Hi Alan,
You are correct - negative numbers say that the poll should have happened that number of seconds ago. There could be several reasons...

Can NetView actually talk SNMP to these devices? Have community names changed? You may simply be asking netmon to do too much too quickly. The samples you gave are about 3.5 minutes behind - are they all similar times? Are there lots more entries? If you have lots of status polling via SNMP then think about increasing the status poll interval and see if your problem goes away. Make sure your Config poll (default 24 hours) hasn't been inadvertantly changed to something far more demanding for netmon.

Cheers,
Jane

I have many entries in my snmpList with negative values. I do not recall
what the negative number means. Thee are about 200 devices. If I recall the
negative number means that netmon is behind in polling. Is this correct? I
am getting many false node down messages.
