-Collects logical and physical devices metrics.
+Collects logical and physical devices metrics using `arcconf` command-line utility.
+
+Executed commands:
+
+- `sudo -n arcconf GETCONFIG 1 LD`
+- `sudo -n arcconf GETCONFIG 1 PD`
 
 ## Requirements
 
-The module uses `arcconf`, which can only be executed by root.  It uses
-`sudo` and assumes that it is configured such that the `netdata` user can
-execute `arcconf` as root without password.
+The module uses `arcconf`, which can only be executed by `root`. It uses
+`sudo` and assumes that it is configured such that the `netdata` user can execute `arcconf` as root without a password.
 
-Add to `sudoers`:
+-  Add to your `/etc/sudoers` file:
 
-```
+`which arcconf` shows the full path to the binary.
+
+```bash
 netdata ALL=(root)       NOPASSWD: /path/to/arcconf
 ```
 
-To grab stats it executes:
+- Reset Netdata's systemd
+  unit [CapabilityBoundingSet](https://www.freedesktop.org/software/systemd/man/systemd.exec.html#Capabilities) (Linux
+  distributions with systemd)
 
--   `sudo -n arcconf GETCONFIG 1 LD`
--   `sudo -n arcconf GETCONFIG 1 PD`
+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 `arcconf` using `sudo`.
 
-It produces:
 
-1.  **Logical Device Status**
+As the `root` user, do the following:
 
-2.  **Physical Device State**
+```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
+```
 
-3.  **Physical Device S.M.A.R.T warnings**
+## Charts
 
-4.  **Physical Device Temperature**
+- Logical Device Status
+- Physical Device State
+- Physical Device S.M.A.R.T warnings
+- Physical Device Temperature
