Performance Metrics for Windows Server Monitoring
Measure critical performance metrics of your Windows servers including CPU, memory, disk utilization, services, processes and network traffic from a unified dashboard. Once the Windows agent is successfully installed, log in to the Site24x7 web client and navigate to Server > Server Monitor > Servers > click on the newly added monitor to view the performance metrics.
The Windows agent sends data to the Site24x7 data center using WMI queries. As the agent has to be downloaded and installed in your servers, learn more on how secure the agent is.

Summary
Get visibility of all the important parameters of your Windows server performance in a single console. The heat map analysis gives you a quick summary on the status and performance of your server over the last seven days. You can view data for different time periods by choosing the appropriate time frame from the drop-down at the top right corner of the page. You can also export the performance details as CSV/PDF or send via email.
Click the icon 
to view the Performance Reports for metrics including CPU, memory, disk utilization, and more.
Regular monitoring of CPU usage is critical to analyzing the CPU load over a stipulated period and overcoming performance regressions.
However, not all high CPU usage is critical. Site24x7's feature that allows you view customized reports based on the period proves useful in identifying the CPU usage that is really problematic. This helps you drill down to the actual reason for a CPU spike. Based on the analysis, you can come up with solutions, like upgrading the CPU hardware, adding more CPUs, or shutting down frivolous services that are hogging these critical resources.
The Performance Report (click on ) for CPU utilization lists the following metrics:
- CPU utilization by cores
- Interrupts: The average number of hardware interrupts that the processor is receiving
- Context switches: The rate of switches from one thread to another—thread switches can occur either inside a single process or across processes
- Average CPU usage (%) per minute
Also, view the top five processes consuming CPUat a particular point in time by hovering over a point on the CPU Utilization graph.
The CPU utilization data is obtained from:
- PercentProcessorTime counter of Win32_PerfRawData_Counters_ProcessorInformation WMI class - For Windows Server 2008 R2 and above
- PercentProcessor Time counter of Win32_PerfRawData_PerfOS_Processor WMI class - For versions before Windows Server 2008 R2
The CPU Utility % data is obtained from the PercentProcessorTime counter of Win32_PerfRawData_Counters_ProcessorInformation WMI class (for Windows Server 2012 and above). This metric is not supported for OS versions below Windows Server 2012.
Monitoring memory usage helps you to identify underused servers and redistribute loads efffectively. This helps to detect server overloads before they cause a downtime or data loss. Know how the memory utilization is calculated for Windows servers.
The performance report (click on ) for memory utilization lists the following metrics:
- Swap memory utilization
- Memory used
- Memory break up of free physical memory and free swap memory
- Memory pages in - Number of pages read from disk to resolve hard page faults
- Memory pages out - Number of pages written to disk to free up space in physical memory
- Memory page faults - A page fault occurs when a process requires code or data that is not in its working set (its space in physical memory). Know how this metric is calculated.
- Average memory usage (%) per minute
Also, view the top five processes consuming memory for a particular point of time by hovering on a particular point in the Memory Utilization graph. The top process data is calculated using the WMI query 'Win32_PerfFormattedData_PerfProc_Process'.
Get a split up of the free physical memory and free swap memory available in your Windows server. The less used files can be moved to the swap space until they are needed and new files can be swapped to the RAM. This helps to better plan and allocate resources to avoid server overload and data loss. Know how the memory utilization is calculated for Windows servers.
The system/processor queue length is the number of threads each processor is servicing. Continuous monitoring of the processor queue length can help indicate if there are more threads than the current processor can handle in an optimal way.
Get an idea of what your disk usage will be after seven days, based on your current disk usage. If the disk usage and predicted value are irregular or show a sudden spike, then it means there is some performance degradation issue in the usage and definitive action is required. Go to the Disks tab and check for the disk utilization of each partition and resolve the issue before it affects the overall performance of your server.
Know the latest events in your server, categorized as Warning, Error, and Information etc. The data is refreshed after every poll and this helps in getting to know any abnormal increase in the number of error/warning events and take immediate action.
View a list of top processes based on the CPU or memory usage in your server. Use the toggle button to choose between CPU and memory usage.
The applications like IIS, SQL, Exchange, SharePoint, Active Directory will be listed (if they are running in your server) along with their respective monitor display names. Click on the monitor name to go to the respective application monitor's Summary page.
The complete history of your server's DOWN and TROUBLE status is listed with the duration of the DOWN/TROUBLE period, reason for the outage, and the root cause analysis (RCA) details.
