OpsMgr: Sample Speedometer Gauge Widget Template

This blog post features a sample management pack that consist of a widget template that allows the user to create custom Speedometer Gauge widgets from the output of PowerShell scripts via a UI within a dashboard layout in the OpsMgr 2012 Operations Console. 

This sample management pack library can now be downloaded from the TechNet Gallery. 

This Speedometer Gauge Widget template is defined in a management pack with a display name of Sample Speedometer Gauge Widget Component Library and importing the management pack into a OpsMgr 2012 R2 environment will allow the widget template to appear under the "All Templates/WeiOutThere Speedometer Gauge" folder in the "New Dashboard and Widget Wizard" page:

To create an instance of this custom Speedometer Gauge widget, first create a dashboard layout (with n-cells), Click to add widget on a cell, then select the Sample Speedometer Gauge Widget template, go through the UI pages of the template and enter the required information.

1. On the “General Properties” page, enter a name for the widget.

   

2. On the "PowerShell Script" page, the page is already pre-filled with a sample script that consist of all the key properties that utilizes the ScriptContext helper object ( $dataObject = $ScriptContext.CreateFromObject ... ), to control the display on the Speedometer Gauge widget.

   

   The following picture shows the mapping between the key properties in the script and the corresponding part on the Speedometer Gauge widget that they control:

   

3. On the “Refresh Interval” page, enter a numerical value for the refresh interval of the widget (in seconds).
   Note that the default refresh interval for the Speedometer Gauge widget is set at 300 seconds (i.e. refreshes every 5 minutes).

   

4. On the “Additional Information” page, enter an additional note for the Speedometer Gauge widget if applicable, or leave it blank.

   

5. Click the Finish button to create the custom Speedometer Gauge widget.

   

Alternatively, the $globalSelectedItems variable can also be used to pass context to a Speedometer Gauge Widget.

Here is an example of a custom Speedometer Gauge Widget utilizing the $globalSelectedItems variable to pass context from objects listed in a State Widget, with the sample script as follows:

############################################################################################################

Param( $globalSelectedItems)

#Create data object
$dataObject = $ScriptContext.CreateInstance("xsd://Speedo!val/stat")
$dataObject["Id"] = "ObjectID"

foreach ($globalSelectedItem in $globalSelectedItems) {

#Get The Name of the selected object
$selectedObjectId = $globalSelectedItem["Id"]
}

$selectedobject = get-scomclassinstance -Id $selectedObjectId

$class = get-scomclass -Name Microsoft.Windows.Server.OperatingSystem

#Look for OS instance of server
$selectedserverOS = Get-SCOMClassInstance -class $class | where Path -eq $selectedobject."[Microsoft.Windows.Computer].PrincipalName"

#Last 3 hours UTC
$aggregationInterval = 3
$dt = New-TimeSpan -hour $aggregationInterval
$nowlocal = Get-Date
#Convert local time to UTC time
$now = $nowlocal.ToUniversalTime()
$from = $now.Subtract($dt)

$perfRules = $selectedserverOS.GetMonitoringPerformanceData()

foreach ($perfRule in $perfRules)
{
#Get % Memory Used Stat
if($perfRule.CounterName -eq "PercentMemoryUsed") {
$data = $perfRule.GetValues($from, $now) | % { $_.SampleValue } | Measure-Object –Average  

     $MemState = [math]::round($data.Average,2)

#Assign % Memory Used Stat to the Value field of the Speedometer Gauge
$dataObject["Value"] = $MemState
}
}

$dataObject["Minimum"] = "0"
$dataObject["Maximum"] = "100"
$dataObject["FormatString"] = "P"

#Threshold and Target/Goal
$dataObject["Goal"] = "50"
$dataObject["ThresholdEndPointTarget"] = "50"

#Red Color Code
$dataObject["ThresholdColorTarget"] = "#9BBC24"
$dataObject["ThresholdEndPointFull"] = "100"

#Green Color Code
$dataObject["ThresholdColorFull"] = "#BC4524"

#Return the data object collection to the Speedometer Gauge
$ScriptContext.ReturnCollection.Add($dataObject)

  How can this be altered to look at CPU Usage?I tried changing the $perRule.CounterName - eq "% Processor Time"but that's not pulling any information.I'm sure I'm missing something here or maybe not using the correct performance rule

    I'm not sure what I did wrong previously, but this time it worked, so now the gauge works for mem and cpu, now a question I have, I been looking at the code, but its eluding me, I would like to add a 3rd color, say yellow or orange for a "warning" levelfor example, if I wanted it to be green till it hits 80% then turn yellow, and when it hits 90% turn red. How can I add this additional functionality?

      That would require a 3 state speedometer gauge that has to be pre-declared in the XML definition for the widget.
