**Kibana version** : 6..8.0 Hi, I am trying to instrument a .net core web application using elastic and am running into some issues. I am able to see metric data ( cpu/ memory ) but am unable to see any transactions. I'm running a .NET Core 2.1 application on Ubuntu 18.04. These are my settings "ElasticAPM":{ "ServerUrls" : "[https://apm-stage](https://apm-stage).\*\*\*\*.com:8200", "ServiceName": "dd\_dev", "MetricsInterval": "1s", "TransactionSampleRate": 1.0, "Environment": "staging" } This is what I see when logs are turned on { "time": "2019-09-11 14:28:33.1157", "level": "DEBUG", "nested": { "message": "init main" } } { "time": "2019-09-11 14:28:34.7749", "level": "WARN", "nested": { "message": "{MicrosoftExtensionsConfig} Service name provided in configuration is dd\_dev" }, "{Scope}": "MicrosoftExtensionsConfig", "ServiceName": "dd\_dev" } { "time": "2019-09-11 14:28:34.7851", "level": "INFO", "nested": { "message": "{MicrosoftExtensionsConfig} The agent was started without a service version.

Hi @apm_user, welcome to discuss! Based on the logs you pasted here I don't see any transaction captured by the agent - so it seems to either go wrong very early, or capturing transactions is not turned on. How did you activate the agent? Do you use the `UseAllElasticApm()` method as described [here](https://www.elastic.co/guide/en/apm/agent/dotnet/current/setup.html)? ---

I am using Elastic.Apm.AspNetCore and this is the code in Startup() app.UseElasticApm(config); ---

> I am using Elastic.Apm.AspNetCore and this is the code in Startup() > app.UseElasticApm(config); That seems ok, assuming it's in the 1. line of the `Configure` method. One suggestion: Use the `UseAllElasticApm` from the `Elastic.Apm.NetCoreAll` package, that turns on every agent component, although `UseElasticApm` should also capture incoming HTTP request as transaction. Just to make sure we are on the same page: with that the agent will capture the incoming HTTP request to your [ASP.NET](http://ASP.NET) Core app as transactions, for manually creating transactions you need to use the [public agent api](https://www.elastic.co/guide/en/apm/agent/dotnet/current/public-api.html). Can you maybe also paste a log here where you turn both the [ASP.NET](http://ASP.NET) Core log level and the elastic apm log level to `Trace` and make sure that there are some HTTP requests in the timeframe of the logs? ---

@GregKalapos , I am able to see transactions,after moving up UseAllElasticAPM to line 1. Is there a reason it needs to be set before everything else ? ---

> I am able to see transactions,after moving up UseAllElasticAPM to line 1. Is there a reason it needs to be set before everything else ? Glad to hear that! We recommend `UseAllElasticApm` being the 1. line because we want to make sure it's the 1 middleware that gets registered, otherwise the duration of the transaction can be inaccurate. On the other hand if it's not in the 1. line the agent still should record transactions, so that's strange. I opened a [GitHub issue](https://github.com/elastic/apm-agent-dotnet/issues/489) to investigate this further. If you have a small reproducer that would help a lot. But overall I guess the problem is solved, right? ---

@GregKalapos , Yep, The problem is solved. Thanks for your help! Unfortunately, I don't have a small reproducer. I can post part of code of that helps. ---

Great! Yes, if you could post part of the code that'd help. Either directly on the [GitHub issue](https://github.com/elastic/apm-agent-dotnet/issues/489) or here. ---

Sorry for the delay, Here is the code ``` public void Configure Services(IServiceCollection service ) { services.AddMvcCore() .AddJsonFormatters() .AddApiExplorer() .AddJsonOptions(options => { options.SerializerSettings.ReferenceLoopHandling = ReferenceLoopHandling.Ignore; });; services.Configure(options => { options.ForwardedHeaders = ForwardedHeaders.XForwardedFor | ForwardedHeaders.XForwardedProto; }); services.AddSwaggerGen(c => { c.SwaggerDoc("v1", new Info { Title = "example API", Version = "v1", Description = "Example", Contact = new Contact() { Name = "Distribution Developers", Email = "" } }); c.ExampleFilters(); }); // Add Scoped and Singleton services here services.AddOptions(); ``` } public void Configure(IApplicationBuilder app, IHostingEnvironment env) { var config = new ConfigurationBuilder() .AddJsonFile("appsettings.json", false) .Build(); ``` app.UseForwardedHeaders(); if (env.IsDevelopment()) { app.UseDeveloperExceptionPage(); } var swaggerSettings = new SwaggerSettings(); config.GetSection("Swagger").Bind(swaggerSettings); app.UseSwagger(c => { c.PreSerializeFilters.Add((swagger, httpReq) => swagger.Host = httpReq.Host.Value); c.RouteTemplate = swaggerSettings.RouteTemplate; }); app.UseSwaggerUI(c => { c.RoutePrefix = swaggerSettings.RoutePrefix; c.SwaggerEndpoint(swaggerSettings.SwaggerEndpoint, "Characteristics API V1"); }); app.ConfigureExceptionHandler(_logger); app.UseMvc(routes => { routes.MapRoute("default", "api/{controller=Home}/{action=Index}/{id?}"); }); app.UseAllElasticApm(config); } ``` ---
