Configuring Gorgone in rebound mode

This procedure describes how to configure Gorgone between a remote poller and a central server, via a rebound server.

Note: In our case, we have the configuration described below (you must adapt the procedure to your configuration).

Central server:

  • address: 10.30.2.203

Rebound server:

  • id: 1024 (This id is an arbitrary number and must be unique).
  • address: 10.30.2.67
  • rsa public key thumbprint: NmnPME43IoWpkQoam6CLnrI5hjmdq6Kq8QMUCCg-F4g

Remote Poller:

  • id: 6 (configured in Centreon interface as zmq. You can get this id from the Centreon interface)
  • address: 10.30.2.179
  • rsa public key thumbprint: nJSH9nZN2ugQeksHif7Jtv19RQA58yjxfX-Cpnhx09s

On the remote poller side​

Installation requirements​

Ensure the remote poller and Gorgone are already installed.

Configuration​

Configure the file /etc/centreon-gorgone/config.d/40-gorgoned.yaml as follows:

name:  distant-server
description: Configuration for distant server
gorgone:
  gorgonecore:
    id: 6
    privkey: "/var/lib/centreon-gorgone/.keys/rsakey.priv.pem"
    pubkey: "/var/lib/centreon-gorgone/.keys/rsakey.pub.pem"

  modules:
    - name: action
      package: gorgone::modules::core::action::hooks
      enable: true

    - name: engine
      package: gorgone::modules::centreon::engine::hooks
      enable: true
      command_file: "/var/lib/centreon-engine/rw/centengine.cmd"

    - name: pull
      package: "gorgone::modules::core::pull::hooks"
      enable: true
      target_type: tcp
      target_path: 10.30.2.67:5556
      ping: 1

On the rebound server side​

Installation requirements​

Ensure you have installed a server with a supported OS.

Then install the Gorgone daemon using the following commands:

dnf install -y dnf-plugins-core
dnf config-manager --add-repo https://packages.centreon.com/rpm-standard/24.10/el8/centreon-24.10.repo
dnf clean all --enablerepo=*
dnf update
dnf install centreon-gorgone

Configuration​

Configure the file /etc/centreon-gorgone/config.d/40-gorgoned.yaml as follows:

name:  rebound-server
description: Configuration for rebound-server
gorgone:
  gorgonecore:
    id: 1024
    privkey: "/var/lib/centreon-gorgone/.keys/rsakey.priv.pem"
    pubkey: "/var/lib/centreon-gorgone/.keys/rsakey.pub.pem"
    external_com_type: tcp
    external_com_path: "*:5556"
    authorized_clients:
        - key: nJSH9nZN2ugQeksHif7Jtv19RQA58yjxfX-Cpnhx09s

  modules:
    - name: proxy
      package: "gorgone::modules::core::proxy::hooks"
      enable: true

    - name: pull
      package: "gorgone::modules::core::pull::hooks"
      enable: true
      target_type: tcp
      target_path: 10.30.2.203:5556
      ping: 1

On the central server side​

Installation requirements​

Ensure the Central server and Gorgone are already installed.

Configuration​

Configure the file /etc/centreon-gorgone/config.d/40-gorgoned.yaml as follows:

...
gorgone:
  gorgonecore:
    ...
    external_com_type: tcp
    external_com_path: "*:5556"
    authorized_clients:
      - key: NmnPME43IoWpkQoam6CLnrI5hjmdq6Kq8QMUCCg-F4g
    ...
  modules:
    ...
    - name: register
      package: "gorgone::modules::core::register::hooks"
      enable: true
      config_file: /etc/centreon-gorgone/nodes-register-override.yml
    ...

We created the file /etc/centreon-gorgone/nodes-register-override.yml:

nodes:
  - id: 1024
    type: pull
    prevail: 1
    nodes:
      - id: 6
        pathscore: 1
