The stream state and replica info is only guaranteed to be accurate when returned by the leader of a given stream. This new option returns stream details only for the stream in which the server is the leader for that stream. For systems with many streams this can significantly reduce the amount of data returned when scraping across all servers since non-leader details will likely be ignored. Fix #5698

Proposed change
Add a
stream_leader(other names welcome) filter option to theJszOptionsto reduce the data ofstream_detailto only include data where the server being pinged is the leader of streams.Use case
For systems having a lot of JetStream assets, this will reduce the overall resources use on the server as well as the data sent to the client.
