gatling.conf can’t do anything about logging, logback.xml can.
What’s the difference between editing gatling.conf instead of editing logback.xml?
Then, you know you can use System properties in your logback.xml, right?
The link you sent says it requires Scala 2.11. Gatling ships with Scala 2.10. But that’ can’t be the problem, because…
I looked at the source code of Gatling, e.g. gatling-core/src/main/scala/io/gatling/core/session/Session.scala,
it imports com.typesafe.scalalogging.StrictLogging, and then just extends StrictLogging, exactly like the website you linked to,
but when I do that, I get a compile error:
09:37:24.697 [ERROR] i.g.a.ZincCompiler$ - /src/poc/rtde/src/scala/com/cigna/common/SessionManagement.scala:4: object StrictLogging is not a member of package com.typesafe.scalalogging
