# 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 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
```
