How to use Resmon or Resource Monitor in Windows 11/10

Under the CPU tab, it is possible to filter each view of the given tabs by the process. Simply check the box for that process, and the bottom window will only show the activity for that process. With no processes selected, the bottom windows will transform into an activity page for all active processes. The numeric scale for the graphs on the right will change as activity changes. On the right side, you will see the usage graphs that will help you monitor the CPUs.

How to Use Resource Monitor

Resource Monitor displays real-time feeds of data about the critical systems of your PC. It’s a free utility that comes bundled with Windows 7 and Vista, and it’s very useful for monitoring your computer’s health and troubleshooting performance problems. To open Resource Monitor:

1. Press Ctrl-Shift-Esc) to open Task Manager.

2. Click the Performance tab.

3. Click the Resource Monitor button in the bottom right of the screen.

Resource Monitor looks slightly different in Windows 7 from how it looks in Windows Vista, but its basic functions are unchanged.

Overview

The Overview section provides a self-updating line graph for each of the four subsections: CPU, Disk, Network, and Memory. In Windows 7, you can also check the box next to a CPU process and see details related to that process alone. If you see a constant high level of unexpected activity in any these graphs, you a malfunctioning program or malware may be resopnsible. To troubleshoot, explore the other sections in Resource Monitor.

CPU

In Windows 7, the CPU section contains four subsections: Processes, Services, Associated Handles, and Associated Modules.

1. You can sort processes by clicking any of the column headings under Processes. Processes listed in red are nonresponsive; you can terminate them by right-clicking and choosing End Process from the context menu.

2. Try sorting the processes by Average CPU. Check the box next to any CPU-hogging entries to bring up detailed information in the other subsections.

3. Use the information you see to figure out where power-hungry processes are hiding.

Windows Vista allows you to view and sort processes as well, but it does not include the detailed subsections that Windows 7 provides.

Disk

The Disk section reveals where activity is occurring on your hard disk drive. If your hard disk activity light remains lit up constantly, this section will help you figure out the cause(s). In Windows 7, Resource Monitor will also show which processes are associated with disk activity and allow you to terminate them.

Network

The Network section displays details about network activity. If you’re using Windows 7, pay special attention to the first subsection, ‘Processes with Network Activity’. To diagnose slow network performance, sort and highlight entries on this list to find out what is hogging your bandwidth. In Vista, the available details are more limited, but you can still sort and terminate processes.

Memory

The Memory section shows you the processes that are using physical memory (RAM). Sort by Commit to see which programs are most memory-intensive. The higher the percentage of used physical memory is, the more likely you’ll be to see high numbers of Hard Faults/sec. A hard fault occurs when Windows has to access the swap file–reserved hard disk space used when RAM runs out. Despite their name, hard faults are not errors. But if your system is experiencing hundreds of hard faults per second, either you need a RAM upgrade or a process is hogging resources.

Follow these steps and you’ll soon be using the Resource Monitor with aplomb. Be sure to check back every few months and repeat the process to ensure that your PC is running error-free at optimum efficiency.

How to use Resmon or Resource Monitor in Windows 11/10

Resource Monitor is a useful tool in Windows 11/10 that helps us find how much resources are being put to use or used over time through a graphical representation. This way, it helps us check the performance counters of specific resources and decide on a course of action to improve the performance. There are many ways via which you can launch Resource Monitor and use the application for tracing the Performance Data.

How to use Resource Monitor in Windows 11/10

Resource Monitor or Resmon lets you easily monitor your CPU usage, memory usage, Disk Activity, Network Activity and more. Like the Reliability Monitor or the Performance Monitor, the Resource Monitor too is a useful built-in tool in Windows.

To launch Resource Monitor, type resmon in Start Search and hit Enter. When you first launch the application, an ‘Overview’ tab gets displayed.

1] Overview tab

• CPU
• Memory
• Disk
• Network

You can take a look at the base graphs for each of the four categories. It offers at-a-glance, basic overview of your system’s current status.

As you can see, the CPU graph displays the total percentage of CPU capacity currently in use (green curves along the graph)with blue color indicating the maximum CPU Frequency. Alongside it, there’s a Disk graph displaying the total current I/O in green and the highest active time percentage in blue. Similar findings related to the Network graph and Memory graph are also displayed. For Memory, the current Hard Faults per second can be seen in green and the percentage of physical memory in use in blue.

If you are interested in knowing more details about a particular tab, just select the associated tab.

2] CPU

Under the CPU tab, it is possible to filter each view of the given tabs by the process. Simply check the box for that process, and the bottom window will only show the activity for that process. With no processes selected, the bottom windows will transform into an activity page for all active processes. The numeric scale for the graphs on the right will change as activity changes. On the right side, you will see the usage graphs that will help you monitor the CPUs.

3] Memory tab

The memory tab shows the memory being consumed by each of the running processes, along with graphs on the right side. This gives us a quick view of what physical memory is being used for. One can easily view the total physical memory and what it is actively used, along with showing what is hardware-reserved. Hardware Reserved represents physical memory addresses that have been reserved by hardware and is not available for Windows to use.

4] Disk tab

Under the ‘Disk’ tab you will find those processes that are engaged in some Disk activity. At the time you may find some process engaged in a lot of Read-Write activity. Right-clicking on any process will give you the option to End the process, End the complete process tree, etc.

5] Network tab

Under the Network tab, you can find which programs are accessing the network and which IP address it is connected to. This helps in narrowing down the problem if you find unusually high network activity.

Thus, the Resource Monitor offers many advantages over previous individual tools like System Monitor, Performance Logs and Alerts, and Server Performance Advisor in a way that it combines the functionality of those tools into a single interface. Besides, it provides a much more in-depth view of system activity and resource usage than previous tools like Task Manager.

TIP: See this post if the Resource Monitor is not working.
