How do I monitor latency between two nodes in our environment?

Unless I'm getting the wrong end of your question, then so long as you have the specific interface(s) that connect these two nodes together, then you can go to the specific interface summary pages for each and see traffic, etc...

Alternatively you could set up a specific Perf Analysis project, add the distinct interfaces in and whatever metrics you want.

Thank you very much for the response, its much appreciated.

The trouble is that two given sites don't have a link which is exclusive to those two sites. So lets say that we have a regional colo in NYC, which hosts resources for a number of other US sites. If I look at the network utilisation of the colo site in NYC, I'm seeing the collective traffic of all sites which access those resources.

So I'm not sure I can gauge latency between the colo NYC site and say denver. As the link isn't exclusive.

Hope that I am making some sense, I'm a solarwinds person rather than a network engineer

Ahh understood and yes I do follow. In which case you'll only ever get a "sense" of the latency, etc by monitoring specific links.

If you have Netflow and the relevant nodes are configured to send that data to Solarwinds, then you could use that to extract the conversation(s). Other than that, then Adam's suggestion is a potential option depending on the node(s).
