  4. In the right-hand pane, click on the green plus icon to add a new counter.
  5. Under "Available counters", expand "Memory" and select the desired counters, such as "Committed Bytes" or "Page File Usage".
  6. Click on "Add" and then "OK" to add the counters to the monitor.
  7. Observe the counters in real-time or let the monitor run for a specific period to collect data.
Pros Cons
1. Provides advanced options for monitoring and analyzing virtual memory usage. 1. May require some technical knowledge to interpret the performance counters.
2. Allows customization of monitoring parameters and data collection intervals. 2. Requires additional setup and configuration compared to other methods.
3. Provides various visualization options, including charts and graphs. 3. May overwhelm novice users with too many performance counters and options.

Method 4. How to Check Virtual Memory via PowerShell

PowerShell is a command-line shell and scripting language that provides administrators with powerful automation and management capabilities. Here’s how you can check virtual memory via PowerShell:

  1. Open PowerShell as an administrator.
  2. Run the command Get-WmiObject Win32_ComputerSystem to retrieve general system information.
  3. Look for the properties TotalVirtualMemorySize, FreeVirtualMemory, and TotalVisibleMemorySize to obtain virtual memory-related details.
  4. Run the command Get-WmiObject Win32_PageFileSetting to retrieve information about the page file settings.
  5. Look for the properties AllocatedBaseSize and CurrentUsage to obtain page file-related details.
Pros Cons
1. Provides a command-line interface for quick and efficient checking of virtual memory. 1. Requires familiarity with PowerShell and command-line syntax.
2. Allows easy automation and scripting of virtual memory-related tasks. 2. Only provides static information and does not offer real-time monitoring.

5 FAQs about Checking Virtual Memory on Windows Server 2012 R2

Q1: Can I increase the virtual memory on my server?

A: Yes, you can increase the virtual memory on your server by adjusting the page file settings. However, increasing virtual memory may not always be the most efficient solution, and it is recommended to optimize your server’s physical memory first.

Q2: How much virtual memory is recommended for my server?

A: The recommended amount of virtual memory depends on various factors, such as the server’s workload, the number of running applications, and the available physical memory. As a general guideline, it is recommended to set the initial size of the page file to 1.5 times the amount of physical RAM, and the maximum size to 3 times the amount of physical RAM.

Q3: Can I check virtual memory usage remotely?

A: Yes, you can check virtual memory usage remotely by using tools like PowerShell remoting or remote desktop access to the server. Ensure that you have the necessary permissions and network access to the server.

Q4: How can I troubleshoot virtual memory-related issues?

A: If you encounter virtual memory-related issues, such as frequent out-of-memory errors or sluggish performance, you can try the following steps:

1. Monitor the virtual memory usage and page file settings using the methods described in this blog post.

2. Optimize your server’s physical memory by adding more RAM if necessary.

3. Adjust the page file size based on your server’s needs and workload.

4. Identify and resolve any memory leaks or excessive memory consumption by specific applications or processes.

Q5: Is it possible to disable the page file and rely only on physical memory?

A: While it is technically possible to disable the page file, it is generally not recommended. The page file serves as a safety net in case the physical memory is exhausted, allowing the system to continue functioning. Disabling the page file may lead to stability issues and potential crashes in situations where the physical memory is fully utilized.
