We use an event rule to catch all node down and node up events
A netview node down events rule calls a shell script which pings the device's
IP address ($NVA in the shell) 3 times to make sure the node down is genuine,
(as at times timeouts cause erroneous node downs). If the node down is genuine,
we touch a file called $NVA in /var/tmp/netview and allow the event to forward
(in this case to TEC)
A node up event calls a script which looks for /var/tmp/netview/$NVA. If the
file exists, it is deleted and the node event forwarded.
It may seem clandestine but it's the only way we've worked out of getting rid of
erroneous node down events. Also, the nodes we monitor we' don't own the
routers so can get SNMP traps from them.

Subject: How can I threshold Node_Down events ?
Hi ,
I must have surely missed something here , but I cannot work out how
to tell Netview not to send Node_Down events until a threshold (time) has
been met.
My customer wants Netview to only send a Node_Down alert when the node has
node responded to 2 or 3 ping attempts.
Since there is only on Node_Down event generated, I can't use a ruleset to
correlate the events together and seta threshold.
Anyone know of a simply way to do this ?
Mark :-)
