Prometheus exporter for Dell Hardware components using OMSA.

The exporter was originally made by PrFalken. Due to some issues in the code, I rewrote the whole exporter using the "node_exporter" pattern and therefore moved it from being a fork out, to a standalone repository.

Omreport parsing functions were borrowed from the Bosun project, thank you very much for that, they are the most tedious part of the job.

This exporter wraps the "omreport" command from Dell OMSA. If you can't run omreport on your system, the exporter won't export any metrics.

Tested Dell OMSA Compatibility

The dellhw_exporter has been tested with the following OMSA versions:

  • 7.4
  • 8.4
  • 9.1

Kernel Compatibility

Please note that only kernel versions that are supported by DELL DSU / OMSA tools are working!

State 07.06.2019: Dell OMSA DSU_19.05.00 is not compatible with 5.x kernel it seems (e.g., Fedora uses that kernel).

Should you run into issues when using the Docker image, please follow the Troubleshooting - No metrics being exported.


Which collectors are enabled is controlled by the --colectors.enabled flag.

Enabled by default

All collectors are enabled by default. You can disable collectors by specifying the whole list of collectors through the --collectors.enabled flag.

Name Description
chassis Overall status of chassis components.
chassis_batteries Overall status of chassis CMOS batteries.
fans Overall status of system fans.
memory System RAM DIMM status.
nics NICs connection status.
processors Overall status of CPUs.
ps Overall status of power supplies.
ps_amps_sysboard_pwr System board power usage.
storage_battery Status of storage controller backup batteries.
storage_controller Overall status of storage controllers.
storage_enclosure Overall status of storage enclosures.
storage_pdisk Overall status of physical disks.
storage_vdisk Overall status of virtual disks.
system Overall status of system components.
temps Overall temperatures (in Celsius) and status of system temperature readings.
volts Overall volts and status of power supply volt readings.

What do the metrics mean?

Most metrics returned besides temperature, volts, fans RPM count and others, are state indicators which can have the following of the four states:

  • 0 - OK, the component should be fine.
  • 1 - Critical, the component is not okay / has potentially failed / Unknown status.
  • 2 - Non-Critical, the component is not okay, but not critical.



$ dellhw_exporter --help
Usage: dellhw_exporter [OPTION]...
  -collectors.enabled string
    	Comma separated list of active collectors (default "chassis,chassis_batteries,fans,memory,nics,processors,ps,ps_amps_sysboard_pwr,storage_battery,storage_controller,storage_enclosure,storage_pdisk,storage_vdisk,system,temps,volts")
  -collectors.omr-report string
    	Path to the omReport executable (default "/opt/dell/srvadmin/bin/omreport")
    	If true, print available collectors and exit.
    	!! DEPRECATED !! Starts the Dell OpenManage start script !! DEPRECATED !!
    	Enable debug output
    	Show help menu
    	Show version information
  -web.listen-address string
    	The address to listen on for HTTP requests (default ":9137")
  -web.telemetry-path string
    	Path the metrics will be exposed under (default "/metrics")

Environment variables

For the description of the env vars, see the above equivalent flags.


Docker specific environment variables

START_DELL_SRVADMIN_SERVICES # Defaults to `true`, toggle if the srvadmin services are started inside the container

Running in Docker

The container image is available from Docker Hub and

Pull the Docker image

Docker Hub

docker pull galexrt/dellhw_exporter

docker pull

Run the Docker image

NOTE The --privileged flag is required as the OMSA needs to access the host devices.

docker run -d --name dellhw_exporter --privileged -p 9137:9137 galexrt/dellhw_exporter
# or for
docker run -d --name dellhw_exporter --privileged -p 9137:9137


Checkout the files in the contrib/monitoring/ directory.


No metrics being exported

If you are not running the Docker container, it is probably that your OMSA / srvadmin services are not running. Start them using the following commands:

/opt/dell/srvadmin/sbin/ status
/opt/dell/srvadmin/sbin/ start
echo "return code: $?"

Please note that the return code should be 0, if not please investigate the logs of srvadmin services.

When running inside the container this most of the time means Be sure to enter the container and run the following commands to verify if the kernel modules have been loaded:

/usr/libexec/instsvcdrv-helper status
lsmod | grep -iE 'dell|dsu'

Should the lsmod not contain any module named after dell_ and / or dsu_, be sure to add the following read-only mounts depending on your OS, for the kernel modules directory (/lib/modules) and / or the kernel source / headers directory (depends hardly on the OS your are using) to the dellhw_exporter Docker container using -v HOST_PATH:CONTAINER_PATH:ro flag.
