Dear Prof. Bernard Li,
    Thank you for your help. I have tried it but still have some problems,
let's give details as following:
    
    Suppose we have 32 nodes which IP are within 202.38.192.[101-132],
ganglia web interface is installed at 202.38.192.1, we want to divide it
into two clusters: "cluster A" is 202.38.192.[101-116], "cluster B" is
202.38.192.[117-132]. i.e. there are some rows in gmetad.conf like this:
data_source "cluster A" 202.38.192.101:8649 202.38.192.102:8649
data_source "cluster B" 202.38.192.117:8650 202.38.192.118:8650
 
    We do not change "cluster A" config file gmond.conf, i.e, "cluster A"
always be displayed normally, now if we change "cluster B" gmond.conf file
xml_port=8650, then we can see "cluster A" and "cluster B" but both of them
contain all 32 nodes; if we only change "cluster B" mcast_port=8650 then
"cluster B" will not be displayed, "cluster A" reporting there are 16 nodes
down and 16 nodes up.
    Next we should try what? 
    Thank you in advance.
 
With Best Regards
Yours

configure gmeta listening on many logic clusters which have same subnet?

 Hi:
 
 I believe you should actually be changing the mcast_port, not the
 xml_port.  Try doing that and then re-start all your daemons (gmetad,
 gmond) and you should be able to see them as separate datasources.
 
 BTW, I assume that you have listed them as different datasources in your
 gmetad.conf as well?
 
 Cheers,
 
 Bernard
