Hi I am new to Ganglia.....I would like to know the steps that you followed for breaking up the hosts into different clusters. It would be helpful if it is explained with your configuration.
Thanks & Regards, Aravindh Phone: 28520408-1053 | Mobile: 9986017606 ________________________________ From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Ian Bonnycastle Sent: Monday, October 23, 2006 10:18 PM To: Ian Cunningham Cc: [email protected] Subject: Re: [Ganglia-general] Cluster under Grid issues I think I actually figured it out. I had the udp_send_channel and the udp_recv_channel settings mixed between the two clusters, so they were getting "cross traffic" and mixing incorrectly. Setting all the values different for each cluster made it work perfectly.

Make sure you've added a new line in the gmetad.conf for the new cluster. You can test that the new cluster only sees the two nodes by doing a netcat `nc` on the tcp port on one of the two nodes, ex `nc node2 8649` Good Luck, Ian C.

Before, all hosts were in one cluster, and now I'm trying to break out the various hosts into different clusters. Originally, they all had the same multicast configuration, probably from the same --default_config output on gmond. Now, I've modified two hosts to be in a different cluster, and changed the udp_send_channel mcast_join IP address as well as the cluster { name } parameter. Even after that, both gstat and the PHP web pages insist there is still one cluster, and the two systems I've moved to the new cluster show up as "down". I'm really confused about why the gmetad on the PHP web server isn't picking up the new multicasts, and why the gmond's on the systems I've changed over still see multicast traffic from the other nodes which are on a different multicast IP. I've restarted the gmond and gmetad on both sets of hosts multiple times with no success, and even removed (backed up) the rrds directory on the PHP server multiple times. Can anyone help with this conundrum?
