HPE Smart Arrays

Plugin: go.d.plugin Module: hpssa

Overview

Monitors the health of HPE Smart Arrays by tracking the status of controllers, arrays, logical and physical drives in your storage system. It relies on the ssacli 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:

  • ssacli ctrl all show config detail

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:

LabelDescription
slotSlot number
modelController model

Metrics:

MetricDimensionsUnit
hpssa.controller_statusok, nokstatus
hpssa.controller_temperaturetemperatureCelsius
hpssa.controller_cache_module_presence_statuspresent, not_presentstatus
hpssa.controller_cache_module_statusok, nokstatus
hpssa.controller_cache_module_temperaturetemperatureCelsius
hpssa.controller_cache_module_battery_statusok, nokstatus

Per array

These metrics refer to the Array.

Labels:

LabelDescription
slotSlot number
array_idArray id
interface_typeArray interface type (e.g. SATA)
array_typeArray type (e.g. Data)

Metrics:

MetricDimensionsUnit
hpssa.array_statusok, nokstatus

Per logical drive

These metrics refer to the Logical Drive.

Labels:

LabelDescription
slotSlot number
array_idArray id
logical_drive_idLogical Drive id (number)
disk_nameDisk name (e.g. /dev/sda)
drive_typeDrive type (e.g. Data)

Metrics:

MetricDimensionsUnit
hpssa.logical_drive_statusok, nokstatus

Per physical drive

These metrics refer to the Physical Drive.

Labels:

LabelDescription
slotSlot number
array_idArray id or "na" if unassigned
logical_drive_idLogical Drive id or "na" if unassigned
locationDrive location in port:box:bay format (e.g. 1I:1:1)
interface_typeDrive interface type (e.g. SATA)
drive_typeDrive type (e.g. Data Drive, Unassigned Drive)
modelDrive model

Metrics:

MetricDimensionsUnit
hpssa.physical_drive_statusok, nokstatus
hpssa.physical_drive_temperaturetemperaturestatus

Alerts

There are no alerts configured by default for this integration.

Setup

Prerequisites

Install ssacli

See official installation instructions.

Configuration

File

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

Options

The following options can be defined globally: update_every.

Config options
NameDescriptionDefaultRequired
update_everyData collection frequency.10no
timeoutssacli binary execution timeout.2no

Examples

Custom update_every

Allows you to override the default data collection interval.

Config
jobs:
- name: hpssa
update_every: 5 # Collect HPE Smart Array statistics every 5 seconds

Troubleshooting

Debug Mode

To troubleshoot issues with the hpssa 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].

    cd /usr/libexec/netdata/plugins.d/
  • Switch to the netdata user.

    sudo -u netdata -s
  • Run the go.d.plugin to debug the collector:

    ./go.d.plugin -d -m hpssa
