 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 password.
+`sudo` and assumes that it is configured such that the `netdata` user can execute `ssacli` as root without a password.
 
-Add to `sudoers`:
+- Add to your `/etc/sudoers` file:
 
-```
+`which ssacli` shows the full path to the binary.
+
+```bash
 netdata ALL=(root)       NOPASSWD: /path/to/ssacli
 ```
 
-To collect metrics, the module executes: `sudo -n ssacli ctrl all show config detail`
+- 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
+```

 ## 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

 ```
 
-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.
