01-06-2021

What is Performance Monitor? Many times it occurs that our computer just ceases to respond, shuts down unexpectedly or behaves abnormally. There could be a number of reasons for such behavior and pointing out the exact reason could be of great help. Windows has a tool named Performance Monitor, which you can use for this purpose. With this tool, you can keep a check on the performance of your system and identify how different programs affect the system performance. You can analyze data related to your processor, memory, network, hard drive, etc. It can tell you how the system resources are managed and other configuration information that might be useful for you. It can also collect and log the data in files, which can be analyzed later. Read on to see how you can use Performance Monitor to fix performance related issues in Windows 10.

When you first open Performance Monitor, you will see the overview and system summary.

Now, from the left pane, select ‘Performance Monitor’ under ‘Monitoring Tools’. The graph you see here is the processor time over last 100 seconds. The horizontal axis displays time and the vertical axis displays the percentage of time your processor consumes working on the active programs.

Apart from the ‘Processor Time’ counter, you can also analyze many other counters.

How to add new counters under Performance Monitor

1.Click on the green plus shaped icon on top of the graph.

2.The Add Counters window will open.

3.Now, select the name of your computer (usually it is a local computer) in the ‘Select counters from computer’ drop-down menu.

4.Now, expand the category of counters you want, say Processor.

5.Select one or more counters from the list. To add more than one counters, select the first counter, then press down the Ctrl key while selecting the counters.

6.Select the instances of the selected object(s) if possible.

7.Click on Add button to add the counters. The added counters will be shown on the right side.

8.Click on OK to confirm.

9.You will see that the new counters start to appear in the graph with different colors.

10.The details of each counter will be shown at the bottom, like which colors correspond to it, its scale, instance, object, etc.

11.Use the checkbox against each to counter to show or hide it from the graph.

12.You can add more counters by following the same steps as given above.

Once you have added all the desired counters, it is time to customize them.

How to Customize the Counter View in Performance Monitor

1.Double-click on any counter below the graph.

2.To select more than one counters, press down Ctrl key while selecting the counters. Then right-click and select Properties from the list.

3.Performance Monitor Properties window will open, from there switch to the ‘Data’ tab.

4.Here you can select the color, scale, width, and style of the counter.

5.Click on Apply followed by OK.

An important thing to note here is that when you restart performance monitor, all these set counters and configurations will be lost by default. To save these configurations, right-click on the graph and select ‘Save settings as’ from the menu.

Type the desired file name and click on Save. The file will be saved as a .htm file. Once saved, there are two ways of loading the saved file for later use,

  1. Right-click on the saved file and select Internet Explorer as the ‘Open with’ program.
  2. You will be able to see the performance monitor graph in the internet explorer window.
  3. If you don’t see the graph already, click on ‘Allow blocked content’ in the popup.

Another way to load it is by pasting counter list. However, this method may not work for some of the users.

  1. Open the saved file using notepad and copy its contents.
  2. Now open Performance Monitor by using the steps given before and click on ‘Paste Counter list’ icon on top of the graph.

The third icon above the graph is for changing graph type. Click on the downward arrow beside it to select the type of graph. You can choose from line, histogram bar or report. You can also press Ctrl + G to switch between the graph types. The screenshots shown above correspond to the line graph. The histogram bar looks like this:

The report will look like this:

The pause button on the toolbar will allow you to freeze the constantly changing graph at any instance, if you want to analyze it. You can resume by clicking on the play button.

Some Common Performance Counters

Processor:

  • % Processor Time: This is the percentage of time spent by the processor in executing a non-idle thread. If this percentage stays over 80% constantly, it means it is difficult for your processor to handle all the processes.
  • % Interrupt Time: This is the time required by your processor to receive and service hardware requests or interrupts. If this time exceeds 30%, there might be some hardware related risk.

Memory:

  • % Committed Bytes In Use: This counter shows what percentage of your RAM is currently in use or is committed. This counter should fluctuate values as different programs are opened and closed. But if it keeps on increasing, there might be a memory leak.
  • Available Bytes: This counter depicts the amount of physical memory (in Bytes) that are available for immediately allocating it to a process or system. A less than 5% of available bytes means you have very less memory free and may need to add more memory.
  • Cache Bytes: This counter tracks the part of system cache which is currently active in physical memory.

Paging File:

  • % Usage: This counter tells the percentage of current pagefile in use. It should not be higher than 10%.

PhysicalDisk:

  • % Disk Time: This counter monitors the time taken by a drive to process read and write requests. This should not be too high.
  • Disk Read Bytes/sec: This counter maps the rate at which bytes are transferred from the disk during the read operations.
  • Disk Write Bytes/sec: This counter maps the rate at which bytes are transferred to the disk during write operations.

Network Interface:

  • Bytes Received/sec: It represents the rate of bytes being received over each network adapter.
  • Bytes Sent/sec: It represents the rate of bytes being sent over each network adapter.
  • Bytes Total/sec: It includes both Bytes Received and Bytes Sent.
    If this percentage lies between 40%-65%, you should be cautious. For over 65%, the performance will be adversely affected.

Thread:

  • % Processor Time: It tracks the amount of processor’s effort which is used by an individual thread.

How to Create a Data Collector Sets

A data collector set is a combination of one or more performance counters which can be saved to collect data over a period of time or on demand. These are especially useful when you want to monitor a component of your system over a specified time period, for instance, every month. There are two predefined sets available,

System Diagnostics: This data collector set can be used troubleshooting issues related to driver failures, faulty hardware, etc. It includes data collected from System Performance along with other detailed system information.

System Performance: This data collector set can be used to handle performance related issues like a slow computer. It collects data related to memory, processor, disk, network performance, etc.

To access these, expand ‘Data Collector Sets’ in the left pane on Performance Monitor window and click on System.
