Also, using the E switch with -Y allows performance monitoring of striped disk sets. Shut down and restart the system. The disk counters are not available to be tracked in Performance Monitor. You can change certain display options to better organize the Performance Monitor's various graphical interfaces. You can perform actions such as hiding the menu and title bar, the toolbar, and the status bar.
Hiding these items enables you to have a larger viewing area for your monitored data. To hide or show the menu and title bar, toolbar, or status bar of Performance Monitor, do the following:.
Choose Options from the Performance Monitor menu. In the menu, items that are shown in the Performance Monitor window have a check mark beside the menu item. To hide an item that has a check mark beside it, select that item.
To show the items after they are hidden, perform steps 2 and 3 so the item has the check mark beside it. If the title bar and menu bar are hidden, you can show those items by double-clicking on a non-text area of the window.
If the title bar and menu bar are shown, you can hide them by double-clicking in a non-text area in the Performance Monitor window. I would like to receive exclusive offers and hear about products from InformIT and its family of brands.

This view enables you to view the monitored items over a short period of time as short as every second by choosing the options from within the dialog boxes available in this view.
This view is best for actively watching the performance of a Windows XP system, as shown in Figure 1. Alert view. This view enables you to monitor the system in the background while working with other applications. You can define a threshold for a counter and, if it is reached, an alert will be triggered. The form of the alert can be specified to switch to the Alert view, log the event, or send an alert message directly to the person whose system is experiencing the alert condition.
Counter and Trace log. These log views enables Performance Monitor to record the selected counters into a file, known as a log file, while the user runs applications on the Windows system. The log file can later be examined to find potential and existing bottlenecks. Report view. Using the View Report icon in the main Performance Monitor window, the objects and counters defined in the Performance Monitor Chart view is provided in tabular view.
Figure 2 shows an example of the View Report icon selected in the main Performance Monitor window. Figure 2 -Using the Report view to describe the performance of a workstation. As you can see from the series of counters included in Windows XP Professional and Server, the Performance Monitor can actively track the performance of many aspects of a workstation.
Performance Monitor categorizes them into objects. These object types relate to actual devices, sections of memory, or processes. Objects contain items known as counters, which are the specific items to be measured using Performance Monitor. Object types also can have several instances. Instances do not already appear as objects per se, but object types such as the Processor object have an instance for each processor in a workstation or server.
Instances represent an individual object out of multiple objects of the same type. To begin monitoring a Windows XP Professional-based workstation, you need to add counters to monitor system performance.
You'll see that adding counters are identical no matter which of the four views in Performance Monitor are being used. To add counters in Performance Monitor, do the following:.
Launch Performance Monitor either from the command line or from within Control Panel in Windows Figure 3 shows an example of the Add Counters dialog box. Figure 3 -Using the Add Counters dialog box. In the Counter list, select a counter you want to track. If you are unsure of what a counter does and want more information on the specific object: counter relationship, select the counter and click once on the Explain button. The Explain button defines the purpose of the counter.
The Explain dialog box is also detached from the main dialog box as well, which makes it possible to move and copy the definition for use by other members of your team in learning how object: counter relationships work. If multiple objects exist in the Instance list, select the instance of the object you want to monitor.
Click Done after you have added all of the counters you want to monitor. This closes the Add to window. Under instances of Selected objects select the specific volume drive where the journal files are located ie C: and click "Add".
This will list all LogicalDisk performance counters associated with activity on the specified volume drive. You will see something like the following in the Added Counters window:.
The data set ie Task Set should now appear in the left hand pane. Right click and select "Properties". This would be specific to the customers working practices, for example if the issue under investigation is seen commonly at the start of normal office hours the schedule should be set for Monday - Friday commencing at am.
You can start data collection by clicking on the DataSet ie Task Set right click and press start. All "LogicalDisk" perfmon metrics are useful for analysis but the following are particularly interesting. Current Disk Queue Length is the number of requests outstanding on the disk at the time the performance data is collected. There is a very long list of counters in Windows XP. To make it easy to identify, they are listed by "Performance Object". Once you selected the object, select the counter to be monitored.
You can click on the button :"Explain" to get more information about a specific counter.
