Data is collected at each 60-second system refresh. For a graph that shows
per-port patterns over incremental instances in time (by 60 seconds, 60 minutes,
24 hours, or 14 days), see the
“Per-Port Utilization and Per-Port Errors Graphs”
section on page 4-16 . For details on the specific port errors detected on each port,
see the “Check the Port Statistics” section on page 4-18 .
Check the Trends Graphs
Use the Trends window ( Figure 4-5 ) to display the historical trends graphs. Use
these graphs to display the switch bandwidth, the port usage, and the percentage
of packet errors detected by the switch. You can display the data in increments of
seconds, minutes, hours, and days. The granularity of these graphs can help you
to analyze traffic patterns and to identify problems with the switch and individual
ports.
Tip If you are using the trends graphs to monitor the switch status over time, do not
end your device manager session. Redisplaying the device manager clears the data
from the PoE graph.
To display the Trends window, choose Monitor > Trends. You also can click the
View Trends link from Dashboard.
The Trends window displays these graphs:
