the gmond that receives the message tries to resolve the source address of the incoming packet that it receives. the source address if dependent on which interface that data was sent on (an ifconfig -a will show you the local addresses associated with each interface).
the problem is if your resolver can resolve the ip address on a particular interface (e.g. it can resolve public ip addresses but there are no entries for private ip addresses).

I've installed Ganglia 3.0.0 on a 32 node cluster of XServe G5's with Darwin Kenel 7.8.0 on master node and 7.7.1 on interior nodes. The metrics are much better with version 3.0.0 (which I'm very grateful for) but I have a couple problems I was hopeing someone might have some insight about. Problem 1: When running the configure script I get the following message (gcc version is 3.3): checking net/if.h presence... yes configure: WARNING: net/if.h: present but cannot be compiled configure: WARNING: net/if.h: check for missing prerequisite headers? configure: WARNING: net/if.h: proceeding with the preprocessor's result configure: WARNING: ## ------------------------------------ ## configure: WARNING: ## Report this to [EMAIL PROTECTED] ## configure: WARNING: ## ------------------------------------ ## The error messages in config.log are these: configure:19987: checking net/if.h usability configure:20000: gcc -c -g -O2 conftest.c >&5 In file included from configure:20069: /usr/include/net/if.h:186: error: field `ifru_addr' has incomplete type /usr/include/net/if.h:187: error: field `ifru_dstaddr' has incomplete type /usr/include/net/if.h:188: error: field `ifru_broadaddr' has incomplete type /usr/include/net/if.h:219: error: field `ifra_addr' has incomplete type /usr/include/net/if.h:220: error: field `ifra_broadaddr' has incomplete type /usr/include/net/if.h:221: error: field `ifra_mask' has incomplete type /usr/include/net/if.h:290: error: field `addr' has incomplete type /usr/include/net/if.h:291: error: field `dstaddr' has incomplete type configure:20003: $? = 1 configure: failed program was: | #line 19989 "configure" | /* confdefs.h. */ ... I'm not sure if these errors have any bearing on the other problem I have. Despite the configuration errors, I'm still able to compile and run both gmond and gmetad. -- Problem 2: The gmond daemons do not return the hostname, but rather an IP address. Here's an example from the XML output (telnet localhost 8649): <HOST NAME="192.168.12.220" IP="192.168.12.220" REPORTED="1108749163" TN="19" TMAX="20" DMAX="0" LOCATION="unspecified" GMOND_STARTED="1108747603"> If I switch back to version 2.5.6 then the hostnames appear fine. In any event, the hostnames are resolvable through the /etc/hosts file and a DNS server that serves the cluster.
