Extending Java Performance Monitoring Framework with Support for Linux Performance Data Sources

Title: Extending Java Performance Monitoring Framework with Support for Linux Performance Data Sources Author: Peter Júnoš Department: Department of Distributed and Dependable Systems Supervisor: Ing. Lubomír Bulej, Ph.D Abstract: Java Perfomance Measurement Framework (JPMF) is a library, that is able to hook into program and gain performance information in given watchpoints. Notable drawback of currect implementation are missing sen- sors, that would be able to measure performance statistics related to stor- age, CPU, memory and network interfaces under Linux. Linux does not provide unified way of accessing such performance statis- tics. They can be accessed using virtual file systems, syscalls and netlink interface. The goal of this work is extending JPMF, so that it will provide measurement of mentioned performance statistics in a Linux-specific way.
