# 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. ```bash netdata ALL=(root) NOPASSWD: /path/to/ssacli ``` - Reset Netdata's systemd unit [CapabilityBoundingSet](https://www.freedesktop.org/software/systemd/man/systemd.exec.html#Capabilities) (Linux distributions with systemd) 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: ```cmd 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](/docs/configure/nodes.md), which is typically at `/etc/netdata`, to edit the `python.d.conf` file. ```bash 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](/docs/configure/start-stop-restart.md) for your system. ## Configuration Edit the `python.d/hpssa.conf` configuration file using `edit-config` from the Netdata [config directory](/docs/configure/nodes.md), which is typically at `/etc/netdata`. ```bash 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`. ```yaml ssacli_path: /usr/sbin/ssacli ``` Save the file and restart the Netdata Agent with `sudo systemctl restart netdata`, or the [appropriate method](/docs/configure/start-stop-restart.md) for your system.
