hi there list!

I'm trying to find and keep track the status of all oracle nodes in my
network using nvsniffer. I wrote in nvsniffer.conf the following:
isOracle|1521|OracleServers|Oracle|||*
but ... nothing! I talk with the Oracle Admin and he told me that all
servers with oracle have more interfaces and Oracle service is configured
to listen only on a particular address. So I tried to put such an address
instead of * in my nvsniffer.conf (for example 172.16.1.31). running
manually nvsniffer I received:
"unable to find any node(s) matching the node selection criteria
'172.16.1.31'"
The node that has the interface with this IP is named spappcl11m (netview
has it that way in its maps) and this is resolved to 10.16.1.21 while
172.16.1.31 is mapped to spappcl1d.
How can I resolv this problem? Do you have any other ideea?
thanks a lot
