%description
jmxtrans is very powerful tool which reads json configuration files of servers/ports and jmx domains - attributes - types.
Then outputs the data in whatever format you want via special 'Writer' objects which you can code up yourself.
It does this with a very efficient engine design that will scale to querying thousands of machines.
