A unifying approach to performance analysis in the Java environment

In general, performance analysis tools deal with large volumes of highly co mplex data of varying types and at varying levels of granularity. The resul t is that if is common for there to be many different tools and components that implement performance data collection, recording, and reporting in an analysis environment. This variety complicates communication within a group and makes cross-group communication about specific performance findings ev en more difficult. The analysis of the performance of Java(TM) virtual mach ines and Java applications introduces additional complexity. We describe an approach that unifies the recording and reporting components of performanc e analysis into a single data model and standard set of reports. We have em ployed this model with significant success in the analysis of IBM's Develop er Kits for the Java virtual machine.
