Monitoring Connector Assets​

Monitored Objects​

The Monitoring Connector IBM HMC SSH collects metrics for:

  • Hardware errors
  • Led status

Collected Metrics​

No metrics.


The centreon-engine user performs a SSH connection to a remote system user. This user must have enough privileges to run lssvcevents and lsled commands.


  1. Install the Centreon Plugin on every Poller:
yum install centreon-plugin-Hardware-Servers-Ibm-Hmc-Ssh
  1. On the Centreon Web interface in Configuration > Monitoring Connector Manager, install the IBM HMC SSH Monitoring Connector


  • Add a new Host and apply the HW-Server-IBM-Hmc-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 test the Plugin and what are the main options for?​

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

/usr/lib/centreon/plugins/ \
--plugin=hardware::server::ibm::hmc::ssh::plugin \
--mode=led-status \
--hostname= \
--ssh-username=centreon \
--ssh-password='centreon-password' \
--ssh-backend=libssh \

Expected command output is shown below:

OK: System 'Server-8203-E4Z-SNE6DFXA5' physical led state : off - All virtual partition status are ok |
System 'Server-8203-E4Z-SNE6DFXA5' physical led state : off
Virtual partition 'Server-8203-E4Z-SNE6DFXA5:LPAR1' led state : off
Virtual partition 'Server-8203-E4Z-SNE6DFXA5:LPAR2' led state : off

The command above gets the led status of IBM HMC (--mode=led-status). 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= on the SSH default port 22 (--ssh-port=22).

All the options as well as all the available thresholds can be displayed by adding the --help parameter to the command:

/usr/lib/centreon/plugins/ \
--plugin=hardware::server::ibm::hmc::ssh::plugin \
--mode=led-status \


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 ssh or plink on the Centreon Poller.
