Raspberry Pi Poller Installation for Centreon 23.10 (Testing and Unstable Repository)


Before we dive into the installation process, here's a handy tip: You can easily set up a Raspberry Pi collector, even if your central server runs version 23.04.x of Centreon.


Step 1: Download the Unattended.sh Script

Begin by downloading the essential script. Open your terminal and navigate to the temporary directory:

cd /tmp
wget https://raw.githubusercontent.com/centreon/centreon/develop/centreon/unattended.sh

 

Step 2: Install Centreon

Install Centreon with a breeze using the following command. It's as simple as running this script:

bash /tmp/unattended.sh install -t poller -v 23.10 -r unstable -l DEBUG  2>&1 |tee -a /tmp/unattended-$(date +"%m-%d-%Y-%H%M%S").log

 

Step 3: Register Your Poller

Connect your poller to the central server with this quick command. Replace <API_ACCOUNT>, <IP_TARGET_NODE>, and <POLLER_NAME> with your specific details:

bash /usr/share/centreon/bin/registerServerTopology.sh -u <API_ACCOUNT> -t poller -h <IP_TARGET_NODE> -n <POLLER_NAME>

 

Step 4: Continue with Centreon's Official Documentation

Now that your poller is up and running, it's time to explore Centreon's official documentation for more in-depth guidance.

 

Step 5: Start Monitoring Resources

Follow the documentation's instructions to kickstart your resource monitoring journey. You're on your way to efficient Raspberry Pi-based monitoring with Centreon!

With these simplified steps, you'll have your Raspberry Pi poller set up and ready to monitor in no time.

Enjoy monitoring with Centreon 23.10!

Good morning @Laurent i had some issues installing centreon on my raspberry pi3. I installed debian 11 but the unattended.sh script fails with this error message:

E: Failed to fetch https://packages.centreon.com/apt-standard-23.10-unstable/pool/perl-libssh-session-arm64/libssh-session-perl_0.8-2_arm64.deb  404   [IP: 52.49.160.245 443]

I got into https://packages.centreon.com/apt-standard-23.10-unstable/pool but i could not find perl-libssh-session-arm64/libssh-session-perl_0.8-2_arm64.deb package

HI @AselDonlo7 , we are releasing Centreon 23.10.0 stable, can you retry with ‘-r stable’ option (instead or ‘-r unstable’)?

Hi @Laurent i tried it with the ‘stable’ option but this is the output that i have now

I noticed this in the apt-standard-23.10-stable/dists/bullseye/main/binary-arm64/Packages file:
 

 

Maybe this could be the problem?

Hi @AselDonlo7 did you retry to reinstall a poller on your Raspberry?

Hi @Laurent i did it and worked fine but now I have some errors when I run the script.

 

It seems that gives an error when does chown and chmod to /etc/centreon/conf.pm file because does not exist:

chmod: no se puede acceder a '/etc/centreon/conf.pm': No existe el fichero o el directorio
fallo al cambiar el modo de '/etc/centreon/conf.pm' de 0644 (rw-r--r--) a 0664 (rw-rw-r--)

Hi all, is it possible to register a Raspberry poller to a Cloud instance of Centreon ?

Thanks a lot !

Hello Mouvertus,

It is possible to register poller running on Alma8, 9 and Debian 11.

If I decrypt your pseudonym, I think we have a meet next Tuesday during which we can cover this.

Best Regards,

Nils

¿Would it be possible to fix this?

Hi Laurent
I have tried t install a poller on a Raspberry pi 4 running following Raspberry OS:

PRETTY_NAME="Raspbian GNU/Linux 11 (bullseye)"
NAME="Raspbian GNU/Linux"
VERSION_ID="11"
VERSION="11 (bullseye)"
VERSION_CODENAME=bullseye
ID=raspbian
ID_LIKE=debian

But I get the following issue when running the unattended.sh script:

root@pollerpi:/tmp# bash /tmp/unattended.sh install -t poller -v 23.10 -r stable -l DEBUG  2>&1 |tee -a /tmp/unattended-$(date +"%m-%d-%Y-%H%M%S").log
