Is there memory usage profiler available?

For time profiler for XYZ, I can just run 'time XYZ', or if I have the source code in C/C++, I even can use gprof to get profiled results.

Is there any similar tool for memory usage?

• Is there any tool I can use something like 'memory XYZ', to get info such as min/max/median memory usage?
• What tool do you use for memory profile with C++/Objective C/C#/Java?
• I thought about running top periodically to parse the results, is there any tool does something similar?

I mainly use Mac OS X, but Linux and Windows7 for regular basis, so cross platform wo开发者_运维知识库uld be better.

For Windows, there is Rational Purify from IBM. Valgrind for Linux or Mac.

For Java you can use the Eclipse TPTP project, or the fabulous YourKit compiler.

for what platform? for linux there is http://valgrind.org/ (works for any native binary) for java .net or mono there are framework specific memory profilers
