One of the things people have been asking about is what thresholds are used by various monitors. There is no bullet proof way to do this, but here is a script I wrote that would answer this question for the majority of monitors:

function GetThreshold ([String] $configuration)
{

$config = [xml] ("<config>" + $configuration + "</config>")

$threshold = $config.Config.Threshold

if($threshold -eq $null)
{
$threshold = $config.Config.MemoryThreshold
}

if($threshold -eq $null)
{
$threshold = $config.Config.CPUPercentageThreshold
}

if($threshold -eq $null)
{

if($config.Config.Threshold1 -ne $null -and $config.Config.Threshold2 -ne $null)
{
                $threshold = "first threshold is: " + $config.Config.Threshold1 + " second threshold is: " + $config.Config.Threshold2
}

}

if($threshold -eq $null)
{

if($config.Config.ThresholdWarnSec -ne $null -and $config.Config.ThresholdErrorSec -ne $null)
{
 $threshold = "warning threshold is: " + $config.Config.ThresholdWarnSec + " error threshold is: " + $config.Config.ThresholdErrorSec 
}

}

if($threshold -eq $null)
{
                if($config.Config.LearningAndBaseliningSettings -ne $null)
                {             
                                $threshold = "no threshold (baseline monitor)"
                }
}

return $threshold

}

$perfMonitors = get-monitor -Criteria:"IsUnitMonitor=1 and Category='PerformanceHealth'"

$perfMonitors | select-object @{name="Target";expression={foreach-object {(Get-MonitoringClass -Id:$_.Target.Id).DisplayName}}},DisplayName, @{name="Threshold";expression={foreach-object {GetThreshold $_.Configuration}}}, @{name="AlertOnState";expression={foreach-object {$_.AlertSettings.AlertOnState}}}, @{name="AutoResolveAlert";expression={foreach-object {$_.AlertSettings.AutoResolve}}}, @{name="AlertSeverity";expression={foreach-object {$_.AlertSettings.AlertSeverity}}} | sort Target, DisplayName | export-csv "c:\monitor_thresholds.csv"

The output of this script is a csv file with the following columns:

Type - the type of objects the monitor is targeted to

DisplayName - the display name of the monitor

Threshold - the threshold used by the monitor

AlertOnState - whether the monitor generates an alert when its state changes

AutoResolveAlert - whether the generated alert will be autoresolved when the monitor state goes back to green

AlertSeverity - the severity of the generated alert
