Jamf Pro Web App Memory

Jamf Pro allows you to view the amount of memory being used by the web app. If you need to change the amount of memory allocated to the web app, you can use Jamf Pro Server Tools.

Note:

To improve the user experience, or if your Tomcat server is experiencing problems with instability, you may want to increase the memory allocated to Tomcat. Depending on your environment and Jamf Pro configuration (such as the number of managed devices, check-in frequency, or actions performed by the server), you may need to increase the amount of memory assigned to Tomcat. Each environment is different. Consult your system administrator for monitoring and scaling your environment.

If you decide to allocate more memory to Tomcat, ensure that enough memory remains available for the operating system to perform normally. If other services, such as MySQL, are running on the same hardware as Tomcat, ensure enough memory is available to operate all running services, or consider moving those services to a separate dedicated server.

Viewing Memory Usage

  1. In Jamf Pro, click Settings in the top-right corner of the page.
  2. Click Jamf Pro Information.
  3. Click Usage.

    Current free and used memory values are displayed.

Configuring Web App Memory Using Jamf Pro Server Tools

    C:\Program Files\JSS\bin\server-tools-gui.jar

  2. Select Tomcat Settings.
  3. Enter values in the Tomcat minimum memory and Tomcat maximum memory fields to configure the amount of memory allocated to the web app.
    Note:

    Type an "m" after the memory value to specify megabytes, e.g., "256m".

  4. Restart Tomcat. The changes will take effect after Tomcat restarts.

Configuring Web App Memory Using the Tomcat Monitor Application
