实现起来很简单，一个Filter就可以搞定！！！
/// <summary>
/// 监控接口执行时间
/// </summary>
public class TimingActionFilter : ActionFilterAttribute
{
private static readonly Logger logger = LogManager.GetCurrentClassLogger();
private const string Key = "__action_duration__"; /// <summary>
/// 启用计时器
/// </summary>
/// <param name="actionContext"></param>
/// <param name="cancellationToken"></param>
/// <returns></returns>
public override Task OnActionExecutingAsync(HttpActionContext actionContext, CancellationToken cancellationToken)
{
/*
await Trace.WriteAsync("Executing action named {0} for request {1}.",
actionContext.ActionDescriptor.ActionName,actionContext.Request.GetCorrelationId());
*/
if (SkipLogging(actionContext))
{
return base.OnActionExecutingAsync(actionContext, cancellationToken);
}
var stopWatch = new Stopwatch();
actionContext.Request.Properties[Key] = stopWatch;
stopWatch.Start();
return base.OnActionExecutingAsync(actionContext, cancellationToken);
} /// <summary>
/// 记录监控接口执行日志
/// </summary>

public override Task OnActionExecutedAsync(HttpActionExecutedContext actionExecutedContext, CancellationToken cancellationToken)
{
if (!actionExecutedContext.Request.Properties.ContainsKey(Key))
{
return base.OnActionExecutedAsync(actionExecutedContext, cancellationToken);
}
var stopWatch = actionExecutedContext.Request.Properties[Key] as Stopwatch;
if (stopWatch != null)
{
stopWatch.Stop();
var actionName = actionExecutedContext.ActionContext.ActionDescriptor.ActionName;
var controllerName = actionExecutedContext.ActionContext.ActionDescriptor.ControllerDescriptor.ControllerName;
string log = string.Format("[execution controller：{0} - action：{1} take {2} time.]", controllerName, actionName, stopWatch.Elapsed);
#if DEBUG
Debug.Print(log);
#endif
logger.Info(log);
}
return base.OnActionExecutedAsync(actionExecutedContext, cancellationToken);
} private static bool SkipLogging(HttpActionContext actionContext)
{
return actionContext.ActionDescriptor.GetCustomAttributes<NoLogAttribute>().Any() || actionContext.ActionDescriptor.ControllerDescriptor.GetCustomAttributes<NoLogAttribute>().Any();
}
} /// <summary>
/// 不记录监控接口执行日志
/// </summary>
[AttributeUsage(AttributeTargets.Method | AttributeTargets.Class, Inherited = true)]
public class NoLogAttribute : Attribute
{ }
WebApiConfig中启用
public static void Register(HttpConfiguration config)
{
//启用监控接口执行时间
//config.Filters.Add(new TimingActionFilter());
//启用全局验证
config.Filters.Add(new ModelValidFilter());
//启用特性路由
config.MapHttpAttributeRoutes(); //默认路由
config.Routes.MapHttpRoute(
name: "DefaultApi",
routeTemplate: "api/{controller}/{id}",
defaults: new { id = RouteParameter.Optional }
);
}
配置NLog记录响应时间超过1秒的接口服务
