How can I protect the requests? Something with an header token... what is the standard way?

@Srikanth Chekuri might be able to help here

@Enrico did you mean to say protect the signoz collector instance? You would have to enable one of the authentication extensions. It could simple static bearer token which can be shared b/w you instrumented app and collector or something like oatuh2 or oidc server which can issue them. When you setup ready on the collector instance you would update the prev message to use the

WithHeaders

options to send the token.

Yes, can you share some link/doc to these authentication extensions?

In this extensions list you can find them https://github.com/open-telemetry/opentelemetry-collector-contrib/tree/main/extension

Ty!
