CPU usage, including real-time usage, average CPU consumption, and total CPU usage

Resource Monitor is a Windows utility that provides more information than Task Manager without getting into confusing details. It offers insights into CPU usage, memory usage, disk usage, and network usage. The CPU tab in Resource Monitor provides detailed information about CPU utilisation, including real-time usage, average CPU consumption, and total CPU usage.

The CPU tab in Resource Monitor has four panes of information and several graphs. The Processes pane displays a list of processes running on the system, along with their respective CPU usage. This pane allows users to sort the processes by different columns, such as CPU usage, memory usage, or other criteria. It helps identify which processes are utilising the most CPU resources and enables users to focus on specific processes for further analysis.

The Services pane in the CPU tab examines the various Windows "services" and their CPU usage. These services are support functionalities provided by background processes in Windows. By selecting a particular service, users can explore its individual CPU consumption. This level of detail is often challenging to obtain with other tools, as many services are bundled into the same program, and those tools only provide aggregate information at the program level.

The Associated Handles pane provides insights into the resources utilised by the selected process in the Process list. It shows which open files and other resources are being used by each process, contributing to a comprehensive understanding of CPU usage. Additionally, the CPU tab includes graphs that visualise CPU usage per core, Service CPU usage, and total CPU usage. These graphs offer a quick overview of CPU utilisation, complementing the detailed information presented in the panes.

Memory usage, including RAM use, physical memory, and memory management

The Resource Monitor is a utility available on Windows that provides information about what's happening on your system. It is organised into four areas: CPU, Memory, Disk, and Network usage. The Memory tab in the Resource Monitor allows you to track memory usage, including RAM use, physical memory, and memory management.

The Memory tab has two panes: the upper pane, which displays the processes with memory activity, and the lower pane, Memory, which shows the amount of RAM being used by each process. The lower pane is sorted by the Private column, which measures the amount of physical memory (in kilobytes) currently being used by a specific process and not shared with other processes. This provides an accurate indication of the amount of memory required by an application to run.

The Memory tab also allows you to monitor hard faults, which are indicated in orange in the Hard Faults/Sec graph. While monitoring hard faults is not the only or best way to monitor memory use, it provides a good starting point. The Physical Memory table presents a global view of memory usage, with a bar graph that offers a unique perspective on memory usage. Each section of the bar graph represents a list of pages of memory.

Additionally, the Resource Monitor provides insights into Windows 10's memory management. The OS creates a virtual memory system consisting of available physical memory and a page file system on the hard disk. This virtual memory system enables the OS to allocate fixed-length blocks of memory, ensuring contiguous addressing in both physical and virtual memory. As applications are loaded and files are accessed, the OS's memory manager monitors the working set of each process and balances the demand for memory from various sources.

The Resource Monitor is a valuable tool for system administrators and users seeking detailed insights into memory usage and management on their Windows PCs.

Disk usage, including disk activity, file-level breakdown, and overall disk activity

Disk usage is one of the four areas that the Windows utility, Resource Monitor, provides information about. It offers more information than Task Manager and gives tools to dig deeper into the activity on a Windows machine. It can be launched from the advanced tools tab in "Performance Information and Tools", which is located in the Control Panel. It can also be launched directly by running Resmon.exe.

The Disk tab in Resource Monitor provides information on disk usage, including "Processes with Disk Activity", "Disk Activity", and "Storage". The top pane, Processes with Disk Activity, lists the processes currently accessing the disk and how much data is being read and written. The second pane, Disk Activity, breaks down disk activity to the file level, showing which process accesses which file and the type of read or write activity. The Storage pane presents information on disk activity at the drive level. The graphs to the right include an overall disk activity meter and show how much work is waiting to be handled for each disk in the system.

The Disk tab can be used to troubleshoot Windows performance issues. For example, if you are experiencing slow performance or response on the server, it could be due to a high disk queue. By identifying the responsible processes, you can analyse them to determine the root cause of the high disk queue.

The Network tab is also related to disk usage as it shows the networking activity of the processes running on your machine. The upper pane, Processes with Network Activity, displays the processes accessing the network and the amount of data transmitted. The network tab also shows the IP address that the process is connected to.
