To create an alert, complete the following steps: 1. Open Performance, and expand Performance Logs And Alerts. 2. In the console tree, select Alerts. Existing alerts are listed in the details pane. A red icon indicates an alert that is not running or has been stopped; a green icon indicates an alert that is running. 3. Right-click Alerts and select New Alert Settings from the shortcut menu. 4. In the Name text box, type the name of the alert you are creating and click OK. A Properties dialog box for configuring the alert (in this case named High Level Activity) opens. 5. Click Add on the General tab to open the Add Counters dialog box (Figure 20-12).

6. Configure the alert by specifying whether to monitor the local machine or a remote machine, choosing one or more counters, and setting threshold values for the counters. Click Add to add the alerts, and then click Close to close the Add Counters dialog box. 7. On the Action tab, select an action to perform when an alert is triggered. 8. On the Schedule tab, choose when and how the Alert log starts. (These settings are described in the next section.)

Determining workflow instance execution status 1. In the Visual Studio Solution Explorer pane, open the WorkflowHost project s Program.cs file for editing. 2. With Program.cs open in the code editor, look for the code we added in Main to start the workflow instance:

You must choose threshold values for each counter on which you set an alert. This is done on the General tab of the Properties dialog box for the alert. When you create an alert, the Properties dialog box is displayed automatically. If you need to add counters at a later date, you can access the Properties dialog box by right-clicking the name of the alert file, choosing Properties from the shortcut menu, and clicking Add on the General tab. More Info For information about specifying a computer to monitor and on selecting counters for the alert, see the section titled Selecting Counters earlier in this chapter. Thresholds trigger an alert when the value of the counter falls either above or below a baseline you ve chosen. To establish a baseline, determine the acceptable level of system performance when your system is experiencing a typical workload and running all required services. You do this by reviewing logged data graphed by System Monitor or by exporting the data and generating reports for analysis. On the Action tab of the Properties dialog box (Figure 20-13), you can specify actions that should occur when a threshold is exceeded.

System State backup is the preferred method for backing up Certificate Services. A System State backup includes the following settings related to Certificate Services:

Figure 20-13.

instance.Start();

Four options are available:

3. So that we can see the workflow instance status, we ll print the result of the workflow definition status query directly to the console. Place the following below the code we inserted in Step 2:

The CA key pair. The CA either has a self-signed certificate (in the case of a root CA) or a certificate issued by another CA in the hierarchy. The CA key pair must be backed up to ensure that you can rebuild the CA using the same key pair. This also ensures that any certificates currently issued by the CA remain valid after the CA is restored. If the CA s certificate is renewed with a new key pair, the backup must include all versions of the CA key pair.

Console.WriteLine("The workflow is: {0}", instance.GetWorkflowDefinition().ExecutionStatus.ToString());

Start Performance Data Log Runs an existing counter log. Run This Program Specifies a program to run when an alert is triggered. Click the Command Line Arguments button to add commandline arguments that provide additional information. For example, in Figure 20-14, selecting Alert Name, Counter Name, and Limit Value adds the details shown in the Example box.
