Chapter 6: Monitoring

This chapter explains the monitoring functions available in RealPlayer Intranet Administrator. The Java Monitor feature in RealPlayer Intranet Administrator continuously monitors real-time activities.

Understanding Java Monitor

Included with RealSystem Administrator is a configurable graph that displays real-time information about the number of clients connected to RealPlayer Intranet Administrator, the resources used, and which files are being accessed.

RealSystem Administrator includes a real-time Java Monitor to show activity on your RealPlayer Intranet Administrator, making network management easy. It shows who is using the RealPlayer Intranet Administrator, when it is most used, and which files are the most requested, as well as other information.

Use feedback from Java Monitor to:

Better respond to customer demand.
Determine peak usage times.
Make more informed business decisions.

Using Java Monitor

As soon as you start Java Monitor, you can immediately view the activity on your RealPlayer Intranet Administrator.

To start Java Monitor:

In RealSystem Administrator, click Monitor. Java Monitor appears. You can make selections from several places in Java Monitor.

Configuring Java Monitor Settings

Java Monitor uses just two variables from RealPlayer Intranet Administrator: Monitor Port and Monitor Password. You do not need to change these values, unless you want to use values that are different from the default settings.

To change Java Monitor settings:

In RealSystem Administrator, click Configure>General Setup>Ports.
In the Monitor Port box, type the port number for the Java Monitor you want to use to connect to RealPlayer Intranet Administrator. The default value for this option is 9090.
Click Apply.
Click Close in the Configuration Change Results window.

Optional Java Monitor Features

There are several ways you can control what Java Monitor displays. This section discusses the commands in the Java Monitor display area and explains their functions.
