> As with all software systems, observability into their health is critical.
> With many deployment platforms (be them custom-built or open-source), tasks like restarting
a misbehaving server in a cluster are completely automated. With Kafka, monitoring systems
have no definitive source of truth to gauge when a server/client has been started. They are
left to either use arbitrary Kafka-specific metrics as a heuristic or the JVM RuntimeMXBean's
StartTime, which is not exactly indicative of when the application itself started
> It would be useful to have a metric exposing when the kafka server has started.
