-Fluent Bit 1.9 includes additional metrics features to allow you to collect both logs and metrics with the same collector. 
+Fluent Bit 1.9 and later includes additional metrics features to let you collect logs and metrics from a Prometheus-based endpoint at a set interval. These metrics can be routed to metric supported endpoints such as [Prometheus Exporter](../outputs/prometheus-exporter.md), [InfluxDB](../outputs/influxdb.md) or [Prometheus Remote Write](../outputs/prometheus-remote-write.md).

These metrics can be routed to metric supported endpoints such as [Prometheus Exporter](../outputs/prometheus-exporter.md), [InfluxDB](../outputs/influxdb.md), or [Prometheus Remote Write](../outputs/prometheus-remote-write.md)

 ## Example
 
-If an endpoint exposes Prometheus Metrics we can specify the configuration to scrape and then output the metrics. In the following example, we retrieve metrics from the HashiCorp Vault application.
