The Common Trace API (CTA) is an interface-based specification of a common trace representation to allow a monitoring-tool-format-independent access of trace data. The CTA supports the exchange of monitoring data between stakeholders (e.g., Ops and Dev, or different research groups) while the consumer accesses the data with the CTA.

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.
