# MegaRAID controller monitoring with Netdata
-Collects adapter, physical drives and battery stats.
+Collects adapter, physical drives and battery stats using `megacli` command-line tool.
+
+Executed commands:
+
+- `sudo -n megacli -LDPDInfo -aAll`
+- `sudo -n megacli -AdpBbuCmd -a0`
## Requirements
-Uses the `megacli` program, which can only be executed by root. It uses
-`sudo` and assumes that it is configured such that the `netdata` user can
-execute `megacli` as root without password.
+The module uses `megacli`, which can only be executed by `root`. It uses
+`sudo` and assumes that it is configured such that the `netdata` user can execute `megacli` as root without a password.
-Add to `sudoers`:
+- Add to your `/etc/sudoers` file:
-```
+`which megacli` shows the full path to the binary.
+
+```bash
netdata ALL=(root) NOPASSWD: /path/to/megacli
```
+- Reset Netdata's systemd
+ unit [CapabilityBoundingSet](https://www.freedesktop.org/software/systemd/man/systemd.exec.html#Capabilities) (Linux
+ distributions with systemd)
-To grab stats it executes:
+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 `megacli` using `sudo`.
-- `sudo -n megacli -LDPDInfo -aAll`
-- `sudo -n megacli -AdpBbuCmd -a0`
-It produces:
+As the `root` user, do the following:
-1. **Adapter 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
+```
-2. **Physical Drives Media Errors**
+## Charts
-3. **Physical Drives Predictive Failures**
+- Adapter State
+- Physical Drives Media Errors
+- Physical Drives Predictive Failures
+- Battery Relative State of Charge
+- Battery Cycle Count
-4. **Battery Relative State of Charge**
+## Enable the collector
-5. **Battery Cycle Count**
+The `megacli` 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 `megacli` setting to `yes`. Save the file and restart the Netdata Agent
+with `sudo systemctl restart netdata`, or the appropriate method for your system.
## Configuration
-**megacli** is disabled by default. Should be explicitly enabled in `python.d.conf`.
-
-```yaml
-megacli: yes
-```
-
-Edit the `python.d/megacli.conf` configuration file using `edit-config` from the Netdata [config
-directory](/docs/configure/nodes.md), which is typically at `/etc/netdata`.
