Hello, I’m working in an environment that’s very Ruby heavy and I’ve never used ruby before. I need to be able to access Windows performance counters in from a Windows service is written in native Ruby (not IronRuby). I’m traditionally a C# and JAVA programmer. I was wondering if it might be possible for Ruby to be able to access the .Net System.Diagnostics performance counters via IronRuby. Of course, if there’s a much simpler way I’m all ears. I tried searching the forum and it seems my searching skills are not up to par and apologize if this has been already answered. Thanks in advance for any help. Ameer. ---

You can access System.Diagnostics via IronRuby. However, you will have to use the IronRuby interpreter to run your native ruby code, which is something I guess you are not willing to do (yet). Maybe you’d better look for a gem or a Ruby library that simplifies performance counter access… Thanks, Shay. * * * Shay F.

To access the .NET framework from MRI (the Ruby implementation you are currently using), your best bet is to use RubyCLR: [http://rubyforge.org/projects/rubyclr/](http://rubyforge.org/projects/rubyclr/). It is a native bridge between Ruby and the CLR, using Ruby’s Win32OLE support to talk directly to the CLR hosting APIs. ~js * * * From: removed\_email\_address@domain.invalid [removed\_email\_address@domain.invalid] on behalf of Ameer D.

I’ll see if I can find a gem that can do what I’m looking for. Thanks for the help. Ameer. ---

Hi there Jimmy, This looks very promising. Thanks very much for the pointer. Ameer.

To high speed access the .NET framework from Ruby you can write own Ruby extension on C++/CLI. So you can create custom wrapper for .NET class and optimize them for your needs. ---

Yeah, RubyCLR is that. ---

Hi there Shay, Using IronRuby to run the ruby code turned out to be easier than I thought. I’m able to run the code on IronRuby and access the System.Diagnostics namespace.
