IBM Support Assistant Garbage Collection and Memory Visualizer tool

GCMV provides analysis and views of your applications verbose gc output. GCMV uses a powerful statistical analysis engine which provides tuning recommendations in these areas: - Memory Leak Detection Detect Java heap exhaustion and memory leaks Detect "native" (malloc) heap exhaustion and memory leaks - Optimizing garbage collection performance Analyze output from different gc modes (optthruput, optavgpause, gencon, balanced ) Compare output from multiple logs -- side by side Determine gc overhead, detect long or frequent gc cycles and causes Recommend settings to avoid long or frequent gc cycles Recommend optimum gc policy - Fine tuning of Java heap size Determine peak and average memory usage Recommend Java heap settings Flexible user interface makes it possible to carry out further analysis of the data and to "drill down" into the causes of trends and export of data into .csv or jpeg Oracle Java Mission Control (JMC) is free for development use only. JMC does provide data visualization, but it does not make tuning recommendations, nor does it compare various run results side by side. This is a major usability issue.
