**Kibana version** :  
7.17.9

**APM Server version** :  
`8.8.1`

**APM Agent language and version** :  
.net core C# =\> Elastic.Apm.NetCoreAll 1.26.0 and Serilog.Sinks.Elasticsearch 9.0.0

**Description of the problem including expected versus actual behavior. Please include screenshots (if relevant)**:

I've registered apm in program.cs  
app.UseAllElasticApm(app.Configuration);

I am also using Serilog and logging all my Application Logs to ES with Serilog.  
That works all fine. But since I am using APM it registered a lot of "HttpDiagnosticsSubscriber" on startup and my current debuglog on my console and on the ES Server in my Application Log looks like:

```auto
[15:30:43 INF] {RequestPipelineDiagnosticsListener} Received an CallElasticsearch.Start event from elasticsearch
[15:30:43 INF] {HttpConnectionDiagnosticsListener} Received an SendAndReceiveHeaders.Start event from elasticsearch
[15:30:43 INF] {HttpConnectionDiagnosticsListener} Received an SendAndReceiveHeaders.Stop event from elasticsearch
[15:30:43 INF] {HttpConnectionDiagnosticsListener} Received an ReceiveBody.Start event from elasticsearch
[15:30:43 INF] {HttpConnectionDiagnosticsListener} Received an ReceiveBody.Stop event from elasticsearch
[15:30:43 INF] {RequestPipelineDiagnosticsListener} Received an CallElasticsearch.Stop event from elasticsearch
[15:30:45 INF] {RequestPipelineDiagnosticsListener} Received an CallElasticsearch.Start event from elasticsearch
[15:30:45 INF] {HttpConnectionDiagnosticsListener} Received an SendAndReceiveHeaders.Start event from elasticsearch
[15:30:46 INF] {HttpConnectionDiagnosticsListener} Received an SendAndReceiveHeaders.Stop event from elasticsearch
[15:30:46 INF] {HttpConnectionDiagnosticsListener} Received an ReceiveBody.Start event from elasticsearch
[15:30:46 INF] {HttpConnectionDiagnosticsListener} Received an ReceiveBody.Stop event from elasticsearch
[15:30:46 INF] {RequestPipelineDiagnosticsListener} Received an CallElasticsearch.Stop event from elasticsearch
[15:30:48 INF] {RequestPipelineDiagnosticsListener} Received an CallElasticsearch.Start event from elasticsearch
[15:30:48 INF] {HttpConnectionDiagnosticsListener} Received an SendAndReceiveHeaders.Start event from elasticsearch
[15:30:48 INF] {HttpConnectionDiagnosticsListener} Received an SendAndReceiveHeaders.Stop event from elasticsearch
[15:30:48 INF] {HttpConnectionDiagnosticsListener} Received an ReceiveBody.Start event from elasticsearch
[15:30:48 INF] {HttpConnectionDiagnosticsListener} Received an ReceiveBody.Stop event from elasticsearch
[15:30:48 INF] {RequestPipelineDiagnosticsListener} Received an CallElasticsearch.Stop event from elasticsearch
[15:30:50 INF] {RequestPipelineDiagnosticsListener} Received an CallElasticsearch.Start event from elasticsearch
[15:30:50 INF] {HttpConnectionDiagnosticsListener} Received an SendAndReceiveHeaders.Start event from elasticsearch
[15:30:50 INF] {HttpConnectionDiagnosticsListener} Received an SendAndReceiveHeaders.Stop event from elasticsearch

```

It spams my hole Application log. Is there a way to disable this kind of logs for my Application ES Log Index?

I've tried to Override this in the appsettings.json but its not working:

```json
{
  "AppName": "automation-api",
  "Serilog": {
    "MinimumLevel": {
      "Default": "Information",
      "Override": {
        "Microsoft": "Warning",
        "System.Net.Http.HttpClient": "Warning",
        "System": "Warning",
        "*HttpHandlerDiagnosticListener*": "Warning",
        "*RequestPipelineDiagnosticsListener*": "Warning"
      }
    }
  },
  "ElasticApm": {
    "ServerUrl": "https://elastic-apm.local.com",
    "ServiceName": "automation-api",
    "Environment": "development",
    "TransactionSampleRate": 1.0,
    "LogLevel": "Debug",
    "CaptureBody": "errors"
  },
  "AllowedHosts": "*"
}

```

The problem is that we use the nuget "Serilog.Sinks.Elasticsearch" which is not from ES itself and this makes this passive Problems.

We Megrated to Elastic.Serilog.Sinks and this solved our Problem

Hi,

How can we pass the extra configuration (including API Key for ES authentication) while using Elastic.Serilog.Sinks?

Thanks,
