Instead, customers will get the following log message: ``` INFO -- ddtrace: [ddtrace] (/app/lib/ddtrace/profiling/tasks/setup.rb :44:in `activate_cpu_extensions') CPU time profiling skipped because native CPU time is not supported: The `logging` gem is installed and its thread inherit context feature is enabled. Please add LOGGING_INHERIT_CONTEXT=false to your application's environment variables to disable the conflicting `logging` gem feature. See TwP/logging#230 for details. Profiles containing Wall time will still be reported. ``` This is a repeat of #1362 -- the logging gem also monkey patches `Thread` initialization using `alias_method`, which is incompatible with our instrumentation that uses `preload`. For details, see TwP/logging#230 where we submitted a fix to the upstream gem. Right now the only way to avoid this issue and still enable proflier is to either remove the logging gem or to disable the feature using the `LOGGING_INHERIT_CONTEXT` environment variable. If/when the gem creators accept our proposed change and release it, we'll need to revise this to take that into consideration, as we do for rollbar. NOTE: I'm not entirely happy with the complexity that is accumulating for the tests, but I've decided to not refactor it yet. If we need to add more gems, we should definitely refactor the tests. My hope is that soon we can get rid of our `Thread` monkey patches, and thus get rid of all of this instead.
