You may have a misunderstanding of how gmond and gmetad communicate. Any gmond node that gmetad consults must have the information for all nodes in that cluster. This is either accomplished by using multicast or configuring all the nodes to send their status to a subset of nodes in the cluster and have gmetad query that subset as data_sources. In your simple case you would need have server2 send (create a udp_send_channel) to server3 (with a udp_recv_channel) or vice versa. -- Mark Wagner | [email protected] System Administrator | Intelius Inc. ------------------------------------------------------------------------------ Hi Mark, Both hosts have the same exact gmond.conf using default multicast settings below... /* The host section describes attributes of the host, like the location */ host { location = "unspecified" } /* Feel free to specify as many udp_send_channels as you like. Gmond used to only support having a single channel */ udp_send_channel { #bind_hostname = yes # Highly recommended, soon to be default. # This option tells gmond to use a source address # that resolves to the machine's hostname. Without # this, the metrics may appear to come from any # interface and the DNS names associated with # those IPs will be used to create the RRDs. mcast_join = 239.2.11.71 port = 8649 ttl = 1 } /* You can specify as many udp_recv_channels as you like as well. */ udp_recv_channel { mcast_join = 239.2.11.71 port = 8649 bind = 239.2.11.71 } ------------------------------------------------------------------------------ Learn how Oracle Real Application Clusters (RAC) One Node allows customers to consolidate database storage, standardize their database environment, and, should the need arise, upgrade to a full multi-node Oracle RAC database without downtime or disruption http://p.sf.net/sfu/oracle-sfdevnl _______________________________________________ Ganglia-general mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/ganglia-general
