Alternative Ganglia interfaces

According to the ganglia readme aidle is "Percent of time since boot idle CPU". And it says this is only available for Linux.

My server with the web frontend and gmetad has gmetad.conf with one gridname, plus one data_source entry for each cluster. Each data_source draws from one or more systems in the cluster:

gridname "The Grid"
data_source "Infrastructure" ihost1 ihost2 ...
data_source "Compute Nodes" chost1 chost2 ...
data_source "Workstations" work1 work2 ...

Each host registers itself into a particular cluster, and onto a cluster-specific multicast address in its gmond.conf:

cluster {
  name = "Infrastructure"
}
udp_send_channel {
  mcast_join = 239.2.11.72
  port = 8649
}
udp_recv_channel {
  mcast_join = 239.2.11.72
  port = 8649
  bind = 239.2.11.72
}
tcp_accept_channel {
  port = 8649
}
