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

Question

We have an environment with two pollers, polling numerous nodes within our environment. 
 If I click on a given node, I can see stats for response time, packet loss, ie latency but this is recording the latency between the poller and the target node. 
 How would I capture and monitor the latency between two nodes? So between node a and node b.

Remote Ping using any Network Device Maybe this is of use? kpmarcin made a great video tutorial on how to set this up. 
 
 Alternatively check this out Remote TCP Check

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.

You've got some options If they send traffic to each other and you've got agents, you can enable packet scanning stuff for this and get auto-mapping, it's heavy though. 
 You can promote an agent to a mini-poller and monitor one box from the other like that if you're on licensing that allows it If you've got SAM you could put a little script on to check the other one 
 If one or more of these devices is cisco you might be able to use IPSLA with VNQM 
 Probably a few other choices around
