Does Fly's Prometheus API endpoint support federation? `remote_read`?

Hi @DazWilkin,

Fly’s Prometheus API runs on VictoriaMetrics Cluster and supports all of the Prometheus querying API endpoints documented there.
VictoriaMetrics notably does not support the remote_read API, but federate should be supported.

Your curl federate example has a syntax error, the match[] should be passed as a URL parameter (not part of the path), and you need to either URL-encode all URL-unsafe chars or pass the param as url-encoded POST data, either:

  • /federate?match[]=%7B__name__=~%22.%2B%22%7D
  • /federate --data-urlencode 'match[]={__name__=~".+"}'
