Each ActorSystem can implement exactly one of these to control the decision-making around which traces to include and which ones to exclude.
When this type is configured, it will replace all of the IFilterRules that have been previously defined.
public interface ITraceFilter
Evaluates a message processed by an actor and determines whether or not to include it in the current or a new trace.
bool ShouldTraceMessage(object message, bool alreadyInTrace)
The message currently being processed by an actor.
Whether or not this message is already part of an active trace.
true unless you are explicitly trying to filter a given message out of your trace.
