# 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
```
