First create a ruleset to detect Node Up/Down traps, then compare the traps
to a collection of server or router.
If device is a router, log the event to a router logfile. If device is a
server, log the event to a server logfile. The logs should contain the
status of device (up/down)
time of status change (day, hours, & minutes)
At the end of the month, run a script or program against the logfiles. The
program or script (Perl in my case) to match the device down with its
corresponding device up. Now subtract the time of the device down trap to
the device up trap. This will give you the length of time the devices was
down. Convert the days and hours to minutes. Match up all the other
down/up trap associated with the same device. Add them all together and you
should have the total number of minutes the device was down for the month.
Now, take the total number of minutes the device was down and subtract by
43200[(24 hours * 60 minutes) * 30 days = # of minutes in a month]. Take
that value and divide by 43200. This will give you the percentage of
availablity for the device.
This method is not 100% accurate, but it had to do for now. I hope someone
else have a better way of doing this.
Hint: This would be a great addition to the next release of NetView.

I would like to (with help from sysUptime) gather information and then
present this to a customer in single number. i.e
Your availability this month on these routers/servers/etc has been 99.7%
Has anyone made something like this? Perhaps someone gcould ive me a few
pointers on how to do this as easy as possible.
