partial log file analysis about gcviewer

[eostermueller]

+1 for this feature. I regularly use this in IBM's pmat, whose support for Oracle JVM's is lacking.
Need this to compare GC results of two load tests with the same duration.

This is also helpful to factor out "warm up" tests that show up in the same log file.
btw, thanks for gcviewer. I've only been using it for a day and I love it.

Just check did anyone work on this item? Recently I found we really want this feature, beside to show the chart, also need the provide the summary of those "partial log".

First time to look at the code, Initial thought.

• Add method in GCModel.java, with start and end time as parameters;
• In that method ,iterate the allEvents list, extract the event list within the time range;
• Then create a new GCModel instance with the event list just get.

Hi,

I wouldn't know of anybody working on this feature, so you are very
welcome to start work here.

Your initial thoughts sound good. You'll need to use GCModel#add() to
add the cropped allEvents list, because all calculations are made there.
If add() is not used, no metrics will be available.

Best regards,
