What is a Real Time Chart?
A Real Time Chart consists of 1 to 4 graphs that display statistical data on the
performance of your network devices. These graphs are updated dynamically.
That is, you can monitor the performance of devices and data is displayed and
updated in real time.
The data that is collected is divided into chart types (described below). The chart
types that are available to you depend on the device interface or Data Link
Connection Identifier (DLCI) that you select from the Device Display Area within
the Navigation Wizard.
Chart Type
Description
Analysis
Illustrates burst and end-to-end measurements.
Compression

Congestion
Specifies what in the network may be causing packets not to reach
their destination.
Diagnostics
Tracks the basic errors on a link that affect data movement.
Integrity
Shows how data is able to move over the link.
Summary
Displays all activity on a link.
Throughput
Indicates the flow of data that is able to travel through the network to its
destination.
This chapter describes how to access, view, and manage Real Time Charts. See
Chapter 4,
