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. **Important**   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. ## Related topics [How to Manage Virtual Applications by Using the Command Line](how-to-manage-virtual-applications-by-using-the-command-line.md)
