Hi Sam,
I suggest you use the System.Diagnostics.Trace class as this will output
trace information in realtime, it can be viewed using a tool called Debug
Viewer
http://www.microsoft.com/technet/sys...DebugView.mspx
and also process monitor & process explorer, which gives more information
than task manager

Also if you want to check for a memory leaks in your application you should
check Rico Mariani's blog and especially the entry about examianing
application memory.

If you are looking for a memoery profiler check out the .Net profiler
available from MSDN, it's free
1.1

2.0

Another great profiler is Ants .Net Profiler, this will give you a 2 week
eval period.

Hello Ollie,
have you checked out the .Net Profiler API? there are loads of great
articles on the MSDN website:

Nope hadn't but now I have a starting place so shall be real soon. Thanks
As for your application are you using any logging and tracing? surely
you could increase the logging when you believe the application is
behaving in a strange manner.
I log all caught and uncaught exceptions .. but this has revealed nothing
.... I peppered the application with 'trace' points that gives me an idea
what it was doing at any given time. but I cant collect the right information
here ..
Why can't you use a memory profiler in product if you can't recreate
the problem in development?
I havent found any in-product ones yet that I could A) understand ... b)
Afford C) run on a machine in the production environment.(locked down PC's)
Thats not to say there isn't a product that fits the bill ... I just havent
found it yet.

Can any-one recommend some good sites detailing how to code a simple

profiler?
How do they "look under the hood"?
I built an uber simple service that tracks the process' memory but I
need to "get inside" and look a bit deeper and I don't have a clue
where to start ... a commercial memory profiler is not an option due
the nature of the environment the application is deployed in ..
My app runs fine for weeks (in 8 locations) but every now and again
it goes BOOOOOM Operator feedback is non-existent so how they do it
eludes me and it never ever misbehaves in the test environment.
So my plan is to automatically detect when the app is starting to
creep up and start looking inside to see what exactly is going on.
(its a plan of sorts)
If I dont go insane before then ...
