Hopefully, Chris, one of the WUG pros will educate us again, but here's my
take based on 5 months experience with it:
800 devices on one map. A new poll on those 800 devices every minute.
Take your polling timeout value into consideration, as well. You didn't
answer as to whether the web view eventually shows the device as coming
back on-line. You said it appears as down, then you can ping it, but then
the device doesn't appear as up again. Is that the case? The device in
the web view never appears green, or does it take a wicked long time to do
so? There is a refresh timer setting in configure-web options for updating
the web view. Mine is set for the default, I think 30 seconds or so. If
your device does eventually show as on-line in the web view, then I'd bet
that your numbers and arrangement are the culprit.
I have about 350 devices in 60+ maps. Every 2.5 minutes WUG polls all the
devices. My polling timeout value of 10 seconds means that if there is a
slow link somewhere, the polling of an individual device will wait 10
seconds for a successful reply. After 10 seconds, the device is reported
as not responding to the poll and WUG moves on to the next device to be
polled. Are all of your devices in close proximity? Mine are all over the
country and in UK, across many different WAN links. If a device is down
for 10 minutes, then a notification goes out (thus 2.5 minutes times a
notification trigger value of 4 missed polls equals 10 minutes). My guess
on how it works is that because I only have an average of 6 devices per
map, as soon as the 6 devices successfully answer the poll, the branch
office subnet icon (ex. NYC) as a whole is reported as up to the
application. While WUG has continued to poll other devices on other maps
during the same polling period of 2.5 minutes, the mentioned NYC branch
office subnet icon is now shown to be up, or on-line, in the web view
during the next refresh (30 seconds) of the web page.
But I could be wrong. Maybe you just have some corrupt data in there
somewhere. How is your poll going out? ICMP? If not, then maybe that is
a factor?? I hope I was at least able to help you better
understandsomething about WUG. Later..........

Well, Chris, I unfortunately inherited the What's UP Gold server and the
person who first implemented did not organize it too well. He created one
map via a hosts file and did not break the devices out in any kind of
order.
I am in the process of creating new maps based on which devices are on
which
Frame Relay host port.
I do believe that 60 seconds is not long enough for 800 devices but haven't
found any information regarding limitations and recommendations. By the
way,
how many times does WUG ping the device during a poll? once, twice, three
times ???
Thanks,
Chris
p.s. Feel free to share your salary. LOL It would be interesting to see
what
people are making in other parts of the country.
