# StoreCLI RAID


<img src="https://netdata.cloud/img/hard-drive.svg" width="150"/>


Plugin: go.d.plugin
Module: storcli

## Overview

Monitors the health of StoreCLI Hardware RAID by tracking the status of RAID adapters, physical drives, and backup batteries in your storage system.
It relies on the [`storcli`](https://docs.broadcom.com/doc/12352476) CLI tool but avoids directly executing the binary.
Instead, it utilizes `ndsudo`, a Netdata helper specifically designed to run privileged commands securely within the Netdata environment.
This approach eliminates the need to use `sudo`, improving security and potentially simplifying permission management.

Executed commands:
-  `storcli /cALL show all J nolog`
-  `storcli /cALL/eALL/sALL show all J nolog`




This collector is supported on all platforms.

This collector only supports collecting metrics from a single instance of this integration.


### Default Behavior

#### Auto-Detection

This integration doesn't support auto-detection.

#### 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 controller

These metrics refer to the Controller.

Labels:

| Label      | Description     |
|:-----------|:----------------|
| controller_number | Controller number (index) |
| model | Controller model |
| driver_name | Controller driver (megaraid_sas or mpt3sas) |

Metrics:

| Metric | Dimensions | Unit |
|:------|:----------|:----|
| storcli.controller_health_status | healthy, unhealthy | status |
| storcli.controller_status | optimal, degraded, partially_degraded, failed | status |
| storcli.controller_bbu_status | healthy, unhealthy, na | status |

### Per physical drive

These metrics refer to the Physical Drive.

Labels:

| Label      | Description     |
|:-----------|:----------------|
| controller_number | Controller number (index) |
| enclosure_number | Enclosure number (index) |
| slot_number | Slot number (index) |
| media type | Media type (e.g. HDD) |

Metrics:

| Metric | Dimensions | Unit |
|:------|:----------|:----|
| storcli.phys_drive_errors | media, other | errors/s |
| storcli.phys_drive_predictive_failures | predictive_failures | failures/s |
| storcli.phys_drive_smart_alert_status | active, inactive | status |
| storcli.phys_drive_temperature | temperature | Celsius |

### Per bbu

These metrics refer to the Backup Battery Unit.

Labels:

| Label      | Description     |
|:-----------|:----------------|
| controller_number | Controller number (index) |
| bbu_number | BBU number (index) |
| model | BBU model |

Metrics:

| Metric | Dimensions | Unit |
|:------|:----------|:----|
| storcli.bbu_temperature | temperature | Celsius |



## Alerts


The following alerts are available:

| Alert name  | On metric | Description |
|:------------|:----------|:------------|
| [ storcli_controller_health_status ](https://github.com/netdata/netdata/blob/master/src/health/health.d/storcli.conf) | storcli.controller_health_status | RAID controller ${label:controller_number} is unhealthy |
| [ storcli_controller_bbu_status ](https://github.com/netdata/netdata/blob/master/src/health/health.d/storcli.conf) | storcli.controller_bbu_status | RAID controller ${label:controller_number} BBU is unhealthy |
| [ storcli_phys_drive_errors ](https://github.com/netdata/netdata/blob/master/src/health/health.d/storcli.conf) | storcli.phys_drive_errors | RAID physical drive c${label:controller_number}/e${label:enclosure_number}/s${label:slot_number} errors |
| [ storcli_phys_drive_predictive_failures ](https://github.com/netdata/netdata/blob/master/src/health/health.d/storcli.conf) | storcli.phys_drive_predictive_failures | RAID physical drive c${label:controller_number}/e${label:enclosure_number}/s${label:slot_number} predictive failures |


## Setup

### Prerequisites

No action required.

### Configuration

#### File

The configuration file name for this integration is `go.d/storcli.conf`.


You can edit the configuration file using the `edit-config` script from the
Netdata [config directory](/docs/netdata-agent/configuration/README.md#the-netdata-config-directory).

```bash
cd /etc/netdata 2>/dev/null || cd /opt/netdata/etc/netdata
sudo ./edit-config go.d/storcli.conf
```
#### Options

The following options can be defined globally: update_every.


<details open><summary>Config options</summary>

| Name | Description | Default | Required |
|:----|:-----------|:-------|:--------:|
| update_every | Data collection frequency. | 10 | no |
| timeout | storcli binary execution timeout. | 2 | no |

</details>

#### Examples

##### Custom update_every

Allows you to override the default data collection interval.

<details open><summary>Config</summary>

```yaml
jobs:
  - name: storcli
    update_every: 5  # Collect StorCLI RAID statistics every 5 seconds

```
</details>



## Troubleshooting

### Debug Mode

To troubleshoot issues with the `storcli` collector, run the `go.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 `go.d.plugin` to debug the collector:

  ```bash
  ./go.d.plugin -d -m storcli
  ```
