Dear all,
I want to run multi-gmond deamon in one host(no virtual machine) in
order to it is like several hosts.
I have already used library interposition to replace the
socket-related call. And I have already start several deamons successfully.
The "lsof -i | grep gmond" is shown in the following.
"

However, when I run "gstat -a", it shows "

Why? could some one help me? I think there should be 3 hosts here.
