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:

Label	Description
slot	Slot number
model	Controller model

Metrics:

Metric	Dimensions	Unit
hpssa.controller_status	ok, nok	status
hpssa.controller_temperature	temperature	Celsius
hpssa.controller_cache_module_presence_status	present, not_present	status
hpssa.controller_cache_module_status	ok, nok	status
hpssa.controller_cache_module_temperature	temperature	Celsius
hpssa.controller_cache_module_battery_status	ok, nok	status

Per array

These metrics refer to the Array.

Labels:

Label	Description
slot	Slot number
array_id	Array id
interface_type	Array interface type (e.g. SATA)
array_type	Array type (e.g. Data)

Metrics:

Metric	Dimensions	Unit
hpssa.array_status	ok, nok	status

Per logical drive

These metrics refer to the Logical Drive.

Labels:

Label	Description
slot	Slot number
array_id	Array id
logical_drive_id	Logical Drive id (number)
disk_name	Disk name (e.g. /dev/sda)
drive_type	Drive type (e.g. Data)

Metrics:

Metric	Dimensions	Unit
hpssa.logical_drive_status	ok, nok	status

Per physical drive

These metrics refer to the Physical Drive.

Labels:

Label	Description
slot	Slot number
array_id	Array id or "na" if unassigned
logical_drive_id	Logical Drive id or "na" if unassigned
location	Drive location in port:box:bay format (e.g. 1I:1:1)
interface_type	Drive interface type (e.g. SATA)
drive_type	Drive type (e.g. Data Drive, Unassigned Drive)
model	Drive model

Metrics:

Metric	Dimensions	Unit
hpssa.physical_drive_status	ok, nok	status
hpssa.physical_drive_temperature	temperature	status

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

Name	Description	Default	Required
update_every	Data collection frequency.	10	no
timeout	ssacli binary execution timeout.	2	no

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

Getting Logs

If you're encountering problems with the hpssa 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 hpssa

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 hpssa /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 hpssa
