Defrag Tools: #7 - VMMap

The Discussion

  Hey Andrew, Where did you get that great t-shirt ?

  @Roger: They all come from the Microsoft Company Store (the shop on Redmond campus, as opposed to the retail shops we now have). You'll have to come visit campus!

  Excellent presentation, I was using the vmmap earlier today to troubleshoot a memory leak issue and was overwhelmed with the stats. This makes it clear. Thank you!

  Hi,
  
  I understand the Heap Allocations button should allow me to see call stacks, but the button is always disabled (grayed out) no matter what I try. (I used the "Launch and Trace New Process" feature to run my application, but it doesn't help.)
  
  Thanks

  Hi
  
  I want to know the whole system physical and virtual memory map with system.
  how can i know that, as vmmap only tell about particular process.
  As in linux there is /proc/kallsyms. so for windows is there anything similar.

  Hi,
  
  Gr8 information here!
  While analyzing my application using Vmmap, I could see Heap of size 16192KB. However only part of it is committed and rest is reserved.
  Do you know why such a big chunk (16192KB) of Heap is allocated? and who allocates it? (Because my application does not allocate such huge heapmemory).
  
  THanks.

  Very interesting. Is VMMap information valid for Virtual Machines? In other words, if I put the VMMap executable on an Azure VM where my code is running on Windows Server 2012 R2, will I get information about the processes on that VM?
  
  Thanks,
  Jack

  @Jack: Virtualization doesn't affect the Virtual Memory layout of processes (if it did, that'd be a worry actually).
