Session Trends Monitor
The Session Trends monitor provides summary and detailed trend information about the number of active sessions and users within the node selected in the View pane.
After a device is discovered, trend data does not appear immediately—it appears only after three polling periods have occurred.
Session Trends
The summary view of the Session Trends monitor displays a line graph of the number of active sessions and users over time within the node selected in the View pane. The vertical axis is the number of active sessions or users. The horizontal axis shows the polling interval times.
You can perform the following actions on the line graph:
Change the time period over which to display the trend data by selecting a time period from the list in the upper right corner.
Select which SSID to monitor from the Choose SSID list.
Select which VLAN to monitor from the Choose VLAN list. This option appears only when you have selected a switch in the View pane.
Display the number of sessions or users at a polling interval by mousing over the plotted data point.
Highlight a line in the graph by mousing over the line’s legend.
Remove or restore a line by clicking its legend.
Because data points plotted against the x-axis can represent data consolidated from multiple polling periods, three lines are plotted for session count and for user count: the maximum, minimum, and average counts that occurred during the consolidated polling periods.
Session Details
The Session Details window provides detailed trend information about the number of active sessions and users within the current node selected in the View pane. It contains these panes:
The top pane contains a line graph of the number of active sessions and users over time within the node selected in the View pane.
You can perform the following actions on the line graph:
Change the time period over which to display the trend data by selecting a time period from the list in the upper right corner.
Display the number of sessions or users at a polling interval by mousing over the plotted data point.
Highlight a line in the graph by mousing over the line’s legend.
Remove or restore a line by clicking its legend.
Because data points plotted against the x-axis can represent data consolidated from multiple polling periods, three lines are plotted for both session count and user count: the maximum, minimum, and average session and user counts that occurred during the consolidated polling periods.
The bottom pane contains a table with detailed information about the active sessions.
The following table describes the columns that appear in current session details tables.
