Hi guys, My apologies for another question(*) which seems pretty simple - I've got one machine which serves as the head node for a cluster, and which I don't want to be included in the data gmetad is plotting for me.
.. Now, when I run gmond on the compute nodes, but not on the head node, I don't get ANY statistics, but as soon as I boot up gmond on the head node as well, I get statistics from all of the nodes. Obviously I'm missing something simple here, but how do I get the gmonds on the compute nodes to send their data off to the head node? They are on the same network, except I should point out that the head node has two NICs, each on different networks - is this somehow causing confusion? In short, is there something simple I should specify in gmetad in the head node in order for it to 'find' the gmonds on the cluster, without running one locally? (Currently, it's pretty much a default setup - no real changes to the .conf files. However, that being said, I've tried everything I can think of to get it to work - explicitly saying the data_source is the hostname associated with the IP for the internal, node-based network as well, but to no avail.) Thanks.. if more info is needed, I'll happily write more. Best wishes, - Brian (*) PS. I fixed my problem with the segfaulting binaries - a kernel recompile cured that, but I haven't narrowed down exactly what options caused the error yet. When time permits, I'll get to that.
