Enable Hardware Health via PowerShell

Working with nickzourdos​ today on an issue he found where he needed to enable hardware health polling on ~80 devices that were pre-existing in NPM.

It should be noted that all devices are the same make/model. This is important.

Step 1: Research

Hardware Health · solarwinds/OrionSDK Wiki · GitHub

It seems we need the NetObjectID and the PollingMethod for this

Step 2: A little more research

Query SWIS via the SWQL Studio to get a sample of the PollingMethod used on an existing device

You can grab the SWQL Studio Here: Releases · solarwinds/OrionSDK · GitHub


SELECT PollingMethod, ParentObjectType, ParentObjectID FROM Orion.HardwareHealth.HardwareInfoBase WHERE ParentObjectType = 'N' AND ParentObjectID =<NodeID of Sample Node>

Step 3: Execute the below script in PowerShell, supplying the Hostname, Login to SolarWinds, PollingMethod, and Search Criteria for your nodes (Nick is a solid admin and has a very nice standard naming convention!)

        [ Parameter( Mandatory = $true, HelpMessage = "Do you want to use the credentials from PowerShell (Trusted), or a new login (Explicit)?" ) ] [ ValidateSet( 'Trusted', 'Explicit' ) ] [ string ] $ConnectionType

    # Import the SolarWinds PowerShell Module
    Import-Module SwisPowerShell

    # Connect to SWIS
    IF ( $ConnectionType -eq 'Trusted'  ) {

        $swis = Connect-Swis -Trusted -Hostname $SolarWindsServer

    ELSE {
        $creds = Get-Credential -Message "Please provide a Domain or Local Login for SolarWinds"

        $swis = Connect-Swis -Credential $creds -Hostname $SolarWindsServer


RETURN $swis

    # Set the hardware pollers for the nodes
        $results = Invoke-SwisVerb -SwisConnection $swis -EntityName Orion.HardwareHealth.HardwareInfoBase -Verb EnableHardwareHealth -Arguments @( $netObjectID, $pollingMethod )

        Write-Host "Hardware Health Enabled for: $( $nodeName )" -ForegroundColor Green



        $ErrorMessage = $_.Exception.Message
        Write-Host "The error message was $( $ErrorMessage )" -ForegroundColor Yellow



#endregion Execution

Note: If you get an error that you're missing the Module, run this in PowerShell:

Install-Module -Name SwisPowerShell

ref: PowerShell Gallery | SwisPowerShell


This applies to any type of device type?

Sort of. You can run this for any device type that is supported by Hardware Health polling. However the script is designed to be run against a single PollingMethod at a time. (Gathered from Step 2)

So, if you have 4 Cisco devices that all use polling method 9, and 2 f5s that all use polling method 12; you would run the script 2 times (one for each polling method and target nodes).

There's good information in the GitHub wiki posted in Step 1. But, there's not a solid map that I know of that can mark every single model to each polling method, so full automation wasn't the goal here.

That being said, it would be simple enough to setup some static mapping in the script by including the MachineType in the $nodeQuery variable and then using that data to evaluate against...

Something like this in theory:

If( $machineType -like '*Cisco*' ) { apply Cisco polling method }

If ( $machineType -like '*f5*' ) { apply f5 polling method }


Without having the full map of everything, this method would be limited based on the machine types you currently have and mapping existing nodes to polling methods.

Based on the relative rarity of needing this script, we decided it would be easier just to run it as needed, versus setting it up to run on a schedule filled with every possibility of polling method:machine type combinations.

Just checking out there if anyone has built one like this but with the 'DisableHardwareHealth' verb and focus not only on Node or machine type but node and sensor name?

Thanks Zack,

If anyone else is interested here is a SQL query that will disable based off the sensor name:

update [dbo].[HWH_HardwareItem] set IsDisabled = 0 where UniqueName = 'sensorname' and HardwareInfoID in (select ID from HWH_HardwareInfo where netobjecttype = 'N' and netobjectID in (select nodeid

from nodesdata where caption like '%nodename%'))
