new c7b5cf882f Add JSON stats to the status servlet
c7b5cf882f is described below
commit c7b5cf882fe847b3bc495d46bf188f8614be7b3e
Author: remm <r...@apache.org>
AuthorDate: Tue Oct 17 15:57:46 2023 +0200
Add JSON stats to the status servlet
The format is easy to parse and validate and is a straight equivalent to
the XML view.
I did not add the detailed processor view, it seems way to verbose these
days.
