Know of any Java garbage collection log analysis tools? [closed]

Answer 1

I tried a online tool http://gceasy.io , it can read my sun jdk 1.8 gc log.

Answer 2

I use YourKit java profiler, which lets you measure this sort of thing, and much more, but using it's own format rather than analysing the log. It can do more under Java 5, but should work under 1.4.

Answer 3

A few years ago, John Coomes (Hotspot GC group) had released PrintGCStats, an awk script to "summarize statistics about garbage collection, in particular gc pause time totals, averages, maximum and standard deviations.". A copy of the script is hosted on java.net : http://java.net/projects/printgcstats

Answer 4

gchisto plugin for VisualVM doesn't work https://gchisto.dev.java.net/

I have a file with all details of printgc for jdk1.6 but couldn't find a tool to read that. Previously with jdk1.5 we used HPjmeter it worked fine, but now with jdk1.6 it doesn't

Tried following: IBM Pattern Modeling and Analysis Tool for Java Garbage Collector -- it doesn't recognizes the file. GCCollector doesn't work, it keep on reading file for analysis.

Answer 5

jconsole can help you a lot, but I think it's Java 5 and later only. Once I heard someone of SUN speaking at our university and he said that Java 6's garbage collector is A LOT better than the old ones which needed complicated tuning nearly all the time for big applications. Java 6 GC seems to scale a lot better on SMPs.

Answer 6

How about trying out some profiling tool like JProbe Freeware (Eclipse plug-in).
