#1 trying to port jamon to C++, C#

[Anonymous]

I am in the process of trying to create a thread safe
version that is very basic and provides me with the
following details,

Hits, avg ms, total ms, min ms, max ms, active,average
active, max active, first access, last access, 0-10ms,
11-20ms etc.(No Primary)
The time ranges/buckets will simply have a count of
the hits that fell in that range and not the other
details.

Do you have a basic source code in java to help me get
started.(as described in your JAMon Challenge #2)

In an attempt to port to .NET, I compiled the jamon
1.0 java code using J# and created a DLL that can be
used by .NET apps in other languages. This works
without any issues.

I tried doing the same for 2.0, but J# did not
recognize ThreadLocal, and also found some references
on the web to not use ThreadLocal in a managed
environment(App Server).

se_thread.html
did not spend enough time on this.

But porting to C++ is another issue, so getting
started with a very simple version would be nice

Thanks

I can help you with both versions of say .Net and C++.

You can always get the code from CVS.

Here is the link:
http://jamonapi.cvs.sourceforge.net/jamonapi/jamonapi/src/java/com/jamonapi/

I suggest for C++ we start small, and have something pretty
basic. Does c++ support synchronization?

So you have a working version of JAMon 1.0 in .Net?

The .NET version is a simple recompile of jamon1.0 in J# to
produce a .NET dll that can be used in any .NET apps.
Tested it in a C# app and works fine.

On the port to C++ front, I have actually started to create
a very basic prototype of jamon in java, so a C++/C# or any
other language developer can look at it to get started.
This should be ready pretty soon, will pass it on to you,
and all it implements is the .start()/.stop() & a simple
form of getReport().

For your c++ version here is a simple version from when i
started working on jamon 2.0. The oldest version is the
most simple and each version subsequently adds features. It
might be good to cross check it with your implementation.

Can you send me a report of your reports in the .Net
version. Would be curious to see. Also would be nice to
post the generated code, how you generated it, and the
generated dll if you can have instructions for all that.
Appreciated.

you can probably download the J# express(I did that in a
prior version of Visual Studio)
http://msdn.microsoft.com/vstudio/express/visualj/ and
simply drop in all your 1.0 java files and when you build,
it creates a DLL. There was no source changes required for
1.0. I had sent you the dll a loong time ago(when you were
not hosted on sourceforge), will resend it to the
sourceforge address or create a new support request as I do
not see a way to upload a file now. Once the .NET
application adds the dll as a reference, they have access
to all classes of jamon and use it just like any other
class.

I have created my simple implementation, which I think is
probably similar to your trial code, and I did not spend
too much time on it, so is not fully optimized. Will send
that to you aswell to your sourceforge.net email address.
