It's normally used for prometheus to send data that it has already collected to some remote archival database: https://prometheus.io/docs/prometheus/latest/storage/#remote-storage-integrations i.e. when prometheus is the remote write client. That's fine. The ability to use prometheus itself as a remote write endpoint is, to all intents and purposes, undocumented: it's mentioned in passing here <https://prometheus.io/docs/prometheus/latest/feature_flags/#remote-write-receiver>. I *strongly* discourage you from attempting to use it. This is not how prometheus is intended to be used, and you're likely to end up in a world of pain.
