What is Jstatd?
The jstatd command is an RMI server application that monitors for the creation and termination of instrumented Java HotSpot VMs and provides an interface to enable remote monitoring tools to attach to JVMs that are running on the local host. The jstatd server requires an RMI registry on the local host.

How do I connect to a VisualVM remote server?
Connecting to a Remote Host
To add a remote host, right-click the Remote node in the Applications window, choose Add Remote Host and type the host name or IP address in the Add Remote Host dialog box. (You can also specify a display name that will be used to refer to the host when listed under the Remote node.)How do I monitor JMX?
JMX Monitoring is done by querying data from “Managed Beans” (MBeans) that are exposed via a JVM port (JMX console). An MBean represents a resource running inside a JVM and provides data on the configuration and usage of that resource. MBeans are typically grouped into “domains” to denote where resources belong to.

The most common way to enable remote JMX access to your JVM is to specify a TCP/IP port number and some basic security settings when you start the JVM. The security settings commonly include authentication and SSL (Secure Socket Layer). Derby attempts to use the JVM's built-in platform MBean server.
How do I monitor remote JVM using VisualVM?
There are two ways to connect a remote JVM application to VisualVM: Either using jstatd or Java Management Extensions (JMX).
