Hi.
This may be a stupid question, but I am experiencing a strange problem in NAV, where only about a third of the links on our core router shows up with any usage, the rest comes up as if there is no traffic there at all. One other switch on the network shows usage towards all other switches, but the rest of the switches on our network shows no usage whatsoever. The easiest way to see this, is when I look at the network map, and find most of the links gray, while some are green. This is a fairly new install (only a few days old,) so I may have missed some of the documentation, but I can't seem to find anything on this problem.
Our goal is, among other things, to monitor for any congestions, so the map could prove useful for those purposes.
Any ideas of what I might be doing wrong?

I don't know if its related, but we have the same issue on our installation. However, it seems to be two separate issues. The Cricket "Bandwidth" graphs are blank on nearly all of our equipment. This is likely because the device itself doesn't support the specific OID (I don't know if it's a Cisco proprietary OID or a universal one) However, I see perfect graphs in switch-ports, router-ports and CPU/Temp - but the network chart thingie will still show grey lines. I've tried to investigate this without getting any further. Personally its not really an important feature, but it would be a nice eyecandy thing to have sorted out.
Best regards,
Vidar S

The question here is: Is the network map the only place you are looking for data when you say it shows no traffic at all?
If you look up the actual router- or switch ports in Cricket, do the traffic graphs appear blank there? The traffic map is known to sometimes have issues with retrieving the correct traffic load numbers.

The data for the bandwidth graphs are taken from Cisco proprietary OIDs, yes.

It seems the problem was also in cricket. I have also had some other issues with this installation, and I am now reinstalling the entire thing. Hopefully, this will help.
