in signoz helm chart, is there a way to secure the otel collector endpoint (exposed via gRPC) ?

please follow this https://signoz.io/docs/tutorial/setting-up-tls-for-signoz/

@nitya-signoz I mean can we use some sort of authorization on the collector endpoint ?

So ingestion keys along with rate limiting are available only in enterprise edition and cloud.

ok

Not being able to secure ingestion endpoints is a huge downside for signoz self hosted :(

@Prashant Shahi can a username-password restriction be achieved easily on OSS version?

It is possible to set it up using OTEL native solution with

basicauth

extension or non-OTEL solution like nginx matching auth headers.
