@ -129,8 +129,15 @@ If a scrape target is not providing the correct Content-Type header the
fallback protocol can be specified using the `fallback_scrape_protocol`
parameter. See [Prometheus scrape_config documentation.](https://prometheus.io/docs/prometheus/latest/configuration/configuration/#scrape_config)
This is a breaking change as scrapes that may have succeeded with Prometheus v2
may now fail if this fallback protocol is not specified.
This is a **breaking change** as scrapes that may have succeeded with Prometheus v2
may now fail if this fallback protocol is not specified. Make sure your scrape
endpoints respond with one of the supported Content-type headers:
- `application/vnd.google.protobuf;proto=io.prometheus.client.MetricFamily;encoding=delimited`
- `text/plain;version=0.0.4`
- `text/plain;version=1.0.0`
- `application/openmetrics-text;version=0.0.1`
- `application/openmetrics-text;version=1.0.0`
