I don't know if VisualVM integrates with Eclipse, but it comes with the JDK, so you have it installed and can run it from the command line (or maybe there are scripts that run it, I don't recall how that works). On Windows there's probably something to double-click to start it.
But before you do that you need to enable JMX via RMI for the server; have you done that? That has nothing to do with VisualVM, and is described in
https://docs.oracle.com/javase/8/docs/technotes/guides/management/toc.html, particularly section 2 (be sure to follow all the steps for local and remote access).
