Monitoring Connector Assets​

Monitored Objects​

The Monitoring Connector includes monitoring the AIX system commands using SSH, such as:

  • Command return
  • Errpt messages
  • Inodes
  • Group volumes
  • Processes
  • Storage

Collected Metrics​

Metric nameDescriptionUnit
command.exit.code.countNumber of exit code returncount


A user is required to query the OS AIX by SSH. There is no need for root or sudo privileges. There are two possible ways to perform SSH check, either by exchanging the SSH key from centreon-engine to the target server, or by setting your unique user and password directly in the host macros.

Add and generate a password for your user on the Target sever:

adduser ro_ssh_centreon
passwd ro_ssh_centreon

Switch to centreon-engine's bash environment on your Central server and Poller :

su - centreon-engine

Then, copy this key on to the Target server with the following commands:

ssh-keygen -t ed25519 -a 100
ssh-copy-id -i .ssh/ ro_ssh_centreon@<IP_TARGET_SERVER>


  1. Install the Centreon Plugin on every Poller:
yum install centreon-plugin-Operatingsystems-Aix-Local
  1. On the Centreon Web interface in Configuration > Monitoring Connector Manager, install the AIX SSH Monitoring Connector


  • Add a new Host and apply the OS-AIX-SSH-custom Host Template

3 SSH backends are available to connect to the remote server: sshcli, plink and libssh which are detailed below.

XSSHBACKENDName of the backend: sshcli
XSSHUSERNAMEBy default, it uses the user running process centengine on your Poller
SSHPASSWORDCannot be used with backend. Only ssh key authentication
SSHPORTBy default: 22
SSHEXTRAOPTIONSCustomize it with your own if needed. E.g.: --ssh-priv-key=/user/.ssh/id_rsa

Warning With that backend, you have to validate the target server fingerprint manually (with the SSHUSERNAME used).

How to check in the CLI that the configuration is OK and what are the main options for ?​

Once the Plugin installed, log into your Poller using the centreon-engine user account and test by running the following command :

/usr/lib/centreon/plugins/ \
--plugin=os::aix::local::plugin \
--mode=lvsync \
--hostname= \
--ssh-username=centreon \
--ssh-password='centreon-password' \
--ssh-backend=sshcli \
--filter-type='SVG' \
--critical-status='%{state} =~ /stale/i'\

The above command controls the state of volumes groups mirroring (--mode=lvsync). It uses a SSH username centreon (--ssh-username=centreon), a SSH password centreon-password (--ssh-password='centreon-password'), uses a SSH backend libssh (--ssh-backend='libssh') and it connects to the host (--hostname=

All the options that can be used with this plugin can be found over the --help options:

/usr/lib/centreon/plugins/ \
--plugin=os::aix::local::plugin \
--mode=lvsync \


I have that error message: UNKNOWN: Command error: Host key verification failed.. What does it mean ?​

It means you haven't manually validated the target server fingerprint with libssh or plink on the Centreon Poller.
