What it is

Metrics.NET library is a .NET Port, with lots of additional functionality, of the awesome Java metrics library by Coda Hale.

To paraphrase the Java library description - Metrics is a library which gives you unparalleled insight into what your code does in production. Metrics provides a powerful toolkit of ways to measure the behavior of critical components in your production environment.

What it does

It can measure things like how long requests take, how often errors occur, how many items are in a cache and how often the cache is hit. It can measure any measurable aspect of the host application.

One of the main goals of the library is to have a minimal impact on the measured application, while at the same time making it easy to capture the desired metrics. A lot of effort has been invested in making the public API as simple and intuitive as possible.

Supported runtimes: .NET 4.5.1, .NET 4.5, .NET 4.0 (on a separate branch) & Mono 3.8.0+ ( tested on OsX ).

Who is it for

Developers who need to see what is happening inside their systems at run-time.

Any application, from a long running service to a web app to a console app can benefit from measuring what is happening while it is running.

For a very good introduction on why metrics are necesary I highly recommand Coda Hale's talk about metrics and slides.

Why another port

This port is also inspired and contains some code from Daniel Crenna's port of the same library.

I have decided to write another .NET port of the same library since Daniel does not actively maintain metrics-net. I've also wanted to better understand the internals of the library and try to provide a better API, more suitable for the .NET world.

Visualization Demo

The visualization app is also avaliable on github: Metrics.NET.FlotVisualization.

A demo of the visualization app is available here. This demo uses fake, generated values for the metrics.
