# HP Smart Storage Arrays collector
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](https://github.com/netdata/netdata/blob/master/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](https://github.com/netdata/netdata/blob/master/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](https://github.com/netdata/netdata/blob/master/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](https://github.com/netdata/netdata/blob/master/docs/configure/start-stop-restart.md) for your system.
### Troubleshooting
To troubleshoot issues with the `hpssa` module, run the `python.d.plugin` with the debug option enabled. The
output will give you the output of the data collection job or error messages on why the collector isn't working.
First, navigate to your plugins directory, usually they are located under `/usr/libexec/netdata/plugins.d/`. If that's
not the case on your system, open `netdata.conf` and look for the setting `plugins directory`. Once you're in the
plugin's directory, switch to the `netdata` user.
```bash
cd /usr/libexec/netdata/plugins.d/
sudo su -s /bin/bash netdata
```
Now you can manually run the `hpssa` module in debug mode:
```bash
./python.d.plugin hpssa debug trace
```
