How to access server-side response time for every API request

X-Response-Time Overview

When we are reviewing API metrics, we should understand what’s a duration on server-side without network latency.

Virto Commerce adds X-Response-Time header to responses for all API methods.

The response time is defined as the elapsed time from when a request enters the Platform to when the headers are written out to the client.

Implementation

The X-Response-Time middleware has been implemented as Global Filters that executed on all incoming requests to the API.

			System.Web.Http.GlobalConfiguration.Configuration.Filters.Add(new ResponseTimeHeaderFilter());
        }
    }
    /// <summary>
    /// Filter add X-Response-Time header to response contains elapsed response time in milliseconds 
    /// </summary>
    public class ResponseTimeHeaderFilter : System.Web.Http.Filters.ActionFilterAttribute
    {
        public override void OnActionExecuting(HttpActionContext actionContext)
        {
            actionContext.Request.Properties["X-Response-Time"] = Stopwatch.StartNew();
        }


        public override void OnActionExecuted(HttpActionExecutedContext actionExecutedContext)
        {
            object timer;
            if (actionExecutedContext != null && actionExecutedContext.Request != null && actionExecutedContext.Request.Properties.TryGetValue("X-Response-Time", out timer))
            {
                var stopWatch = timer as Stopwatch;
                if (stopWatch != null)
