Massif Visualizer - Ready for Testers and Feedback! (March 29, 2010)
memory consumption overview
Hello everyone!
In my opinion, the massif visualizer is ready for testing. I bet there are still a few rough edges, but the most important features are in. So if you are going to do any memory profiling these days, please take a look at my tool and give me feedback. I’d be especially interested in whether the massif visualizer helps in the work flow to analyze massif data files.
My personal work flow so far is the following:
callgraph of detailed massif snapshot
- generate massif log, one way or the other (unit tests preferred since they give you reproducible test cases)
- open log in massif-visualizer, look at overall consumption chart 1. how does the memory consumption evolve? is there a memleak? 2. are there designated peaks which could be reduced? 3. are there any (significant) contributions to the memory consumption, that needlessly stay over the whole application life?
- to find the actual culprits in code and/or to grasp the composition of a memory peak, use the detailed snapshot analysis
