Log method execution time with .NET annotation

Question

Is there any existing library to log the method execution time (I prefer serilog, anotar. serilog) just with method annotation?

Answer 1

If your intention is to log elapsed time of the Controller/Action. You can write your own Middleware for this purpose. check the example below:

public class DiagnosticsMiddleware 
{
    private readonly RequestDelegate _next;

    public DiagnosticsMiddleware(RequestDelegate next, IElasticClient esClient)
    {
        _next = next;
        _esClient = esClient;
    }

    public async Task Invoke(HttpContext context)
    { 
        Stopwatch sw = Stopwatch.StartNew();


        await _next(context);

        sw.Stop();
        var elapsedTime = sw.ElapsedTicks / (Stopwatch.Frequency / (1000L * 1000L));
        LogContext.PushProperty("ElapsedTime", elapsedTime);
    }

}

and you can configure it like

public void Configure(IApplicationBuilder app)
{
    app.UseMiddleware<ContextEnricherMiddleware>();
}
