Tsdb-gw gone?

[deniszh]

Hello!
Could you please suggest software to put metrics to Kafka? I used https://github.com/raintank/tsdb-gw/ before, but now repo is gone for some reason.
https://github.com/grafana/carbon-relay-ng is not supporting V2 format (and I didn't manage to make it work at all)

Metrictank now has the mt-gateway utility to replace tsdb-gw: https://github.com/grafana/metrictank/tree/master/cmd/mt-gateway

Ah, missed that somehow. But I do not see carbon interface there. And auth / multi-tenancy support :(

What's the reason of hiding tsdb-gw? It's still mentioned in MT documentation...

for a carbon input, carbon-relay-ng works much better as it's designed for carbon. tsdb-gw was too specific to our internal infra (e.g. auth using grafana.com), mt-gateway replaces it as a more generic tool, but you're right we should clean up our docs and it also doesn't have auth (yet). What kind of auth are you looking for? do you need integration with any particular system?

carbon-relay-ng has on open issue to add the new MetricPoint format, btw. i envision it would use the same library as mt-gateway.

Auth is not neeeded in our usecase, you're right. But lack of MetricPoint not making carbon-relay-ng drop in replacement for tsdb-gw either.

In my opinion mt-gateway needs some kind of authentication to provide the multi tenancy that tsdb-gw provided.
Without a tool that resolves authenticated queries to a specific set of org id's the multi tenancy of metrictank is gone.

Without tsbd-gw we had to give direct access to metrictank and the users had to define the x-org header in the grafana datasource, but this would also grant them access to any org they want.

Authentication + setting the x-org header was and is the main use case of tsdb-gw for me.
