I have set a ganglia server to monitor a cluster of 390 nodes in unicast
mode. Gmond goes ideal and nothing is shown on the graphs.
The gmetad server is 172.17.203.43.
Find below the gmond.conf and the gmetad.conf
Gmond.conf
globals {
daemonize = yes
setuid = yes
user = ganglia
debug_level = 0
max_udp_msg_len = 1472
mute = no
deaf = yes
allow_extra_data = yes
host_dmax = 86400 /*secs */
cleanup_threshold = 300 /*secs */
gexec = no
send_metadata_interval = 30 /*secs */
}
/*
* The cluster attributes specified will be used as part of the <CLUSTER>
* tag that will wrap all hosts collected by this instance.
*/
cluster {
name = "cluster"
owner = "unspecified"
latlong = "unspecified"
url = "unspecified"
}
/* 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
host=172.17.203.43
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 = 172.17.203.43
}
/* 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
}
gmetad.conf
data_source "cluster" 20 localhost
