Is it possible to sanitize the following pieces of information? I've added them to the SanitizeFieldNames setting, but they still come over.

```auto
client.ip
http.request.socket.remote_address
user.name

```

Thanks!

Hi @danbrad, welcome on discuss!

In the [`SanitizeFieldNames`](https://www.elastic.co/guide/en/apm/agent/dotnet/current/config-core.html#config-sanitize-field-names) you can define keys that will be checked when the agent reads HTTP headers or the request body when it's form-urlencoded.

The things you list typically don't come from those sources, that's why those still come over.

What you can do is to use the [Filter API](https://www.elastic.co/guide/en/apm/agent/dotnet/current/public-api.html#filter-api) and set those properties to `null`.
