Question on Using OS Watcher and private.net to Monitor Private Network

Hello:

This is Red Hat 5.  I've started OS Watcher on all three nodes of an 11.2.0.2 RAC Cluster.  The instructions recommend we create a private.net file to monitor the cluster's private network, and I have some questions:

OSW comes with Exampleprivate.net.  Here's the Linux example in the file:
#Linux Example
######################################################################
echo "zzz ***"`date`
traceroute -r -F node1
traceroute -r -F node2

My questions:

1.  Should the private.net files all be identical?  Each referencing all three nodes in the cluster even itself?

2.  Should the node name be the interconnect name?

Thank you,

Laura Sallwasser
