I have some applications running with java 1.4.2, and use all kinds of fashionable garbage collection monitoring options there. But now I have this other application that really needs jdk 1.3.1, and all I can find is verbose:gc. It shows how much time the garbage collection takes and how much garbage gets collected, but it does not even give me a timestamp. There must be more! Anyone?
Thanx Ernest. BillyBob, I sometimes see full GCs that take 7 seconds. This is harming my response times (which need to be below 2 seconds). I want to see how often that occurs. I also want to know the percentage of time my system spends garbage collecting. Maybe some tuning is necessary, increase memory or change how it is divided between young space, eden etc, another kind of garbage collection.
