This repository acts as an umbrella project for different subprojects that can be combined to create BDWatchdog, a monitoring and profiling framework capable of producing resource usage information on a process-level as well as detailed profiling of Java-based applications in the form of flame graphs. In addition, auxiliar tools have been developed such as a web application to visualize the data generated and a timestamp generator used to bound experimentation runs.

Thanks to the process-based monitoring approach, this framework can be deployed on newer virtualization technologies like containers, acting as a base for other projects that may need real-time container resource monitorization.

• If you need more information regarding the process-level monitoring check out the MetricsFeeder subproject.

• If you want to know more about real-time java profiling with flame graphs, check out the FlamegraphsGenerator subproject.

• If you want to know how many of the plots presented on this umbrella project have been generated, you can check out the TimeseriesViewer subproject, which hosts a web application to visualize the time series data generated by the MetricsFeeder subproject and the flame graphs created from the data of the FlamegraphsGenerator subproject, as well as other utilities such as integration with the timestamping service.

• If you want to know more about the timestamp generation used to delimit the time duration of experiments and tests, visit the TimestampsSnitch subproject.

BDWatchdog has been developed in the Computer Architecture Group at the University of A Coruña by Jonatan Enes ([email protected]), Roberto R. Expósito and Juan Touriño.
