Issue/Introduction

Our logs were getting filled with these entries:

8/18/23 11:51:30 AM PDT [WARN] [IntroscopeAgent.TransactionSamplingStrategy] Either Intelligent Instrumentation or Deep Tracing are disabled, however one of selected sampling strategy requires them. Trace is discar
ded

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:

8/18/23 12:01:57 PM PDT [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 didn't work.... 

Any ideas?
