sorry for lack of updates. I’m currently on holidays without access to hi speed internet (it takes me 20 minutes to write this message).

Expect news from beginning of September.

Hi, if you have a large number of machines to check, distant sites (or for any other reason), it may be interresting to use distributed architecture.
For that, we will use satelittes.

You could find further explanations on Centreon offitial wiki here:

The installation process is simpler (and faster) as you’ll only need the nagios part.

Merethis has released Centreon 2.1.8 (I’ve missed the 2.1.7 :))
The update is very simple:

cd /usr/local/src
sudo wget
sudo tar -xzf centreon-2.1.8.tar.gz
cd centreon-2.1.8
sudo ./ -u /etc/centreon

After accepting the license, simply answer yes to all the questions you’ll see.

When finished, connect to the web interface and follow the “NEXT, NEXT, NEXT” steps.
Your database will be updated twice (from 2.1.6 to 2.1.7 then from 2.1.7 to 2.1.8).

It’s finished.

Enjoy Continue reading »

This time, we will try to migrate our centreon solution from our previous Ubuntu 8.04 LTS to our new Ubuntu 10.04 LTS edition (It should work for other version too).
To do that, you should have the same centreon version on both side (for database scheme compatibility).
I use the same IP address for my both servers (it’s for a complete replacement)

Backup your Ubuntu 8.04 LTS solution

sudo service nagios stop
sudo service centstorage stop
sudo /usr/local/centreon/cron/purgeCentstorage
sudo service centcore stop
sudo service ndo2db stop

If you are planning to monitor Windows servers, it’s highly advised to install NRPE module. On windows side, I generaly use NSCLIENT++ for host check.

You’ll be able to execute remote commands on hosts.

Installation process:

cd /usr/local/src
sudo wget
sudo tar xzfv nrpe-2.12.tar.gz
cd nrpe-2.12/
sudo ./configure --with-ssl=/usr/bin/openssl --with-ssl-lib=/usr/lib
sudo make all
sudo make install-plugin

I’ve corrected the rsyslog installation process concerning the xconsole section.
In fact as we did not use X server, we did not need this part.

Here is the diff:

Edit 50-default.conf to correct the path

sudo nano /etc/rsyslog.d/50-default.conf

At the end of the file, comment the xconsole section:

#       news.err;\
#       *.=debug;*.=info;\
#       *.=notice;*.=warn       |/dev/xconsole

Restart rsyslog:

sudo service rsyslog restart
