Extending Java Performance Monitoring Framework with Support for Linux Performance Data Sources
Júnoš, Peter ; Bulej, Lubomír (advisor) ; Babka, Vlastimil (referee)
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. Keywords: performance measurement, JPMF, Linux, netlink stats, procfs stats 1

Flexible Event Processing Subsystem for the Java Performance Monitoring Framework
Júnoš, Peter ; Bulej, Lubomír (advisor) ; Hnětynka, Petr (referee)
Java Performance Measurement Framework (JPMF) is a framework dedicated to description of points, where the performance is measured. This description is used to gather performance data in these running points. Data are gathered and written without any processing. The handling increases bandwidth and puts high load on the storage. JPMF does not provide any possibility for user to reduce this data. This thesis aims to solve the described problem by introduction of filtering and aggregation, that should reduce the bandwidth. Additionally, performance bottlenecks in various parts of JPMF are investigated and removed. Powered by TCPDF (www.tcpdf.org)
