HP Smart Storage Arrays

Plugin: python.d.plugin Module: hpssa


This collector monitors HP Smart Storage Arrays metrics about operational statuses and temperatures.

It uses the command line tool ssacli. The exact command used is sudo -n 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


If no configuration is provided, the collector will try to execute the ssacli binary.


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 grouped by scope.

The scope defines the instance that the metric belongs to. An instance is uniquely identified by a set of labels.

Per HP Smart Storage Arrays instance

These metrics refer to the entire monitored application.

This scope has no labels.


hpssa.ctrl_statusctrl{adapter slot}_status, cache{adapter slot}status, battery{adapter slot}_status per adapterStatus
hpssa.ctrl_temperaturectrl{adapter slot}_temperature, cache{adapter slot}_temperature per adapterCelsius
hpssa.ld_statusa dimension per logical driveStatus
hpssa.pd_statusa dimension per physical driveStatus
hpssa.pd_temperaturea dimension per physical driveCelsius


There are no alerts configured by default for this integration.



Enable the hpssa collector

The hpssa collector is disabled by default. To enable it, use edit-config from the Netdata config directory, which is typically at /etc/netdata, to edit the python.d.conf file.

cd /etc/netdata   # Replace this path with your Netdata config directory, if different
sudo ./edit-config python.d.conf

Change the value of the hpssa setting to yes. Save the file and restart the Netdata Agent with sudo systemctl restart netdata, or the appropriate method for your system.

Allow user netdata to execute ssacli as root.

This module uses ssacli, which can only be executed by root. It uses sudo and assumes that it is configured such that the netdata user can execute ssacli as root without a password.

  • Add to your /etc/sudoers file:

which ssacli shows the full path to the binary.

netdata ALL=(root)       NOPASSWD: /path/to/ssacli

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 ssacli using sudo.

As the root user, do the following:

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



The configuration file name for this integration is python.d/hpssa.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 python.d/hpssa.conf


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.

Config options
update_everySets the default data collection frequency.5no
priorityControls the order of charts at the netdata dashboard.60000no
autodetection_retrySets the job re-check interval in seconds.0no
penaltyIndicates whether to apply penalty to update_every in case of failures.yesno
nameJob name. This value will overwrite the job_name value. JOBS with the same name are mutually exclusive. Only one of them will be allowed running at any time. This allows autodetection to try several alternatives and pick the one that
ssacli_pathPath to the ssacli command line utility. Configure this if ssacli is not in the $PATHno
use_sudoWhether or not to use sudo to execute ssacliTrueno


Local simple config

A basic configuration, specyfing the path to ssacli

ssacli_path: /usr/sbin/ssacli


Debug Mode

To troubleshoot issues with the hpssa 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].

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

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

    ./python.d.plugin hpssa debug trace
