Hi, I am attempting to setup ganglia for the first time. Having read the
documentation and looked at a couple of examples. I still have
a few queries. Let me explain what I am attempting , what I have
configured and what I see.
What I am attempting.
To configure two clusters.
What I have configured.
1. web front end server, with the following installed;
apache
ganglia-gmetad-3.0.0-1
ganglia-web-3.0.0-1
The gmetad conf file /etc/gmetad.conf contains the following entries;
data_source "linux cluster" 10 localhost:8649
data_source "solaris cluster" 10 localhost:8650
gridname "Leop LSF"
everything else remains as default.
2. client machine. ( Linux box )
ganglia-gmond-3.0.0-1
The gmond conf file /etc/gmond.conf contains the following entries;
cluster {
name = "linux cluster"
}
What I am seeing is;
a number of machines in "unspecified" cluster. How do I blow these away.
I understand that if I either restart all daemons, or else enter
globals {
host_dmax = 3600
}
in the gmond.conf it should take care of this. The thing is some nodes
appear on both lists, ie in linux cluster and unspecified.
The other thing I am seeing for the hosts visible in the "linux cluster"
cluster is that they are showing as down. Yet when I run a
telnet localhost 8649
I see the xml output. I figure I should be able to see the aggragate
data on the head node, ie the one with gmetad and the php web interface
installed. How do I debug this ? I have not gone down the road of
installing the solaris binaries until I have this sorted. Any help
appreciated.
Tks,
-Bob
