<!-- title: "MegaRAID controller monitoring with Netdata" custom_edit_url: https://github.com/netdata/netdata/edit/master/collectors/python.d.plugin/megacli/README.md sidebar_label: "MegaRAID controllers" --> # MegaRAID controller monitoring with Netdata Collects adapter, physical drives and battery stats. ## 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. Add to `sudoers`: ``` netdata ALL=(root) NOPASSWD: /path/to/megacli ``` 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** ## 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 your agent's [config directory](/docs/step-by-step/step-04.md#find-your-netdataconf-file), 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/megacli.conf ``` Battery stats disabled by default. To enable them, modify `megacli.conf`. ```yaml do_battery: yes ``` --- [](<>)
