Howto monitor object creations

jaap.q42jaap.q42 Posts: 36 Bronze 2
I'm using the memoryprofiler to track down memleaks we've been experiencing. I've pinpointed the type of object that is being held into memory.
We're using Lucene which does a lot of internal caching.

Can I use Memory profiler to see at what time an object is created?

I know the CLR Profiler claims to be able to provide this info:
"Which methods allocate which types of objects?"

But I can't get the CLR profiler to work, and there's no chance of any support on that tool.

Hope someone can help me!

    Hi Jaap,

    the simple answer is "no" (sorry) but I think you can set Visual Studio to break on the constructor of this object (using "break on function" feature)?

    Hi Chris,

    I'm using Visual Web Developer 2008. I couldn't find how to run a debugger and the memory profiler at the same time. Do you know whether it's possible?

    Also, you may sometimes want to profile a class which in located in de System namespace. How would you set trigger a break point then?


    "Off topic":

    So maybe a new feature in ANTS Memory Profiler 6 could be that you can navigate from an instance in the instance list back to the reference graph, filtering just 1 object.
    From my point of view this should be possible since the Profiler already filters objects, why not allow a single-object filter which can be activated from the instance list!

    Anyway, I might be saying something that's technically not possible, or maybe nobody else is interested in such a feature...

    Sure- I would use WinDbg and attach it to your process (run under ANTS). But I don't think there is any necessity to run them simulatneously. Profiling and debugging can always be successfully done serially I would say.

    To access System code, you may wish to check out Reflector PRO:

    I'm sorry- I don't understand this feature :(
