I’m writing a small exporter for a custom service, does anyone know what an exporter’s /metrics should return when requests to the underlying service fail entirely, and so no metrics can be returned?

Hrm… presumably a 50x status code. Found this, but it might be fore the general promethus api a dn not the exporter api. https://prometheus.io/docs/prometheus/latest/querying/api/
