Changing the multicast ports makes perfect sense, I have no idea why I didn't think of it. I just tried it out and it works perfectly. Thanks Ian!

The way I avoid this is by creating a separate channel for each 'Farm' (cluster). To do this I pick a different multicast port for each cluster. By changing the port, the nodes no longer talk to each other and the clusters contain unique nodes. In 2.5.x syntax you would have two gmond.conf files that had the following values set: -- Farm-A gmond.conf -- name "Farm-A" mcast_port 8649 -- Farm-B gmond.conf -- name "Farm-B" mcast_port 8650 Good luck, Ian Torres, Marcus wrote: Hi All, I'm having a problem where one of my linux nodes is showing up in 2 different farms on the webfrontend. This is because I have Farm-A and Farm-B, one of the nodes on Farm-B just happens to be on the same subnet as one of the machines in Farm-A (lets call this node NODE1B. Due to multicast, the NODE1B picks up my Farm-B node and adds it to the Farm-A. I hope that wasn't too complicated. Now you're probably wondering why it would show up in Farm-B's grid if it is being picked up by multicast on Farm-A. The thing is, I want it to belong to Farm-B on purpose , so in /etc/gmond.conf for the Farm name it belongs to I made it the same as the the other nodes in Farm-B. This is kind of a hack since I'm forcing it to join Farm-B, but in the end, that's where I want it to be. Basically, how do I stop the node in Farm-A from picking up the node in Farm-B via multicast. I don't want a node showing up in 2 different farms on the webfront end. I tried explaining it the best I can, I have a feeling no one knows what I'm talking about though.
