How to Manage the App-V Client Cache Using Performance Counters

You can use the following procedure to determine how much free space is available in the Application Virtualization (App-V) client cache by using Performance Monitor to display the information graphically. This information is captured on the client computer by a performance counter called “App Virt Client Cache,” and it includes the following counters: “Cache size (MB),” “Cache free space (MB),” and “% free space.”

To determine client cache space usage

  1. Open a command prompt as administrator, or click Start, Run, type perfmon.exe, and click OK.

  2. Depending on the Windows operating system being used, click the Performance Monitor or System Monitor tool after the MMC window opens.

  3. To add counters, right-click the graph area and select Add Counters.

  4. Click the drop-down to display the list of available counters, scroll to find App Virt Client Cache, and then add the three counters.

    The App-V performance counters are implemented in a 32-bit DLL, so to see them, you must use the following command to start the 32-bit version of Performance Monitor: mmc /32 perfmon.msc. This command must be run directly on the computer being monitored and cannot be used to monitor a remote computer running a 64-bit operating system.
