![]() Figure B The Resource Meter’s display uses three gas gauge-like monitors to show you the amount of available system resources in each category.īecause resource management was horrible in the Windows 9x days, system crashes were inevitable. As you can see, this display used three gas gauge-like monitors to show you the amount of available system resources in each category. If you double-click the icon, you will see the Resource Meter dialog box, shown in Figure B. Figure A Hovering the mouse pointer over the Resource Meter icon produces a display of the currently available system resources in three categories. Once you have Resource Meter up and running, you can hover the mouse pointer over the icon and you will see a pop-up display that breaks down the amount of available system resources into its three categories: System, User, and GDI, as shown in Figure A. To help you to appreciate the memory usage information in Windows 7 and to put the evolution of Windows resource monitoring into perspective, I thought I would begin by taking a quick look back at Windows 9x’s Resource Meter. This blog post is also available in PDF format in a TechRepublic download. Note: Keep in mind that this is a Beta version and that the look and features of Windows 7 that I will discuss here may very well change between now and the time the operating system is actually released. In this issue of the Windows Vista and Windows 7 Report, I’ll take a closer look at the changes on Task Manager’s Performance tab and investigate the Physical Memory usage chart. I have also noticed a very nice chart in the new Resource Monitor that provides very detailed information on physical memory usage at a glance. ![]() With Windows 7, I’ve discovered some slight, but notable, changes in the way that memory usage is reported on the Performance tab of the Task Manager. Over the years Microsoft has vastly improved the primitive Resource Meter and increasingly made it easier to see what is going on with the operating system’s use of memory. Greg Shultz takes a closer look at the changes on Task Manager's Performance tab and investigates the Physical Memory usage chart.Įver since I discovered how to use the Windows 9x’s Resource Meter to keep track of system resources and prevent system crashes caused by depleting system resources when running more than one application at a time, I’ve made good use of Windows monitoring tools. With Windows 7, there are some slight, but notable, changes in the way that memory usage is reported on the Performance tab of the Task Manager. This monitor does not contain any external references.Take advantage of tools to monitor memory usage in Windows 7 If you observe a consistent and significant increase in any of these counters, it may be necessary to contact the application vendor for support. If the system appears to be leaking memory, the specific application can be identified by monitoring the following counters for each running process: If any one of these counters continually increase over time, it is possible that an application may be leaking memory. Open System Monitor and monitor the following system wide performance counters over time: To identify an application that is leaking memory, do the following: If the system has been adequately provisioned with physical memory and application load but it continually exceeds the available physical memory threshold over time, it is possible that an application is leaking memory. Move applications to one or more additional servers. To address a low physical memory condition an administrator may chose one or more of the following options:Ĭlose or stop one or more applications, services, processes.Īdd additional Physical Memory to the computer. ![]() Start Memory Available MBytes Performance View To view recent history for the Memory\% Available MBytes counter you can use the following view: Too many applications are running simultaneously on the computer.Īn application may be leaking memory over time. The amount of available physical memory can become low under the following circumstances: ![]() Overall system performance may significantly diminish which will result in poor operating system and application performance.Īvailable MBytes is the amount of physical memory that is available for use by applications and processes. The Available MBytes (Memory\% Available MBytes) for the system has exceeded the threshold. How frequently (in seconds) the value should be sampled.
