Bulk resetting SCOM monitor alerts

Question

Is there a way to bulk reset SCOM monitor alerts using a PowerShell script?

I'm responsible for server OS patching each month, and even though we use SCCM to suppress alerts during patch windows, we still get noise in SCOM which I manually recalculate to close the alerts. I want to run a script that can easily reset the monitors and provide a better picture of actual health.

Should I run this script against each of the Management Servers? I have reconciled all of the scopes, but it's not feasible to reset each alert one at a time.

Hello,

You can use a PowerShell script to bulk reset SCOM monitor alerts, reducing manual effort. Run the script from a machine with the SCOM PowerShell module installed. Connect to your SCOM management server, retrieve all active alerts, and reset each monitor state. Here’s a sample script: HPInstantInk

Import-Module OperationsManager
New-SCOMManagementGroupConnection -ComputerName "YourManagementServerName"
$activeAlerts = Get-SCOMAlert -ResolutionState 0

foreach ($alert in $activeAlerts) {
    $monitoringObject = $alert.MonitoringObject
    $monitor = $alert.Monitor
    if ($monitor -and $monitoringObject) {
        Write-Host "Resetting monitor $($monitor.DisplayName) for $($monitoringObject.DisplayName)"
        Reset-SCOMMonitoringObject -MonitoringObject $monitoringObject -Monitor $monitor
    } else {
        Write-Host "Skipping alert $($alert.Name)"
    }
}

Write-Host "Monitor reset process completed."

Run this script on a server with the appropriate permissions. Adjust the script if you need to filter alerts based on specific criteria.
