Windows Server 2012 introduced several enhancements aimed at improving system performance and resource management. One of the most valuable tools included in this operating system is the Resource Monitor. This utility provides real-time data about the system’s resource usage, allowing administrators to monitor CPU, memory, disk, and network activity effectively. Understanding how to utilize the Resource Monitor can significantly enhance the management of server resources, leading to improved performance and stability.
What is Resource Monitor?
Resource Monitor is a system monitoring tool that provides detailed information about the usage of hardware resources by various processes and services running on a Windows Server. It allows administrators to identify resource bottlenecks, troubleshoot performance issues, and optimize system performance. The Resource Monitor can be accessed through the Task Manager or directly via the Run dialog.
Accessing Resource Monitor
To access Resource Monitor in Windows Server 2012, follow these steps:
- Press
Ctrl + Shift + Escto open Task Manager. - Click on the Performance tab.
- At the bottom of the window, click on Open Resource Monitor.
Alternatively, you can open the Run dialog by pressing Windows + R, typing resmon, and hitting Enter.
Understanding Resource Monitor’s Interface
The Resource Monitor interface is divided into several tabs, each focusing on different resource types:
- CPU: Displays the current CPU usage, including processes using the most CPU resources, services, and associated handles.
- Memory: Shows memory usage details, including the amount of physical memory in use, available memory, and the processes consuming the most memory.
- Disk: Provides information about disk activity, including read and write speeds, and the processes accessing the disk.
- Network: Displays network activity, including data sent and received, and the processes using network resources.
Using Resource Monitor for Performance Monitoring
Resource Monitor is particularly useful for diagnosing performance issues. Here are some practical applications:
Identifying High CPU Usage
If a server is running slowly, the CPU tab can help identify processes that are consuming excessive CPU resources. For example, if a specific application is consistently at the top of the list, it may need optimization or replacement.
Memory Management
In the Memory tab, administrators can see which processes are using the most memory. If the system is running low on memory, it may be necessary to close certain applications or increase the server’s RAM.
Disk Activity Monitoring
The Disk tab allows for monitoring of read and write operations. If a server is experiencing slow disk performance, this tab can help identify which processes are causing the bottleneck.
Network Traffic Analysis
The Network tab provides insights into network usage. If users are experiencing slow connectivity, this tab can help identify if a particular application is consuming excessive bandwidth.
Conclusion
Resource Monitor is an essential tool for administrators managing Windows Server 2012. By providing real-time insights into CPU, memory, disk, and network usage, it enables effective troubleshooting and optimization of server performance. Understanding how to leverage this tool can lead to more efficient resource management and improved server reliability.

Resource Monitor is a great tool to identify which program/service is using resources like program, applications, network connection and memory usages.
To open Resource Monitor, go to Server Manage → Tools.
Click on “Resource Monitor”, the First Section is “Overview”. It tells how much CPU is consuming every application and on the right side of the table, it monitors in real time the chart of CPU usage. The Memory tells how much memory every application is consuming and in the right side of the table it is being monitored in real time in the chart of CPU usage.
The Disk tab splits it by the different hard drives. This will show the current Disk I/O and will show the disk usage per process. The network tab will show the processes and their network bytes sent and received. It will also show the current TCP connections and what ports are currently listening, IDs too.

Performance is a basis for measuring
how fast application and system tasks are completed on a computer, and
reliability is a basis for measuring system operation. How reliable a
system is will be based on whether it regularly operates at the level
at which it was designed to perform. Based on these descriptions, it
should be easy to recognize that performance and reliability monitoring
are crucial aspects in the overall availability and health of a Windows
Server 2012 infrastructure. To ensure maximum uptime, a
well-thought-through process needs to be put in place to monitor,
identify, diagnose, and analyze system performance. This process should
invariably provide a means for quickly comparing system performances at
varying instances in time and detecting and potentially preventing a
catastrophic incident before it causes system downtime.
Performance Monitor, which is an MMC snap-in,
provides a number of tools for administrators that enable them to
conduct real-time system monitoring, examine system resources, collect
performance data, and create performance reports from a single console.
This tool is literally a combination of three legacy Windows Server
monitoring tools: System Monitor, Performance Monitor, and Server
Performance Advisor. However, new features and functionalities have
been introduced to shake things up, including data collector sets,
Resource view, scheduling, diagnostic reporting, and wizards and
templates for creating logs. To launch the Performance Monitor MMC
snap-in tool, select Server Manager or type perfmon.msc at a command prompt.
The Performance Monitor MMC snap-in consists the following elements:
• Overview screen
• Performance Monitor
• Data collector sets
• Report generation
The upcoming sections further explore these major elements of the Performance Monitoring tool.
1. Performance Monitor Overview
The first area of interest in the Performance
Monitor snap-in is the Overview of Performance Monitor screen, also
known as the Performance icon. It is displayed as the home page in the
central details pane when the Performance Monitor tool is invoked.
The Overview of Performance Monitor screen
presents holistic, real-time graphical illustrations of a Windows
Server 2012 system’s CPU usage, disk usage, network usage, and memory
usage, as displayed in Figure 1.
Figure 1. Viewing the Overview of Performance Monitor screen.
Additional process-level details can be
viewed to better understand your system’s current resource usage by
reviewing subsections beneath each metric being displayed. For example,
the Memory section includes % Committed Bytes in Use, Available Mbytes,
and Cache Faults/sec.
The Overview of Performance Monitor
screen is the first level of defense when there is a need to get a
quick overview of a system’s resources. If quick diagnosis of an issue
cannot be achieved, an administrator should leverage the additional
tools within Performance Monitor. These are covered in the upcoming
sections.
