  1. Hi,

    Great job ! But why nobody update official Wiki of centreon ? If you want to help us, centreon wiki is completely open !

    There are many tuto who speak about centreon… and nobody help centreon team 🙁


  2. Awesome job, it’s working.-

  3. Hi, I have installed nagios and centreon ok, but am getting a blank main.php after login. Any ideas how to figure out what is wrong?

  4. Hi, i have the same problem, I am getting a blank main.php after login. What can i do?

  5. first of all, if you are using debian, do not use manually compiled things but apt-get install nagios3.
    please check my website as I will provide centreon2 w/nagios3 in Debian lenny tutorial soon there.

  6. If you have a blank main.php – maybe you need the gettext module for php, but always look into your apache error log

  7. #Here’s the solution to blank page problem.
    ls /usr/local/apache2/conf
    #you will find a file named centreon.conf here
    #copy it to /etc/apache2/conf.d
    sudo cp /usr/local/apache2/conf/centreon.conf /etc/apache2/conf.d
    #restart nagios, centcore and apache2
    sudo /etc/init.d/nagios restart
    sudo /etc/init.d/centreon restart
    sudo /etc/init.d/apache2 restart
    # I hope this will solve your problems 🙂

  8. Hi, I’m getting a blank main.php when I try to access http://my_server/nagios/main.php. I tried the above fix, but it didn’t work. nagios/log/error-login-2010-08-16.log shows that I’m logging in but nothing is showing up. Does anybody have any ideas?
