To monitor GC activity in the IBM runtime for Java, use Health Center or enable the verbose gc log and analyze it with GCMV.
Health Center is a tool that can do live monitoring of the JVM including gc activity, threads, configuration, profiling and so on. Alternatively you can write Health Center data to a file and analyze it later.
To get even more detail that Health Center provides, you can turn on verbose GC logging with -Xverbose:gc, then a log of all gc activity is printed to stderr. You can write it to a log file with -Xverbosegclog:.
To analyze and graph the information in the verbose gc log, you can use the GCMV (Garbage Collection and Memory Visualizer) tool.
Health Center and GCMV are both available from:
