Here is a PowerShell script to discover SQL Server instances installed on the server hosts in the Host table. Please create a SQL Server Agent job for this. The domain account that this job runs under needs to in the local administrator's group on the host whose metrics it is trying to get.

This information should be fairly static. Depending on your situation, scheduling this to run weekly, monthly, or quarterly, or whatever. You can always manually kick off this job if needed.

Remember to change “sql1” to your host instance name

function getSqlInstanceName($ComputerName) {
    $SqlInstances = Get-Service -ComputerName $ComputerName | where {($_.Name -like
    'mssql$*') -or ($_.Name -eq 'mssqlserver')}
    $instanceArray = @()
    if ($SqlInstances -ne $null) {
        $SqlInstances | foreach {
			$sqlName = $_.Name
			$service = Get-WmiObject win32_service -ComputerName $ComputerName | where {$_.Name -eq $sqlName}
            if ($sqlName -eq 'mssqlserver') {
                $instanceArray = $instanceArray + @(@{InstanceName=$ComputerName; StartupAcct=$service.StartName; Status=$_.Status})}
            else {
                $instanceArray = $instanceArray + @(@{InstanceName=$ComputerName + "\" +
								$sqlName.split("$")[1];StartupAcct=$service.StartName; Status=$_.Status})}}}
    return $instanceArray}
function insertInstanceSQL($i, $HostID) {
    $InstanceName = $i.InstanceName
    $StartupAcct = $i.StartupAcct
    if ($InstanceName -ne $null) {
        if ($i.Status -eq 'running') {
            $IsActive = "Y"}
        else {$IsActive = "N"}
        $sql = "EXEC Windows.Instance_Insert $HostID, '$InstanceName', '$StartupAcct', '$IsActive'"
	return $sql}}
$HostList = Invoke-Sqlcmd -ServerInstance "sql1" -Query "EXEC
Windows.Host_Select_HostID_HostName" -Database "JiMetrics"
$HostList | foreach {
    $HostID = $_.HostID
    Try {$SqlInstances = getSqlInstanceName($_.HostName)}
    Catch {Return}
    $SqlInstances | foreach {
		$sql = insertInstanceSQL $_ $HostID
        Invoke-Sqlcmd -Query $sql -ServerInstance "sql1" -Database "JiMetrics"}}
