Prerequisites​

The centreon-engine user performs a SSH connection to a remote system user. This user must have enough privileges to run nvidia-smi command.

Setup​

  1. Install the Centreon Plugin on every Poller:
yum install centreon-plugin-Hardware-Devices-Nvidia-Gpu-Smi-Ssh
  1. On the Centreon Web interface in Configuration > Monitoring Connectors Manager, install the NVIDIA GPU SMI SSH Pack

Host configuration​

  • Add a new Host and apply the HW-Device-Nvidia-Gpu-Smi-SSH-custom Host Template

Once the template applied, some Macros have to be configured. 3 SSH backends are available to connect to the remote server: sshcli, plink and libssh which are detailed below.

MandatoryNameDescription
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 Poller using the centreon-engine user account and test by running the following command :

/usr/lib/centreon/plugins/centreon_nvidia_gpu_smi_ssh.pl \
    --plugin=hardware::devices::nvidia::gpu::smi::plugin \
    --mode=stats \
    --hostname=10.30.2.81 \
    --ssh-username=centreon \
    --ssh-password='centreon-password' \
    --ssh-backend=libssh \
    --verbose

Expected command output is shown below:

The command above gets GPU statistics (--mode=stats).

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 10.30.2.81 (--hostname=10.30.2.81) 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/centreon_nvidia_gpu_smi_ssh.pl \
    --plugin=hardware::devices::nvidia::gpu::smi::plugin \
    --mode=stats \
    --help
