Issue/Introduction

 Java Agent produces huge autoprobe log files, ranging into gigabytes in size.

Cause

Huge Autoprobe logs can be caused by dynamic instrumentation being triggering excessively, resulting in frequent re-instrumentation. (This also means quick growth of the autoprobe.log files which records the re-instrumentation.)

Environment

Java Agent, 9.7 and above.

Resolution

Simply disabling the autoprobe.log is not recommended, as the underlying re-instrumentation will continue. Instead for cases where this occurs, the following should be changed in the agent profile (IntroscopeAgent.profile):

 

introscope.autoprobe.dynamicinstrument.enabled=false

introscope.autoprobe.deepinheritance.enabled=false

introscope.agent.deep.entrypoint.enabled=false

 

 The application should be restarted for these changes to take effect.
