----------------------------------
Hi, Brian
I tested it on my cluster,which has ganglia 3.1.1 installed.I add a little code
simply based on your patch:
+ String GroupName = name.substring(0,name.lastIndexOf("."))
. . . . . .
xdr_int(dmax); // dmax, the maximum data value
//xdr_string(""); // Empty extra_value field for Ganglia 3.1.
+ xdr_int(1); //this means Num Of the Element follow by
+ xdr_string("GROUP");
+ xdr_string(GroupName);
for (SocketAddress socketAddress : metricsServers) {
DatagramPacket packet
And it seems OK.
> Current Ganglia metrics implementation is incompatible with Ganglia 3.1
