1. A method comprising: receiving a request for a first trace data having a first trace format and associated with a first programming engine that is associated with first trace activities at a first computer system, and a second trace data having a second trace format and associated with a second programming engine that is associated with second trace activities at a second computer system, the first trace format being compatible with a common trace data format, wherein the second trace format is incompatible with and independent of the first trace format and the common trace data format, and wherein the first programming engine is incompatible with and independent of the second programming engine, wherein the common trace data format comprises a trace format that is designated as the common trace data format, the trace format including a common performance trace (CPT) format, wherein the (CPT) format includes a common interface model (CIM)-compliant format and provides the common trace data format defining a type of data that is needed to analyze performance; analyzing the second trace data format of the second trace data for conversion to the common trace data format by determining compatibility or incompatibility of the second trace data with the common trace data format, wherein determining is performed based on correlators provided by a trace service, wherein the correlators include a first correlator containing engine information relating to the second programming engine, and a second correlator serving as a main correlator to group up trace records belonging to one or more traces; converting the second trace format of the second trace data such that the second trace format is compatible with the common trace data format, wherein converting includes updating the trace service by replacing common trace data format-incompatible trace functionalities of the trace service with common trace data format-compatible trace functionalities; integrating the first trace data having the first trace format with the second trace data having the converted second trace format; and providing access to the integrated first and second trace data.
