+<img src="https://netdata.cloud/img/hard-drive.svg" width="150"/>
+
+
+Plugin: python.d.plugin
+Module: megacli
+

+
+## Overview
+
+Examine MegaCLI metrics with Netdata for insights into RAID controller performance. Improve your RAID controller efficiency with real-time MegaCLI metrics.
+
+Collects adapter, physical drives and battery stats using megacli command-line tool
+
+Executed commands:
+
+  -  `sudo -n megacli -LDPDInfo -aAll`
+  -  `sudo -n megacli -AdpBbuCmd -a0`
+
+
+This collector is supported on all platforms.
+
+This collector only supports collecting metrics from a single instance of this integration.
+
+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.
+
+### Default Behavior
+
+#### Auto-Detection
+
+After all the permissions are satisfied, netdata should be to execute commands via the megacli command line utility
+
+#### Limits
+
+The default configuration for this integration does not impose any limits on data collection.
+
+#### Performance Impact
+
+The default configuration for this integration is not expected to impose a significant performance impact on the system.
+
+
+## Metrics
+
+Metrics grouped by *scope*.
+
+The scope defines the instance that the metric belongs to. An instance is uniquely identified by a set of labels.
+
+
+
+### Per MegaCLI instance
+
+These metrics refer to the entire monitored application.
+
+This scope has no labels.
+
+Metrics:
+
+| Metric | Dimensions | Unit |
+|:------|:----------|:----|
+| megacli.adapter_degraded | a dimension per adapter | is degraded |
+| megacli.pd_media_error | a dimension per physical drive | errors/s |
+| megacli.pd_predictive_failure | a dimension per physical drive | failures/s |
+
+### Per battery
+
+Metrics related to Battery Backup Units, each BBU provides its own set of the following metrics.
+
+This scope has no labels.
+
+Metrics:
+
+| Metric | Dimensions | Unit |
+|:------|:----------|:----|
+| megacli.bbu_relative_charge | adapter {battery id} | percentage |
+| megacli.bbu_cycle_count | adapter {battery id} | cycle count |
+
+
+
+## Alerts
+
+
+The following alerts are available:
+
+| Alert name  | On metric | Description |
+|:------------|:----------|:------------|
+| [ megacli_adapter_state ](https://github.com/netdata/netdata/blob/master/src/health/health.d/megacli.conf) | megacli.adapter_degraded | adapter is in the degraded state (0: false, 1: true) |
+| [ megacli_pd_media_errors ](https://github.com/netdata/netdata/blob/master/src/health/health.d/megacli.conf) | megacli.pd_media_error | number of physical drive media errors |
+| [ megacli_pd_predictive_failures ](https://github.com/netdata/netdata/blob/master/src/health/health.d/megacli.conf) | megacli.pd_predictive_failure | number of physical drive predictive failures |
+| [ megacli_bbu_relative_charge ](https://github.com/netdata/netdata/blob/master/src/health/health.d/megacli.conf) | megacli.bbu_relative_charge | average battery backup unit (BBU) relative state of charge over the last 10 seconds |
+| [ megacli_bbu_cycle_count ](https://github.com/netdata/netdata/blob/master/src/health/health.d/megacli.conf) | megacli.bbu_cycle_count | average battery backup unit (BBU) charge cycles count over the last 10 seconds |
+
+
+## Setup
+
+### Prerequisites
+
+#### Grant permissions for netdata, to run megacli as sudoer
+
+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 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 (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 arcconf using sudo.
+
+As root user, do the following:
+
+```bash
+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
+```
+
+
+
+### Configuration
+
+#### File
+
+The configuration file name for this integration is `python.d/megacli.conf`.
+
+
+You can edit the configuration file using the `edit-config` script from the
+Netdata [config directory](https://github.com/netdata/netdata/blob/master/docs/netdata-agent/configuration.md#the-netdata-config-directory).
+
+```bash
+cd /etc/netdata 2>/dev/null || cd /opt/netdata/etc/netdata
+sudo ./edit-config python.d/megacli.conf
+```
+#### Options
+
+There are 2 sections:
+
+* Global variables
+* One or more JOBS that can define multiple different instances to monitor.
+
+The following options can be defined globally: priority, penalty, autodetection_retry, update_every, but can also be defined per JOB to override the global values.
+
+Additionally, the following collapsed table contains all the options that can be configured inside a JOB definition.
+
+Every configuration JOB starts with a `job_name` value which will appear in the dashboard, unless a `name` parameter is specified.
+
+
+<details><summary>Config options</summary>
+
+| Name | Description | Default | Required |
+|:----|:-----------|:-------|:--------:|
+| update_every | Sets the default data collection frequency. | 5 | no |
+| priority | Controls the order of charts at the netdata dashboard. | 60000 | no |
+| autodetection_retry | Sets the job re-check interval in seconds. | 0 | no |
+| penalty | Indicates whether to apply penalty to update_every in case of failures. | yes | no |
+| do_battery | default is no. Battery stats (adds additional call to megacli `megacli -AdpBbuCmd -a0`). | no | no |
+
+</details>
+
+#### Examples
+
+##### Basic
+
+A basic example configuration per job
+
+```yaml
+job_name:
+    name: myname
+    update_every: 1
+    priority: 60000
+    penalty: yes
+    autodetection_retry: 0
+
+```
+
+
+## Troubleshooting
+
+### Debug Mode
+
+To troubleshoot issues with the `megacli` collector, run the `python.d.plugin` with the debug option enabled. The output
+should give you clues as to why the collector isn't working.
+
+- Navigate to the `plugins.d` directory, usually at `/usr/libexec/netdata/plugins.d/`. If that's not the case on
+  your system, open `netdata.conf` and look for the `plugins` setting under `[directories]`.
+
+  ```bash
+  cd /usr/libexec/netdata/plugins.d/
+  ```
+
+- Switch to the `netdata` user.
+
+  ```bash
+  sudo -u netdata -s
+  ```
+
+- Run the `python.d.plugin` to debug the collector:
+
+  ```bash
+  ./python.d.plugin megacli debug trace
+  ```

+            Additionally, the following collapsed table contains all the options that can be configured inside a JOB definition.
+            
+            Every configuration JOB starts with a `job_name` value which will appear in the dashboard, unless a `name` parameter is specified.
