This is a small go project to read the current stats provided by a ganglia instance with enabled tcp channel (read from gmond, thus the name gmon).
./gmon REMOTE[:PORT][,REMOTE[:PORT]]
e.g. ./gmon cluster1 cluster2:8922
gmon establishes a tcp connection to the given gmond remote, receives the XML contents and prints the stats as console-friendly table.
