HP Smart Storage Arrays monitoring with Netdata

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

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 password.

Add to sudoers:

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

To collect metrics, the module executes: sudo -n ssacli ctrl all show config detail

This module produces:

1. Controller state and temperature
2. Cache module state and temperature
3. Logical drive state
4. Physical drive state and 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, to finish enabling the hpssa collector.

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.
