What is
Performance
Monitoring?
Performance monitoring allows you to assess the caching and system
performance of the Webcache via a series of easy-to-understand MRTG
(Multi Router Traffic Grapher) graphs. The Caching Performance graphs
show the bandwidth savings, hit/miss rate, request rate, response time
and throughput for the Webcache. You can use them to find out quickly
and accurately how the Webcache is performing and how much value it
is providing to your network.
The System Performance and I/O Performance graphs show more detailed
information which is intended for use by your System Administrator and
3Com support personnel.
Performance monitoring is always enabled; you cannot turn it off.
Caching
