I'm using GCMV within ISA 4.1 to analyze some gc logs from a cluster. When I open a native_stderr.log file in that tool, it always creates the following 4 reports/tabs:

  • Table data
  • Line plot
  • Structured Data
  • native_stderr.log

These reports are useful, but they don't summarize much and only one of them (Line Plot) can actually be filtered based on date and time.

What is really useful is when the tool also generates a summary report with recommendations and a filterable table of high-level stats. However, for whatever reason the GCMV tool doesn't always generate this report. It usually seems to be created for 20% of the files that I analyze, and it's not even consistently generated for the same file twice.

Is there some way that I can force GCMV to create the summary report every time?

I actually asked someone at IBM about this and was told two things:

  • ISA 4.x really isn't officially supported any more, so I'm going to have trouble getting any help.
  • Most of the experts at IBM use PMAT (IBM Pattern Modeling and Analysis Tool for Java Garbage Collector) anyways, so why don't I try that?

I did and am VERY happy with it. It's very lightweight and fast and gives me MUCH more information than I was getting with GCMV. And the best part is that it is a standalone tool that does not require ISA, so I don't have to go through the hassle of installing ISA 5.x.
