I have just installed Ganglia-3.0.5. Configured without gexec on both machines and with gmetad on one, but not the other. I am able to start gmond and gmetad with no errors. But I am having problems on one of my machines with gmond.
I'm far from an expert and would appreciate a pointer or two. I've searched the mail archives, read the gmond man-page, and Googled the ARPANet, but haven't found anything except this posting http://www.mail-archive.com/[email protected]/msg02601.html. The poster had an error in his conf file, but didn't post what the error was. Below is what I believe to be the pertinent information. But if there is more that is needed, I will post it. Issuing gstat on the head node gives the following: CLUSTER INFORMATION Name: clusterfsck Hosts: 1 Gexec Hosts: 0 Dead Hosts: 0 Localtime: Sat Oct 27 16:34:15 2007 There are no hosts running gexec at this time When I gstat -i 172.16.1.101 from the head node, I get the following and the gmond daemon is killed on 172.16.1.101. gexec_cluster() XML_ParseBuffer() error at line 51: no element found Unable to get hostlist from 172.16.1.101 8649! SSHing into 172.16.1.101 and issuing a gstat gives the same error and kills the gmond daemon. gexec_cluster() XML_ParseBuffer() error at line 51: no element found Unable to get hostlist from localhost 8649! I am using essentially the default configuration on both machines as created by: gmond --default-config > /etc/gmond.conf. <SNIP> /* This configuration is as close to 2.5.x default behavior as possible The values closely match ./gmond/metric.h definitions in 2.5.x */ globals { daemonize = yes setuid = no user = nobody debug_level = 0 max_udp_msg_len = 1472 mute = no deaf = no host_dmax = 0 /*secs */ cleanup_threshold = 300 /*secs */ gexec = no } /* If a cluster attribute is specified, then all gmond hosts are wrapped inside * of a <CLUSTER> tag. If you do not specify a cluster tag, then all <HOSTS> will * NOT be wrapped inside of a <CLUSTER> tag. */ cluster { name = "clusterfsck" owner = "The ReliaFree Project" latlong = "unspecified" url = "http://reliafree.sourceforge.net"; } /* 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 { 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 } /* You can specify as many tcp_accept_channels as you like to share an xml description of the state of the cluster */ tcp_accept_channel { port = 8649 } </SNIP> TIA, Andrew -- Andrew "Weibullguy" Rowland Reliability & Safety Engineer [EMAIL PROTECTED] http://webpages.charter.net/weibullguy http://reliafree.sourceforge.net
