This is a followup to the earlier posting where I installed and configured Ganglia to monitor 2 nodes. In this posting I try and add another node(isvpx3) to that setup.
Changed https to http in the /etc/sysconfig/rhn/up2date file:
That helped get rid of the "The SSL certificate failed verification." error, but yum install ganglia still did not go through as shown below.
As the above failed, I went onto to install the Extra Packages for Enterprise Linux (EPEL) rpm as follows
Was able to install ganglia using yum install after that:
Next I install ganglia-gmond using yum.
Edit the /etc/gmond.conf file as follows:
also, change the following in the /etc/gmond.conf
also, change the following in the /etc/gmond.conf
Start the gmond daemon
You can see the Hosts up count has increased by 1. Also you can see the name of the newly added host in the drop down menu for "my servers"

i dont know if this steps will work if you have multiple clusters and one ganglia host.
as i know you will have to mention your new host into the main ganglia host under gmetad.conf
Generally I don't read post on blogs, but I would like to say that this write-up very forced me to take a look at and do so! Your writing taste has been surprised me. Thank you, quite nice article.
