# megacli

Module collects adapter, physical drives and battery stats.

**Requirements:**

-   `megacli` program
-   `sudo` program
-   `netdata` user needs to be able to be able to sudo the `megacli` program without password

To grab stats it executes:

-   `sudo -n megacli -LDPDInfo -aAll`
-   `sudo -n megacli -AdpBbuCmd -a0`

It produces:

1.  **Adapter State**

2.  **Physical Drives Media Errors**

3.  **Physical Drives Predictive Failures**

4.  **Battery Relative State of Charge**

5.  **Battery Cycle Count**

## prerequisite

This 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 password.

Add to `sudoers`:

```
netdata ALL=(root)       NOPASSWD: /path/to/megacli
```

### configuration

**megacli** is disabled by default. Should be explicitly enabled in `python.d.conf`.

```yaml
megacli: yes
```

Battery stats disabled by default. To enable them modify `megacli.conf`.

```yaml
do_battery: yes
```
