"nan" string next to current in graph

Post by mtimbroims »

Hi all,

I keep getting this "nan" string next to my current title in the graph legend. My graphs and rrd's are generated but nothing shows up on the graph itself.

Thanks for all the help in advance.

wait until poller.php is executed at least 4 times

- wait until poller.php is executed at least 4 times
- if nothing shows up after that, go to "Settings", set the "Poller Logging Level" to DEBUG and check cacti's log file for any errors.

Please see this thread as I'm seeing this in the log file now in DEBUG mode:

"12/02/2004 11:15:04 AM - CMDPHP: Poller[0] Host[1] WARNING: Result from CMD not valid. Partial Result:"

I had poller.php in my crontab but in settings it mentions cmd.php.

Thanks again.

Please execute poller.php by hand (from the command line) and post the output.

Your settings are ok.
