Logging API response and custom messages to reports and log files

[priyankamohile]

Hello,

I'm currently using NBomber version 4.1.2 to load test my web application. I wish to load test APIs, with the below parameters logged -

• API name
• Status code
• Requests failed
• Requests with OK response
• A custom message that is being read from the API response

The code I am using is as follows, with the string 'apiResponse' being the message that I wish to include in my NBomber logs. Is there any way of achieving this requirement?

static void Main(string[] args)
{
    var httpClient = new HttpClient();
    var apiResponse = "";

    var scenario = Scenario.Create("hello_world_scenario", async context =>
    {            
        var request =
            Http.CreateRequest("GET", "http://localhost/myapp/performance");

        var response = await Http.Send(httpClient, request);
        apiResponse = response.Payload.Value.Content.ReadAsStringAsync().Result;
        return response;
    })
    .WithoutWarmUp()
    .WithLoadSimulations(
        //Adjust the rate depending on the number of requests you wish to fire.
        Simulation.Inject(rate: 100,
                          interval: TimeSpan.FromSeconds(1),
                          during: TimeSpan.FromSeconds(30))
    );

    NBomberRunner
        .RegisterScenarios(scenario)
        .WithLoggerConfig(() =>
new LoggerConfiguration()
    .MinimumLevel.Debug()
    .WriteTo.File(
        path: "E:\\NBomber\\my-log-file.txt",
        outputTemplate:
        "{Timestamp:yyyy-MM-dd HH:mm:ss.fff zzz} [{Level:u3}] [ThreadId:{ThreadId}] {Message:lj}{NewLine}{Exception}",
        rollingInterval: RollingInterval.Day)
        // buffered: true)

) .Run(); }

Hi @priyankamohile Is it something like tracing? https://nbomber.com/docs/protocols/http#tracing-http-requests

Hi @AntyaDev , Yes, my requirement is similar to the above ask. Basically, we are load balancing our API calls and have multiple servers set up, the requests can flow to any of these servers. I'm looking at monitoring how many requests went to each of these servers.

@priyankamohile If it's about calculating how many requests each server handled, would it be possible to use a status code? For example:

return Response.Ok(statusCode: "OK server 1")

or if the response from server 2

return Response.Ok(statusCode: "OK server 2")
