Those entries are from demandpolls, I think (the d ). That will
generate an event, I believe.

If you unmanage/manage a node, you will get an Up event (if it is up).
Could that be it? If you issue the 'event' command, you will get a
Node Up event. Anyone testing anything?

Some clarification: you said the node up events were coming from
an AIX MLM. Are you sure? Generally the up/down events from the MLM
are for interfaces, and they are set to Don't Log or Display. If you
change that in Event Customization, you will see that you get interface
up/down events from the MLM, and netview in turn generates its own
interface up/down event to make it appear that netmon actually did the
pinging. Then, as James said, you may or may not get a Node up/down/marginal
event - from netview, (not from MLM).

The traps that MLM sends to the Netview server are logged on the MLM
box (under /var/etc/smmlm/log, I think). If you stop/start netmon, you
will notice a flood of up/down interface traps from the MLM as it makes
sure that Netview has the latest status. This is normal.

One of the things fixed in the e-fix for MLM available from support is
superfluous traps. So make sure you have on the MLM from the 5.1.1 CD,
then add that patch.

That's all I know...

Cordially,

I was just looking at the trapd.log and noticed them (this goes back to
the mlm node up/down event)
