How to add APM agent in .NET

Juan_David_Jaramillo · August 10, 2021, 11:16pm

hello, how are you?
I have a problem adding the APM agent to my web application, I installed the agent from the NuGet, I created a class called 'Startup' as indicated in the documentation and also created the configuration file 'appsettings.json', configure as the documentation says with the url and token, I run the web application, but I am not sending data to my APM in kibana, I have already looked at several sources but I still do not know how to correct it, so I need your help please.
I attach screenshots of the code interface and the raw code as such:

Startup.css

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using Microsoft.AspNetCore.Builder;
using Microsoft.AspNetCore.Hosting;
using Microsoft.AspNetCore.Http;
using Elastic.Apm.NetCoreAll;
using Microsoft.Extensions.Configuration;


namespace VentasWeb
{
    public class Startup
    {
        public void Configure(IApplicationBuilder app, IHostingEnvironment env)
        {
            app.UseAllElasticApm();
            //…rest of the method
        }
        //…rest of the class
    }
}

appsettings.json

{
  "ElasticApm": {
    "SecretToken": "xxxxxxxxxxxxxxxxxxx",
    "ServerUrls": "https://d2349e51823d44eaa0c3af1ba3601b5d.apm.us-central1.gcp.cloud.es.io:443", //Set custom APM Server URL (default: http://localhost:8200)
    "ServiceName": "MyApp" //allowed characters: a-z, A-Z, 0-9, -, _, and space. Default is the entry assembly of the application
  }
}

Hey @Juan_David_Jaramillo,

A good first thing to check would be the agent logs. Setting the log level to Trace in appsetttings.json with

{
  "ElasticApm": {
    "SecretToken": "xxxxxxxxxxxxxxxxxxx",
    "ServerUrls": "https://d2349e51823d44eaa0c3af1ba3601b5d.apm.us-central1.gcp.cloud.es.io:443",
    "ServiceName": "MyApp",
    "LogLevel": "Trace"
  }
}

will provide verbose information to troubleshoot with. If the application is using Microsoft.Extensions.Logging, the APM agent will create a logger with category name "Elastic.Apm" using the ILoggerFactory. If the application isn't using Microsoft.Extensions.Logging, the APM agent logger with log to Console.Out.

If you're able to provide some log output for agent operation, we can see what's going on.

Good, I have attached the code as you say it, but when I run the application does not create the agent in my kibana. I do not know if this misplaced the class or something, I send capture.

@Juan_David_Jaramillo is this an ASP.NET Core app, or a classic (old) ASP.NET Application running on full framework?

I suspect this is a classic ASP.NET app on Full Framework since you say

I created a class called 'Startup' as indicated in the documentation and also created the configuration file 'appsettings.json',

In ASP.NET Core, those should be there by default, that's what makes me think maybe you are just looking at the wrong part of the docs.

Here is the relevant part for ASP.NET Classic (so the one which is not for ASP.NET Core).

Juan_David_Jaramillo · August 11, 2021, 4:31pm

ready, I have already done what the documentation says add the agent and run the application and everything is fine, but I do not know why I still do not get the data in kibana, this is how the config is:

Web.config:

  </connectionStrings>

MvcApplications:
I created a class in the app_start as it says in the documentation, I don't know if it is well placed.

using Elastic.Apm;
using Elastic.Apm.Api;
using Elastic.Apm.AspNetFullFramework;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;

namespace VentasWeb.App_Start
{
    public class MvcApplication : HttpApplication
    {
        protected void Application_Start()
        {
            // other application startup e.g. RouteConfig, etc.

            // set up agent with components
            var agentComponents = ElasticApmModule.CreateAgentComponents();
            Agent.Setup(agentComponents);

            // add transaction filter
            Agent.AddFilter((ITransaction t) =>
            {
                t.SetLabel("foo", "bar");
                return t;
            });
        }
    }
}

I don't know if it goes in that folder

GregKalapos · August 11, 2021, 5:13pm

I think the issue is that this is an ASP.NET classic application, which won't pick up your apsettings.json file, therefore settings from that file are ignored. Again, if I understand the situation correctly, then you only need to follow this doc, and you don't need to follow the doc for ASP.NET Core.

Could you try to copy the ServerUrls and the SecretToken configs from your apsettings.json file into the web.config file similar to this doc?

Juan_David_Jaramillo · August 11, 2021, 5:19pm

Ok, There it is, I have already:

The error log indicates that the resource at

https://d2349e51823d44eaa0c3af1ba3601b5d.apm.us-central1.gcp.cloud.es.io/config/v1/agents?service.name=VentasWeb_Clr4IntegratedAppPool
