Sure, you can use vR Ops Remote Service monitoring for this. This MP is built in to vR Ops v6.1, so no need to add anything extra.
Basically, deploy an agent per our normal agent install/deployment guidelines. This agent will act as the point from which the remote checks will be run. Once the agent checks in to vR Ops, go in to vR Ops and select "Action > Monitor this Object Remotely". Configure the check you want to run, be it TCP/HTTP or whatever. Once that monitor is created, give vR Ops a couple intervals (5-10) and you'll see the metrics start coming in for that remote check.
