NotifyIfTakesMoreThan

NotifyIfTakesMoreThan

// Sometimes it's easier to make assumptions about performance as a trade off for simplified code, but why not make it easy to notify us when that assumption is violated?  Next step might be StopAndNotify

// Usage

using (new NotifyIfTakesMoreThan(TimeSpan.FromMinutes(5), "XYZ Import - checking all data instead of more complex code to optimize it"))
{
	//operation
}

// Implementation
public class NotifyIfTakesMoreThan : IDisposable
{
	private readonly TimeSpan _NotificationThreshold;
	private readonly string _Description;
	private readonly Stopwatch _StopWatch;
	private static readonly ILog Log = LogManager.GetLogger(typeof (NotifyIfTakesMoreThan));

	public NotifyIfTakesMoreThan(TimeSpan notificationThreshold, string description)
	{
		_NotificationThreshold = notificationThreshold;
		_Description = description;
		_StopWatch = new Stopwatch();
		_StopWatch.Start();
	}

	public void Dispose()
	{
		_StopWatch.Stop();
		if (_StopWatch.Elapsed > _NotificationThreshold)
		{
			Log.Error("Operation exceeded threshold: " + new {_Description, _NotificationThreshold, _StopWatch.Elapsed});
		}
	}
