Hmm... I can understand the problem clearing when you restart netmon. That
would probably be the equivalent of doing an xnmsnmpconf -clearCache.
So might that have something to do with redirects? If the Netview is on
AIX,
you might check the value of 'no -a | grep ipignoreredirects'. If it is 0,
try
setting it to 1. When the problem occurs, does the ip address listed in
'xnmsnmpconf -resolve <selection name>' change from the good address
to the bad address? I don't know what any of this means, it is just my
voodoo approach to problem determination.....

Cordially,

I would like to know how you resolved the failing SNMP status poll issue. I
am monitoring a hosting environment in which most servers have more than
one address, but the NetView server only has routes and (filter) permission
to specific interfaces. I am using SNMP status polling and I am not using
DNS for name resolution. Instead, I place a single hostname entry for the
accessible address in /etc/hosts. NetView discovers and polls most hosts
correctly. Occasionally, and only for certain servers, NetView starts using
one of the unreachable addresses for SNMP status polling. If I recycle
netmon, NetView starts using the correct address again. I have been unable
to determine the circumstances under which the change takes place.
