Microsoft Windows Server 2003 Inside Out When you are finished configuring counters to view, click Close, and then click OK. In System Monitor, use the View Graph, View Histogram, and View Report options on the toolbar to display performance information based on the counters selected.

You can examine trace log data by using the Tracerpt command-line utility. Tracerpt processes trace logs and allows you to generate trace analysis reports and comma-delimited text files for the events generated. The parameters for Tracerpt are summarized in Table 16-3.

Table 16-3.

Sets the text output file to which the parsed data should be written in comma-delimited format. The default is Dumpfile.csv. Sets the name of the text file to which a summary report of the data should be written. The default is Summary.txt. Sets the name of the text file to which a detailed report of the data should be written. The default is Workload.txt.

o [filename]

summary [filename]

report [filename]

rt <session_name [session_name ...]> Sets the real-time event trace session data source to use instead of a converted log file. config <filename> y Specifies a settings file containing command options. Answers Yes to all questions without prompting.

The most basic way to use Tracerpt is to specify the name of the trace log to use. By default trace logs are written to C:\PerfLogs, so if a log in this directory was named SysP_000002.etl, you could analyze it by typing the following:

Here, three files are created in the current directory: The parsed output is written to Dumpfile.csv, a summary report is written to Summary.txt, and a detailed report is written to Workload.txt.

Comprehensive Performance Analysis and Logging You could also specify the exact files to use for output as shown in the following example:

tracerpt C:\Perflogs\ SysP_000002.etl -o c:\sysp.csv -summary c:\sysp-summary.txt -report sysp-report-.txt

You can use performance alerts to notify you and others when certain events occur or when certain performance thresholds are reached. You can also use performance alerts to generate events that are logged in the Application event log and to start applications and performance logs. After you select the Alerts node in the left pane of Performance Monitor, you should see a list of current alerts (if any) in the right pane. A green log symbol next to an alert, as shown in the following screen, indicates it is active. A red log symbol indicates the alert is inactive and won t be triggered even if the performance alert condition is reached.

You can manage an existing alert by right-clicking its entry in the right pane and then selecting one of the available shortcut options. Choose Delete to delete the alert. Choose Properties to display the alert s Properties dialog box. Choose Start to activate the alert. Choose Stop to stop the alert. Choose Save Settings As to save the alert configuration as a Web page that can be viewed in a browser, such as Internet Explorer, or imported into a new alert by using the New Alert Settings From option. You can create a new alert by right-clicking in the right pane and selecting New Alert Settings from the shortcut menu. A New Alert Settings dialog box is displayed asking you to name the new alert. Type a descriptive name here before continuing, and then click OK. A Properties dialog box similar to the one in Figure 16-11 is displayed.

Figure 16-11. Create a new alert by adding counters and setting the alert conditions for those counters.

Click Add to display the Add Counters dialog box, then add the counters for which you want to define alert conditions. When you are finished, click Close to return to the Properties dialog box of the alert. In the Counters panel, select the first counter, and then use the Alert When Value Is box to specify when an alert for this counter is triggered. Alerts can be triggered when the counter is over or under a specific value. Select Over or Under, and then set the trigger value. The unit of measurement is whatever makes sense for the currently selected counter(s). For example, to alert if the available megabytes of memory is less than 50, you would select Under and then type 50. Repeat this process to configure other counters you ve selected. In the Sample Data Every box, type in a sample interval, and select a time unit in seconds, minutes, hours, or days. The sample interval specifies how frequently the alert condition is checked for. By default, each counter will be sampled once every 5 seconds. Because you don t want to overburden the system by checking alert conditions, you should set a sampling interval that makes the most sense given the counters you are tracking and the load on the system. In the Run As box, type the name of the account under which the counter log will run, and then click Set Password. After you type the password for the account and then confirm the password, click OK to close the Set Password dialog box. To run alert logging under the default account, Network Service, type <Default>.
