EpThreshold

EpThreshold is a tiny middleware for Asp.Net Core which can be used to take action on requests which takes longers than a given threshold. Such action could for example be to log the request in order to track unexpectedly demanding requests in order to optimize them.

Startup.cs

public void Configure(IApplicationBuilder app, IWebHostEnvironment env)
{
    ....
    
    app.UseEpThreshold(o =>
    {
        o.Threshold = 1300; // The default threshold in ms for an endpoint. If a request takes longer than this the ThresholdMetAction will be invoked.
        o.ThresholdMetAction = async (ThresholdLogModel model) => await _queueClient.SendAsync(model);
    });

    ....
}

If you want to set a custom threshold on an endpoint you can use the Attribute [Threshold(100)].

[Threshold(100)] //if the request takes any longer than 100 ms, invoke ThresholdMetAction
[HttpGet("GetWeatherForecast/{id}")]
public async Task<WeatherForecast> GetWeatherForecast(int id)
{
    ....
}
