Adding the human=true parameter is useful, but it only seems to be applied
to the byte counts. For example, when looking at my local MacBook's running
instance, and isolating just the process and Java information, the "heap_init"
: "256mb" is added to reflect the "heap_init_in_bytes" : 268435456 value.
However, the "start_time" : 1393519068785 is completely unreadable to all
but the very rarest of humans. It would be nice to see "start_time_human" :
"2014-02-27T16:37:48.785Z" in addition.
And the "refresh_interval" : 1000 is readable, but it would be nice if it
had a human readable form of "refresh_interval_human" : "1s" in addition.
