A trace that traverses multiple locations is divided into subtraces. Hence, a subtrace is identified by the Location tuple (Host (e.g. IP), Container(e.g. JVM Id), Application Id, Business Transaction Id). Subtraces are structured along a composite pattern (tree structure). In this way, subtraces provide a coarse-frained grained view on the logical trace. A subtrace, in turn, contains a tree of Callables, hence, a trace covering one Location.
