Revisions

The Microsoft System Center team has validated this procedure as of the original revision.  We will continue to review any changes and periodically provide validations on later revisions as they are made.  Please feel free to make any corrections or additions to this procedure that you think would assist other users

Sample Code

A sample of the completed code for each exercise is available in the TechNet Gallery.  There is a separate sample for each exercise that includes the management pack completed at the end of that exercise and each preceding exercise.  This strategy allows you to work through each exercise in order and then compare your results.  For VSAE, this also includes the Visual Studio solution. 

Details

The workflows created in this procedure have the following characteristics:

  • Rule and monitor targeted at a class that has multiple instances on an agent. Because there are multiple instances, cookdown support is required.
  • The rule collects a performance value from the script while the monitor sets its state based on the comparison of the script value to specified threshold values.
  • The monitor does not support On Demand Discovery so that it does not require that you use a probe action module to run the script.
  • The script accepts arguments for the computer name of the target object’s agent and the version of the application.
  • The script itself is only a test that generates a constant value.

    8. In the TimeoutSeconds box, type 300.
    9. Click the Edit… button. This starts the custom editor.
    10. Paste the complete contents of the following script between the ScriptBody tags in the XML. Replace any text that might already exist:

             
      <![CDATA[
      sComputerName = WScript.Arguments(0)
      sVersion = WScript.Arguments(1)
      Set oAPI = CreateObject("MOM.ScriptAPI")
      oAPI.LogScriptEvent "MyCookdownScript.vbs",10,4, "Running script on " & sComputerName & ". Version is " & sVersion
       
      For i = 1 to 3

Visual Studio Authoring Extensions Procedure

Create data source module to run script on schedule

The first data source module will run the script and map its output to performance data.  The script is intended to return data for each instance of the target class.  In the case of this example, the script just returns three property bags to illustrate the concept. 

Since the values for the parameters provided to the module will be the same for all instances, the module is able to cookdown.  It runs only one instance of the script but returns multiple performance data items.  Each data item includes the name of the component so that we know which component each data item belongs to.

  1. Create the script:
    1. In Solution Explorer, expand the Composition folder.
    2. Right click the Composition folder, select Add and then select New Item.
    3. Select VBScript File.
    4. Change the name of the script to MyCookdownScript.vbs and click Add.
    5. Right-click MyCookdownScript.vbs and select Open.
    6. Copy the following code into the script window:

      sComputerName = WScript.Arguments(0)
      sVersion = WScript.Arguments(1)
      Set oAPI = CreateObject("MOM.ScriptAPI")
      oAPI.LogScriptEvent "MyCookdownScript.vbs",10,4, "Running script on " & sComputerName & ". Version is " & sVersion
       
      For i = 1 to 3
         Set oBag = oAPI.CreatePropertyBag()
         Call oBag.AddValue("ComputerName",sComputerName)
         Call oBag.AddValue("ComponentName","Component" & i)
         Call oBag.AddValue("Value",30)
         oAPI.AddItem(oBag)
      Next
       
      oAPI.ReturnItems
                    
                     
       
    7. Select File, and then click Save MyCookdownScript.vbs.
  2. Create the Data Source module. 
    1. Right click MyTransactionModules.mpx and select Open.
    2. Copy the following XML into the configuration window after the last <DataSourceModuleType>.  Note that you can use Intellisense to manually type in each entry.

      <DataSourceModuleType ID="MyMP.DataSourceModule.MyPerformanceScriptTimed" Accessibility="Internal" Batching="false">

        <OutputType>Perf!System.Performance.Data</OutputType>
      </DataSourceModuleType>

           

Create Data Source Module to Filter on Instance

The second data source module gets the performance data from the first data source module and filters it for a single instance.  This module will output a single performance data item for a particular component. 

This module will not cookdown because a different value is provided to the ComponentName parameter for each instance of the target class.  This is a lightweight module though, so the effect of this is minimal.  The significant overhead comes from the script run from the first data source module, and that script will cookdown.

  1. Copy the following XML into the configuration window after the last <DataSourceModuleType>.  Note that you can use Intellisense to manually type in each entry.

Create Custom Monitor Type Using Custom Data Source

The monitor type calls the data source module and defines the logic for determining different health states. 

  1. Create the Monitor Type.  This includes the health states and the configuration parameters for the monitor.  Copy the following XML into the configuration window after the last <MonitorType> tag.  Note that you can use Intellisense to manually type in each entry:
        
      
    <UnitMonitorType ID="MyMP.MyApplicationComponentMonitorType" Accessibility="Internal">
      <MonitorTypeStates>
        <MonitorTypeState ID="UnderThreshold" NoDetection="false" />
        <MonitorTypeState ID="OverWarningThreshold" NoDetection="false" />
        <MonitorTypeState ID="OverErrorThreshold" NoDetection="false" />
      </MonitorTypeStates>
      <Configuration>
        <xsd:element minOccurs="1" name="IntervalSeconds" type="xsd:integer" />
        <xsd:element minOccurs="0" name="SyncTime" type="xsd:string" />
        <xsd:element minOccurs="1" name="ComputerName" type="xsd:string" />
        <xsd:element minOccurs="1" name="Version" type="xsd:string" />
        <xsd:element minOccurs="1" name="ComponentName" type="xsd:string" />
        <xsd:element minOccurs="1" name="WarningThreshold" type="xsd:integer" />
        <xsd:element minOccurs="1" name="ErrorThreshold" type="xsd:integer" />
      </Configuration>
      <OverrideableParameters>
        <OverrideableParameter ID="IntervalSeconds" Selector="$Config/IntervalSeconds$" ParameterType="int" />
        <OverrideableParameter ID="SyncTIme" Selector="$Config/SyncTime$" ParameterType="string" />
        <OverrideableParameter ID="WarningThreshold" Selector="$Config/WarningThreshold$" ParameterType="int" />
        <OverrideableParameter ID="ErrorThreshold" Selector="$Config/ErrorThreshold$" ParameterType="int" />
      </OverrideableParameters>
    </UnitMonitorType>

      
  2. Add the Data Source Module to the Monitor Type.  The values of the configuration parameters provided by the monitor are passed to the module.  Copy the following XML into the configuration window after the ending </OverideableParameters> tag.  Note that you can use Intellisense to manually type in each entry:

    <MonitorImplementation>
      <MemberModules>
        <DataSource ID="DataSource" TypeID="MyMP.DataSourceModule.MyPerformanceScriptFiltered">
          <IntervalSeconds>$Config/IntervalSeconds$</IntervalSeconds>
          <ComputerName>$Config/ComputerName$</ComputerName>
          <Version>$Config/Version$</Version>
          <ComponentName>$Config/ComponentName$</ComponentName>
        </DataSource>
      </MemberModules>
    </MonitorImplementation>

          
     

  3. Add Condition Detection modules to the Monitor Type for each of the health states.  These include an expression that defines the criteria based on output from the script.  Copy the following XML into the configuration window after the <DataSource> module.  Note that you can use Intellisense to manually type in each entry:
    <ConditionDetection ID="FilterUnderThreshold" TypeID="System!System.ExpressionFilter">
      <Expression>
        <SimpleExpression>
          <ValueExpression>
            <XPathQuery Type="Integer">Value</XPathQuery>
          </ValueExpression>
          <Operator>Less</Operator>
          <ValueExpression>
            <Value Type="Integer">$Config/WarningThreshold$</Value>
          </ValueExpression>
        </SimpleExpression>
      </Expression>
    </ConditionDetection>
    <ConditionDetection ID="FilterOverWarningThreshold" TypeID="System!System.ExpressionFilter">
      <Expression>
        <SimpleExpression>
          <ValueExpression>
            <XPathQuery Type="Integer">Value</XPathQuery>
          </ValueExpression>
          <Operator>GreaterEqual</Operator>
          <ValueExpression>
            <Value Type="Integer">$Config/WarningThreshold$</Value>
          </ValueExpression>
        </SimpleExpression>
      </Expression>
    </ConditionDetection>
    <ConditionDetection ID="FilterOverErrorThreshold" TypeID="System!System.ExpressionFilter">
      <Expression>
        <SimpleExpression>
          <ValueExpression>
            <XPathQuery Type="Integer">Value</XPathQuery>
          </ValueExpression>
          <Operator>GreaterEqual</Operator>
          <ValueExpression>
            <Value Type="Integer">$Config/ErrorThreshold$</Value>
          </ValueExpression>
        </SimpleExpression>
      </Expression>
    </ConditionDetection>

     

  4. Add Regular Detection to the Monitor Type.  This defines the modules that are run to determine each health state.  The module in the innermost node is run first followed by the others in the detection. Copy the following XML into the configuration window after the closing </MemberModules> tag.  Note that you can use Intellisense to manually type in each entry:

    <RegularDetections>
      <RegularDetection MonitorTypeStateID="UnderThreshold">
        <Node ID="FilterUnderThreshold">
          <Node ID="DataSource" />
        </Node>
      </RegularDetection>
      <RegularDetection MonitorTypeStateID="OverWarningThreshold">
        <Node ID="FilterOverWarningThreshold">
          <Node ID="DataSource" />
        </Node>
      </RegularDetection>
      <RegularDetection MonitorTypeStateID="OverErrorThreshold">
        <Node ID="FilterOverErrorThreshold">
          <Node ID="DataSource" />
        </Node>
      </RegularDetection>
    </RegularDetections>
