Eduardo, Interesting suggestions. My thoughts:
- About logging the entries locally, in addition to sending them to the mgmt node (or service node): This seems to make perfect sense for nodes that are installed on their local disk. For diskless nodes, it doesn't seem like the right thing to do, because either it will use up the node's memory, or (in the statelite case if that dir is nfs mounted) it will get sent over the network a second time. - About using TCP instead of UDP: I can see why some would want this, although as you already pointed out, it would use a little more bandwidth. Maybe for both of these options, we could put the code in the syslog postscript, but have it do those things only if you specify parameters to the postscript. (Parameters to postscripts are now supported.) Jarrod, Egan, what are your thoughts about this?

I generally modify the syslog postscript to simply append the forward to the existing syslog.conf. Christian D.

Now that I have the correct file in hands, my thoughts: If I understood correctly, the syslog postscript moves the default configuration to <filename>.XCATORIG and replaces it with a single instruction that forwards every log entry to the Management Node using UDP connection. Now, I have two points: 1) I would like to use TCP (or even RELP) instead of UDP. TCP is more reliable than UDP and RELP is more reliable than TCP (but bandwidth consumption may grow a little). In addition, we should *append* the forward instruction to the config file instead of replacing it. Keeping record of everything locally is important most cases. Are those reasonable thoughts?
