#About nwiretap NWiretap is a set of simple tools to monitor points of interest inside your .NET Applications

Create a class with a set of instruments:

public class HomeController : Controller
{
    private static readonly IMeter Meter = Instrument.Meter(typeof(HomeController), "General performance", "Index hits", 3000);
    private static readonly IInvocationTimer Timer = Instrument.Timer(typeof(HomeController), "General performance", "Database fetch", 3000);
    private static readonly ILogger Logger = Instrument.Logger(typeof(HomeController), "General logging", "Log output", 20);
        
    public ActionResult Index()
    {
        Meter.Tick();
        var s = Timer.Time(() => Database.GetSomeStuff());

        Logger.Log("Index was hit");
        return View();
    }
}

The measurements can then be obtained as JSON by acessing /nwiretap (this url is configurable) on your application:
