HP Smart Storage Arrays monitoring with Netdata

Monitors controller, cache module, logical and physical drive state and temperature using ssacli tool.

Executed commands:

  • sudo -n ssacli ctrl all show config detail

Requirements:​

This module uses ssacli, which can only be executed by root. It uses sudo and assumes that it is configured such that the netdata user can execute ssacli as root without a password.

  • Add to your /etc/sudoers file:

which ssacli shows the full path to the binary.

netdata ALL=(root)       NOPASSWD: /path/to/ssacli

The default CapabilityBoundingSet doesn't allow using sudo, and is quite strict in general. Resetting is not optimal, but a next-best solution given the inability to execute ssacli using sudo.

As the root user, do the following:

mkdir /etc/systemd/system/netdata.service.d
echo -e '[Service]\nCapabilityBoundingSet=~' | tee /etc/systemd/system/netdata.service.d/unset-capability-bounding-set.conf
systemctl daemon-reload
systemctl restart netdata.service

Charts​

  • Controller status
  • Controller temperature
  • Logical drive status
  • Physical drive status
  • Physical drive temperature

Enable the collector​

The hpssa collector is disabled by default. To enable it, use edit-config from the Netdata config directory, which is typically at /etc/netdata, to edit the python.d.conf file.

cd /etc/netdata   # Replace this path with your Netdata config directory, if different
sudo ./edit-config python.d.conf

Change the value of the hpssa setting to yes. Save the file and restart the Netdata Agent with sudo systemctl restart netdata, or the appropriate method for your system.

Configuration​

Edit the python.d/hpssa.conf configuration file using edit-config from the Netdata config directory, which is typically at /etc/netdata.

cd /etc/netdata   # Replace this path with your Netdata config directory, if different
sudo ./edit-config python.d/hpssa.conf

If ssacli cannot be found in the PATH, configure it in hpssa.conf.

ssacli_path: /usr/sbin/ssacli

Save the file and restart the Netdata Agent with sudo systemctl restart netdata, or the appropriate method for your system.
