Issue/Introduction

Our logs were getting filled with these entries:

[WARN] [IntroscopeAgent.TransactionSamplingStrategy] Either Intelligent Instrumentation or Deep Tracing are disabled. However, one of selected sampling strategy requires them. Trace is discarded

Adding this removed them:

log4j.additivity.IntroscopeAgent.TransactionSamplingStrategy=false
log4j.logger.IntroscopeAgent.TransactionSamplingStrategy=ERROR, logfile

After a recent release we began seeing these messages again but in a somewhat different format:

[WARN] [I.TransactionSamplingStrategy] Either Intelligent Instrumentation or Deep Tracing are disabled, however one of selected sampling strategy requires them. Trace is discarded

I tried following a similar patter and added this to the profile:

log4j.additivity.I.TransactionSamplingStrategy=false
log4j.logger.I.TransactionSamplingStrategy=ERROR, logfile

but it did not resolve the issue.

Environment

Release : SAAS

Resolution

Agent: Java

Agent Version: 2023.7.1.14

Please use the following since the agent switched from log4j to log for vulnerability.

introscope.agent.log.level.IntroscopeAgent.TransactionSamplingStrategy=ERROR
