StoreCLI RAID
StoreCLI RAID
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 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 nologstorcli /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.
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.
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.
| Name | Description | Default | Required |
|---|---|---|---|
| update_every | Data collection frequency. | 10 | no |
| timeout | storcli binary execution timeout. | 2 | no |
Examples
Custom update_every
Allows you to override the default data collection interval.
jobs:
- name: storcli
update_every: 5 # Collect StorCLI RAID statistics every 5 seconds
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 | storcli.controller_health_status | RAID controller ${label:controller_number} is unhealthy |
| storcli_controller_bbu_status | storcli.controller_bbu_status | RAID controller ${label:controller_number} BBU is unhealthy |
| storcli_phys_drive_errors | storcli.phys_drive_errors | RAID physical drive c${label:controller_number}/e${label:enclosure_number}/s${label:slot_number} errors |
| storcli_phys_drive_predictive_failures | storcli.phys_drive_predictive_failures | RAID physical drive c${label:controller_number}/e${label:enclosure_number}/s${label:slot_number} predictive failures |
Troubleshooting
Debug Mode
To troubleshoot issues with the storcli collector, run the go.d.plugin with the debug option enabled. The output
should give you clues as to why the collector isn’t working.
-
Navigate to the
plugins.ddirectory, usually at/usr/libexec/netdata/plugins.d/. If that’s not the case on your system, opennetdata.confand look for thepluginssetting under[directories].cd /usr/libexec/netdata/plugins.d/ -
Switch to the
netdatauser.sudo -u netdata -s -
Run the
go.d.pluginto debug the collector:./go.d.plugin -d -m storcli
Getting Logs
If you’re encountering problems with the storcli collector, follow these steps to retrieve logs and identify potential issues:
- Run the command specific to your system (systemd, non-systemd, or Docker container).
- Examine the output for any warnings or error messages that might indicate issues. These messages should provide clues about the root cause of the problem.
System with systemd
Use the following command to view logs generated since the last Netdata service restart:
journalctl _SYSTEMD_INVOCATION_ID="$(systemctl show --value --property=InvocationID netdata)" --namespace=netdata --grep storcli
System without systemd
Locate the collector log file, typically at /var/log/netdata/collector.log, and use grep to filter for collector’s name:
grep storcli /var/log/netdata/collector.log
Note: This method shows logs from all restarts. Focus on the latest entries for troubleshooting current issues.
Docker Container
If your Netdata runs in a Docker container named “netdata” (replace if different), use this command:
docker logs netdata 2>&1 | grep storcli
