drill down on link with high bandwidth usage and get node

Hi,

Is it possible to drilldown on a link with high bandwidth usage and get the node who's causing this?

regards Marc

Do you have that data somewhere?

All weathermap does is take numbers and turn them into colours. It's up to you where the numbers come from! :-)

You would need something like netflow or sflow data to do this job, typically.
Weathermap 0.98 is out! & QuickTree 1.0. Superlinks is over there now (and built-in to Cacti 1.x).
Some Other Cacti tweaks, including strip-graphs, icons and snmp/netflow stuff.
(Let me know if you have UK DevOps or Network Ops opportunities, too!)

Yeah we have netflow in nfsen, I need somehow to correlate the high bandwidth data with the culprit(s).

OK, then you can set the INFOURL for the link to link to an nfsen query page, if you can figure out what the query is. If that specific device is a Netflow exporter, then the nf records should include the interface name. Otherwise it will be a harder, and more like guessing.
