Display status of a server instance
mps-status [-C [path/]server_name][--statistics|-s
[sample_interval]] [--json|-j]
mps-status [-C [ displays
the status of the server (path/]server_name][--statistics|-s
[sample_interval]] [--json|-j]STARTED, STOPPED),
along with a full path to the server instance. Additionally, it can
display performance statistics about the server including:
sample interval in milliseconds
CPU utilization
number of active worker processes
number of requests in queue
memory usage
request throughput per second
total queue time in milliseconds
