UNIX® Fault Management: A Guide for System Administration

Collecting Network Performance Data

This section describes some of the tools available for collecting network performance information. Some overlap exists between network performance management and system performance management. For example, a network application may have a low network transmission rate because it isn't getting sufficient CPU time to send its data. Consequently, overlap also exists between the tools used for system and network performance management.

Using RMON and RMON-II Instrumentation

RMON I and RMON II (defined in RFCs 1757 and 2021, respectively) together form a standard for network performance management. Monitors, or probes, are placed on specific LAN segments and then collect data on those segments. Packet statistics ...
