Templates​
The Monitoring Connector Centreon Poller brings a host template:
- App-Monitoring-Centreon-Poller-custom
The connector brings the following service templates (sorted by the host template they are attached to):
- App-Monitoring-Centreon-Poller-custom
Service Alias | Service Template | Service Description |
---|---|---|
Broker-Stats | App-Monitoring-Centreon-Broker-Stats-Poller-custom | Check Centreon Broker processes statistics |
proc-centengine | App-Monitoring-Centreon-Process-centengine-custom | Check centreon-engine process |

Prerequisites​
SNMP​
SNMP must be configured on each poller being monitored. You can refer to this documentation to find out how to set up a quick SNMP configuration.
SSH key exchange​
One of the checks included in the pack is performed through SSH. The central server should be able to connect to each poller being monitored.
The central server performs its checks as the centreon-engine user, and will log in to the pollers as the centreon user.
Follow these steps to exchange the SSH key:
- On the poller being monitored by the central server, set a password for the centreon user:
passwd centreon
- On the central server, create and copy the new centreon-user's SSH key on the poller:
su - centreon-engine
ssh-keygen -t ed25519 -a 100
ssh-copy-id -i ~/.ssh/id_ed25519.pub centreon@<IP_POLLER>
Installing the monitoring connector​
Pack​
- If the platform uses an online license, you can skip the package installation instruction below as it is not required to have the connector displayed within the Configuration > Monitoring Connector Manager menu. If the platform uses an offline license, install the package on the central server with the command corresponding to the operating system's package manager:
- Alma / RHEL / Oracle Linux 8
- Alma / RHEL / Oracle Linux 9
- Debian 11
- CentOS 7
dnf install centreon-pack-applications-monitoring-centreon-poller
dnf install centreon-pack-applications-monitoring-centreon-poller
apt install centreon-pack-applications-monitoring-centreon-poller
yum install centreon-pack-applications-monitoring-centreon-poller
- Whatever the license type (online or offline), install the Centreon Poller connector through the Configuration > Monitoring Connectors Manager menu.
Plugin​
Since Centreon 22.04, you can benefit from the 'Automatic plugin installation' feature. When this feature is enabled, you can skip the installation part below.
You still have to manually install the plugin on the poller(s) when:
- Automatic plugin installation is turned off
- You want to run a discovery job from a poller that doesn't monitor any resource of this kind yet
More information in the Installing the plugin section.
Use the commands below according to your operating system's package manager:
- Alma / RHEL / Oracle Linux 8
- Alma / RHEL / Oracle Linux 9
- Debian 11
- CentOS 7
dnf install centreon-plugin-Applications-Monitoring-Centreon-Poller
dnf install centreon-plugin-Applications-Monitoring-Centreon-Poller
apt install centreon-plugin-applications-monitoring-centreon-poller
yum install centreon-plugin-Applications-Monitoring-Centreon-Poller
Using the monitoring connector​
Using a host template provided by the connector​
- Log into Centreon and add a new host through Configuration > Hosts.
- Fill the Name, Alias & IP Address/DNS fields according to your ressource settings.
- Apply the App-Monitoring-Centreon-Poller-custom template to the host. A list of macros appears. Macros allow you to define how the connector will connect to the resource, and to customize the connector's behavior.
- Fill in the macros you want. Some macros are mandatory.
Macro | Description | Default value | Mandatory |
---|---|---|---|
MODULESTATSFILE | Specify the centreon-broker json stats file (required). Can be multiple | /var/lib/centreon-engine/*-module-stats.json | X |
SNMPEXTRAOPTIONS | Any extra option you may want to add to every command (a --verbose flag for example). All options are listed here. |
- Deploy the configuration. The host appears in the list of hosts, and on the Resources Status page. The command that is sent by the connector is displayed in the details panel of the host: it shows the values of the macros.
Using a service template provided by the connector​
- If you have used a host template and checked Create Services linked to the Template too, the services linked to the template have been created automatically, using the corresponding service templates. Otherwise, create manually the services you want and apply a service template to them.
- Fill in the macros you want (e.g. to change the thresholds for the alerts). Some macros are mandatory (see the table below).
- Broker-Stats
- proc-centengine
- proc-gorgoned
- proc-ntpd
- proc-sshd

- Deploy the configuration. The service appears in the list of services, and on the Resources Status page. The command that is sent by the connector is displayed in the details panel of the service: it shows the values of the macros.
How to check in the CLI that the configuration is OK and what are the main options for?​
Once the plugin is installed, log into your Centreon poller's CLI using the
centreon-engine user account (su - centreon-engine
). Test that the connector
is able to monitor a resource using a command like this one (replace the sample values by yours):
/usr/lib/centreon/plugins/centreon_centreon_poller.pl \
--plugin=apps::centreon::local::plugin \
--hostname=10.0.0.1 \
--mode=broker-stats \
--broker-stats-file='/var/lib/centreon-engine/*-module-stats.json' \
--filter-name='' \
--warning-speed-events='' \
--critical-speed-events='' \
--warning-queued-events='' \
--critical-queued-events='' \
--warning-unacknowledged-events='' \
--critical-unacknowledged-events='' \
--warning-status='' \
--critical-status='%{type} eq "output" and %{queue_file_enabled} =~ /true|yes/i' \
--verbose \
--ssh-username='centreon'
The expected command output is shown below:
OK: Broker statistics are ok | '*endpoint*#speed-events'=events/s;;;0;'*endpoint*#queued-events'=events;;;0;'*endpoint*#unacknowledged-events'=events;;;0;
Troubleshooting​
Please find the troubleshooting documentation for Centreon Plugins typical issues.
Available modes​
In most cases, a mode corresponds to a service template. The mode appears in the execution command for the connector. In the Centreon interface, you don't need to specify a mode explicitly: its use is implied when you apply a service template. However, you will need to specify the correct mode for the template if you want to test the execution command for the connector in your terminal.
All available modes can be displayed by adding the --list-mode
parameter to
the command:
/usr/lib/centreon/plugins/centreon_centreon_poller.pl \
--plugin=apps::centreon::local::plugin \
--list-mode

--output-xml | Return the output in XML format (to send to an XML API). |
--output-json | Return the output in JSON format (to send to a JSON API). |
--output-openmetrics | Return the output in OpenMetrics format (to send to a tool expecting this format). |
--output-file | Write output in file (can be combined with json, xml and openmetrics options). E.g.: --output-file=/tmp/output.txt will write the output in /tmp/output.txt. |
--disco-format | Applies only to modes beginning with 'list-'. Returns the list of available macros to configure a service discovery rule (formatted in XML). |
