cacti problem - graphs have huge gaps
 
Hi all,

I have cacti on our server (CentOS, ISP Config) but graphics have huge gaps. Do you have any idea why this is happening?

Thanks
Nuno

Any errors in your logs? Was your server running all the time, or was it down sometimes?

Chip 23rd December 2007 19:17

server is running all the time, as for the logs, I'm not quite sure which log to look at :S

Check all the log files in the /var/log directory.

Hi,

There was a table in mysql from cacti that was blocked, fixed now, but I still have the same problem.

I can't find errors when looking at /var/log/cron for this period of time:

Code:

but the graph shows gaps:

I am not able to find any other kind of errors that could be related to this.

You can try to run this command:
Code:

php /var/www/cacti/poller.php
as root and as the cacti user. Do you get any output?

Chip 6th February 2008 21:44

Hi,

no output as root, the following as cacti user:

after changing permissions no errors on both, I'll wait to see the results and report here again
