Yes: gmond has two pieces, - one that gathers metrics from the local host and sends them to the network - one that collects metrics from the network Typically, you'd have a bunch of gmond nodes all multicasting their metrics to the same multicast IP and port. Any gmond node listening on that multicast IP and port, that sees these metrics, will collect all of them, and know about all the hosts. However, gmond's collector does *NOT* automatically know about the metrics gathered from its own host. It will see them on the network and collect them just as it collects metrics from any other node. So, make sure you have your network configuration stuff in gmond.conf set up correctly such that it is sending metrics to the same network, IP, and port as it expects to collect them from, and if you think you have it right, watch for traffic on your network and see what's going on. -- Cos ------------------------------------------------------------------------------ Register Now for Creativity and Technology (CaT), June 3rd, NYC.
