I will deliver keynotes for (free) Oracle Code conferences in London, Berlin, Prague and Brussels. The deal was: slideless content. The advantage is: the content (=code) will vary across cities and is
going to be influenced by the attendees.
firehose connects to (micro) services (Thin WARs), gathers monitoring data and provides it in prometheus-compliant format. Lacking metadata
can be provided via environment variables at docker start or via HTTP / JSON at runtime. New endpoints can be re-configured on-the-fly.
One firehose instance can handle multiple endpoints. Firehose is a 16 kB Java EE 7, zero dependency, Thin WAR.
