Autoprobe logs are growing to huge sizes.

Products

• CA Application Performance Management Agent (APM / Wily / Introscope)
• INTROSCOPE

Issue/Introduction

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

Environment

Java Agent, 9.7 and above.

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.)

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.
