Fluent Bit 1.9 includes additional metrics features to allow you to collect both logs and metrics with the same collector.
The initial release of the Prometheus Scrape metric allows you to collect metrics from a Prometheus-based endpoint at a set interval. These metrics can be routed to metric supported endpoints such as Prometheus Exporter, InfluxDB, or Prometheus Remote Write
