Quick start guide

##Steps:

• add reference to performance counters library;
• define category with required counters:

internal class TestSingleInstance: SingleInstanceCategoryWrapper
{
    public TestSingleInstance() : base("SingleInstance", "For tests") { }

    [Counter("Test NumberOfItemsCounter")]
    public NumberOfItemsCounter Count { get; private set; }
}

• define your counters container (if you need a singleton):

internal class PerfCounters: Qoollo.PerformanceCounters.PerfCountersContainer
{
    private static TestSingleInstance _singleInstance = CreateNullCategoryWrapper<TestSingleInstance>();
    public static TestSingleInstance TestSingle { get { return _singleInstance; } }

    public static void Init(CategoryWrapper parent)
    {
        _singleInstance = parent.CreateSubCategory<TestSingleInstance>();
    }
}

• create counters factory on application start-up and initialize you PerfCounters container:

var counterFactory = new WinCounterFactory();
// or load from App.config:
// var counterFactory = PerfCountersInstantiationFactory.CreateCounterFactoryFromAppConfig("PerfCountersConfigurationSection");

PerfCounters.Init(counterFactory.CreateRootWrapper());
counterFactory.InitAll();

• use counters anywhere you want:

PerfCounters.TestSingle.Count.Increment();

• don't forget to dispose counters factory when application is closing:

counterFactory.Dispose();
