Accessing the Statistics, Timer Statistics, Summary Statistics, and Performance Graph windows;
statistics defined; using the Total and Delta radio buttons; setting the Timer Statistics time interval;
configuring the performance graphs
The statistical information collected and stored by your IRM2 provides you with
detailed information about how much traffic your network (or a segment thereof)
is experiencing, including the sizes and types of packets that make up that traffic,
and how much of that traffic comprises packets which have been badly formed or
somehow mangled in transmission. These statistics can give you a good overall
sense of the usage your network, or network segment, is experiencing.
To help you better understand and track the traffic your network is handling,
NetSight Element Manager’s main provides you with a variety of statistical
information presented in four different formats: Statistics, Timer Statistics,
Summary Statistics, and Performance Graphs.
Statistics
At the Statistics windows, you can view accumulated statistics and error
breakdowns for the device as a whole and for each individual board and/or port.
A pie chart graphically depicts these statistics for quick visual reference.
Statistics displayed in these windows include:
• Active Users
• Bytes
• Broadcasts
• Packets
