Demux the application log into per-client or per-request sets of messages
When multiple clients concurrently access the application it’s hard to tell which log message belongs to which client because log messages don’t contain the java thread name. How is this problem usually solved?
I’m not aware of any method to influence the logformatting in Mendix. I think your best bet is to try instrumentation approach like datadog, newrelic, dynatrace, etc Or perhaps tracer like zipkin (https://zipkin.io/pages/tracers_instrumentation)
