VDM Verlag Efficiency of LTTng as a Kernel and Userspace Tracer on Multicore: Performance Analysis of LTTng Kernel and Userspace tracer in a Multicore Environment

With the advent of huge multicore processors, complex hardware, intermingled networks and huge disk storage capabilities the programs that are used in the system and the code which is written to control them are increasingly getting large and often much complicated. There is increase in need of a framework which tracks issues, debugs the program, helps to analyze the reason behind degradation of system and program performance. Another big concern for deploying such a framework in complex systems is to the footprint of the framework upon the setup. LTTng project aims to provide such an effective tracing and debugging toolset for Linux systems. Our work is to measure the effectiveness of LTTng in a Multicore Environment and evaluate its affect on the system and program performance. We incorporate Control and Data Flow analysis of the system and the binaries of LTTng to reach for a conclusion.
