertheless

. I also tried to increase the log level, but there are no messages in the error.log. The error.log is writable for the webserver (Apache).

My cacti version is the one shipped w/ Debian sid, version 0.8.6c.
My rrdtool package is from Debian too, version 1.0.49.

Hope you can help me out

I forgot to enable the notify on reply function.

Now I changed to file of cacti in my /etc/cron.d directory and now I get a mail every 5 minutes with a rather fatal error:

Fatal error: Call to undefined function: mysql_connect() in /usr/share/cacti/site/lib/adodb/drivers/adodb-mysql.inc.php on line 339

But why is only the poller experiencing these problems? The cacti web interface seems to work. You can change settings etc.

I've fixed the problem.

The base line of the problem is that the command line interface PHP has a different config file than the PHP as used by Apache. If a php script runs as a cron job, the config file for the command line interface applies.

On my Debian Sid I had to change the file /etc/php4/cli/php.ini and uncomment the line
"; extension=mysql.so"

I added another line just down below:
extension=snmp.so

I just browsed the forum a litte bit; this seems prob looks like being a FAQ. Maybe you should add it to the FAQ.

Just some random thoughts
