------------------------------------------
Summary: Add a server start time metric
Key: KAFKA-7992
URL: https://issues.apache.org/jira/browse/KAFKA-7992
Project: Kafka
Issue Type: Improvement
Reporter: Stanislav Kozlovski
Assignee: Stanislav Kozlovski
KIP: KIP-436
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.
