Several built-in agent policies are provided with the App Visibility agent for Java:

  • Light
    Records the least amount of information and has a low performance hit on the recorded application.
  • Medium
    Records more information than the Light policy, and has a higher performance hit on the recorded application. This is the out-of-the-box default policy.
  • Deep
    Records extensive details of transactions and has a severe performance hit on the recorded application. Use this policy sparingly.
  • Standalone
    Use the Standalone policy when App Visibility is not integrated with Real End User Experience Monitoring Software Edition. The settings are the same as the Light policy, except for any settings related to the integration.
  • Max
    The Max policy fully activates all recording parameters, for use in small proof-of-concept environments. The Max policy has the following characteristics:
    • Overrides global and custom threshold settings to maximize the number of "interesting" transactions that are considered for capture.
    • Records all types of technologies
    • Uses a very short heartbeat interval so that agents are updated quickly

Choosing the right policy

  • Use the Standalone policy if App Visibility is not integrated with BMC Real End User Experience Monitoring Software Edition.
  • Use a Light, Medium (default), or Deep policy by evaluating the configuration settings in the following table.

The table includes a selection of significant properties in the agent policies.

Properties that are commented out (that is, begin with a # character) have a default value that is usually mentioned in the property's comment.
