Monitor Trends You can view historical data to help you to analyze traffic patterns and to identify
problems. Data can be displayed in increments of seconds, minutes, hours, or
days.
To view the data in a table, click the Grid Mode button below the area. To display
a chart, click the Chart Mode button. Use the 60s, 1h, 1 d, and 1 w links to
display the data in increments of 60 seconds, 1 hour, 1 day, or 1 week.
To monitor trends, from the Monitor menu, choose Trends.
Table 15 - Trends Graphs
Graph Description
Bandwidth Utilization The Bandwidth Utilization graph indicates the percentage of the available bandwidth that was used. The graph can show
the bandwidth usage patterns over incremental instances in time (by 60 seconds, 60 minutes, 24 hours, or 14 days). This
graph also marks the highest peak reached. The default is 60 seconds.
You can use this data to determine when network usage is high or low.
Packet Error The Packet Error graph shows the percentage of packet errors collected over incremental instances in time (by 60 seconds,
60 minutes, 24 hours, or 14 days). The default is 60 seconds.
Use this graph to audit the affects that connected devices have on the switch performance or the network. For example, if
you suspect that a connected device is sending error packets, you can verify if the data on the graph changes when you
disconnect and reconnect the suspected device.
Port Utilization/Errors The Port Utilization/Errors graph show the usage patterns of a specific port over incremental instances in time
(by 60 seconds, 60 minutes, 24 hours, or 14 days). The default is 60 seconds.
To display the trends for a specific port, choose a port from the Port list.
Use these graphs to observe the performance of a specific port. For example, if a network user is having intermittent
network connectivity, use the Port Utilization graph to observe the traffic patterns on the port to which the user's
personal computer is connected, and use the Port Errors graph to see if the port is receiving or sending error packets.
PoE Utilization For PoE switches, the PoE Utilization graph shows the power that is allocated to the connected devices.
