    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?

    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.

    Other logs:

    audit.log

    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?

    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

    output after changing permissions:

    cacti: no output
