sure. If you're polling the network nodes by remote poller (the polling is assigned to those pollers), the response time and availability is monitored in it's context. The additional pollers are licensed separately, but you pay just the Core license. Not sure if there's possible to have APE license if your main poller license is not the unlimited one, but that should be easy query for sales. You should be able also to evaluate the Additional poller to check if the oslution will suit your needs. If you're on the NPM 12.0.1, you should be able to find the installer on the Polling Engines page.
