To elaborate on my issue, I'm attaching my gmetad.conf file from my
headnode, then the gmond.conf on the headnode, which is the same exact
gmond.conf that I have on my nodes. (perhaps that's where i've gone
wrong?)
If I run gmond on the headnode, it only reports variome.chop.edu in my
web interface, despite gmond running on the nodes. If I change
'localhost' in gmetad to include both localhost and node01 or node02,
then the two nodes appear in my interface, and the variome server is
no longer listed. Strangely, it doesn't matter if I place node01 or
node02 in gmetad.conf, they both cause ganglia to display the two
nodes in the interface.
my understanding is that gmetad need only to list 'localhost', as long
as the nodes point gmond.conf to the same IP that is listed in
udp_recv. I'm probably causing a lot of people to bang their heads on
the table, at the obvious mistakes I'm making, but I'm not seeing
it... Any suggestions are very much appreciated.
GMETAD.CONF:
data_source "Variome" localhost
gridname "Variome"
GMOND.CONF:
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
}
cluster {
name = "variome.chop.edu"
owner = "unspecified"
latlong = "unspecified"
url = "variome.chop.edu"
}
host {
location = "CHOP"
}
udp_send_channel {
mcast_join = 239.2.11.71
port = 8649
}
udp_recv_channel {
mcast_join = 239.2.11.71
port = 8649
bind = 239.2.11.71
}
tcp_accept_channel {
port = 8649
}
