6  <vmid>        Virtual Machine Identifier. A vmid takes the following form:

8                Where <lvmid> is the local vm identifier for the target
9                Java virtual machine, typically a process id; <hostname> is
10                the name of the host running the target Java virtual machine;
11                and <port> is the port number for the rmiregistry on the

13                description of the Virtual Machine Identifier.

15  <interval>    Sampling interval. The following forms are allowed:
16                    <n>["ms"|"s"]
17                Where <n> is an integer and the suffix specifies the units as 
18                milliseconds("ms") or seconds("s"). The default units are "ms".
