Network Statistics
Cisco WAN Manager collects network statistical data on the operation of the network and stores them
in its database. They are available for display on the Cisco WAN Manager console in either tabular form
or as bar charts. Statistics can be a useful source of information for troubleshooting problems that do not
necessarily cause a major or minor alarm indication or for locating intermittent failures that may occur
at random.
The following are the four classes of statistics:
•
Trunk statistics
•
Line statistics
•
Connection statistics
•
Frame Relay port statistics
Most statistics are collected on demand and must be enabled by the system operator. The operator can
set the collection interval, the sampling times, and the number of collection buckets to tailor the statistics
for either long-term network performance evaluation or short term for network troubleshooting.
Table 27-1 lists the statistics categories and the general nature of the statistics collected in each category.
Note this is not a complete list of statistics but merely indicates some of the various conditions
monitored. For a complete listing, refer to the
Cisco WAN Manager User’s Guide
