-h,--hostlistHOSTS
Specify the lists of diod servers that dtop monitors. Multiple hosts may be separated by commas,
and host ranges may be included in the list, e.g. x[1-3,42] is equivalent to x1,x2,x3,x42. By
default, dtop monitors localhost. Note that dtop uses the "ctl" synthetic file system. "ctl"
must be explicitly exported.
-P,--poll-periodSEC
Set the polling period. SEC may be a floating point number. The default is 1 second.
-p,--portPORT
Specify the server port number for all monitored servers (default 564).
