Thanks for the response Bernard!

 

I guess I didn't think that I could only put 1 node in the data_source line
because how does it know to go and collect the information from the other
nodes?  Does it just scan the subnet looking for any machine running gmond?
Every one of my nodes has the exact same gmond.conf file on it with the name
of my cluster in it.  Is that how it knows?

 

Thanks for asking about the graphs... Thanks to everyone's pointers, I
learned that I had listed the path to the RRDtool directory, but hadn't put
the executable name into the path.  After I changed that it all started
working... ;)  Ganglia is really awesome!

If you only have one cluster, you only need one data_source (think of the
data_source as the headnode of your cluster, if you will).

 

So you just need one entry for data_source - you can put more than one node
in the data_source entry for redundancy purposes.

 

So I take it you can see your graph now and the previous thread you posted
is dead?

 

Cheers,

 

Bernard

Subject: [Ganglia-general] All my nodes listed as clusters

I have a silly question, as usual...

 

When I bring up the view of my cluster, it comes up as a Grid... so it
.looks like this:

 

Grid > MyCluster > Choose a Node

 

I'm guessing that's because in my gmetad.conf file I have every node in my
cluster listed as:

 

data_source "N1" 60 192.168.3.2:8649

data_source "N2" 60 192.168.3.3:8649

 

I'm sure that I'm listing them wrong because Ganglia thinks that each node
is its own cluster.  My question is how do I make them appear like one unit
as I see in the demo pages?   Do I add them all to one data_source line?

 

On a side question, is it normal for my head node to always be in the red?
It looks like it's only using about 8% CPU, but it's always red or orange.
