Remote Write to another Prometheus

[Dirk Fries]

Hi @all,

I'd like to send all my metrics from one "main" Prometheus to another one.

I have already found and configured other remote write connections (e.g. to Postgres) but I just can't find a way to do a remote write to another Prometheus.

Does anyone have a hint for me ?

Thanks a lot !

Bye, Dirk

You can't use remote write for this. Instead you can use federation, but
in general it isn't recommended to copy all metrics from one Prometheus
to another.

Prometheus does not receive it reads/polls, you have two solutions, either to use federation as Stuart said, or you point remote read of the "receiver" instance into the `sender:9090/api/v1/read`.

The second solution will query the data on demand (it won't move the data to the second Prometheus)

You can remote write to an instance of Victoria Metrics, which provides a query API identical to Prometheus.  This means it looks like another prometheus server to all intents and purposes (e.g. you can add it as a prometheus data source in grafana).  The only thing I'm not sure about is whether it can handle alerting rules yet.
