INTRODUCTION


In Microsoft System Center Operations Manager alerts can be raised by the monitors. Alerts that are raised by the monitors are typically the result of a state change. These alerts are displayed in the Operations console similar to the alerts that are raised by rules. However, these alerts should not be manually resolved. 

More Information


Alerts that are raised by the monitors are related to a state change. These alerts should be resolved by the monitor itself. For example, the monitor waits for when the state changes back to Success or green. Alerts can be manually resolved in the Operations console. However, we do not recommend that you manually resolve the alerts. If the alert is manually resolved, the resolved state of the alert does not match the state of the monitored object.

You can use some Windows PowerShell cmdlets to determine whether an alert is raised by a monitor. The following is a sample of a script that determines whether an alert is raised by a monitor:
#get all alerts
$alerts = get-alert

#get only alerts generated by a monitor and not closed $alerts = get-alert | where {$_.IsMonitorAlert -eq $true -and $_.ResolutionState -ne 255}

#format a table with alert info
$alert | sort-object LastModified, Name | ft Name, LastModified

#print number of alerts
$alerts.Count

#get only alerts generated by a rule and not closed $alerts = get-alert | where {$_.IsMonitorAlert -eq $false -and $_.ResolutionState -ne 255}
