# 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](/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 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](/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 ``` []()
