Session Trends Monitor
The Session Trends monitor provides summary and detailed trend information about the number of active sessions within the node selected in the View pane.
 | Note: After a device is discovered, trend data does not appear immediately—it appears only after three polling periods have occurred. |
Scope information: This monitor is available when you select the following nodes or node types in the View pane: The My Network node, switch, The Wireless Network node, wireless domain, wireless cluster, wireless controller, wireless access point, radio, site, building, or floor.

Session Trends
The summary view of the Session Trends monitor displays a line graph of the number of active sessions over time within the node selected in the View pane. The vertical axis is the number of active sessions. 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.
- Display the number of sessions at a polling interval by mousing over the intersection of the horizontal graph line and a vertical polling interval line.
If you are viewing data for a time period longer than one hour, each data point on the graph represents data consolidated from more than one polling period. In this case, the graph shows multiple lines, which are labeled in the legend:
- maxSessionCount—The largest value sampled during the consolidated polling periods.
- avgSessionCount—The average of the values sampled during the consolidated polling periods.
- minSessionCount—The smallest value sampled during the consolidated polling periods.
The area between the maxSessionCount and minSessionCount lines is shaded to indicate the range of values. You can perform the following actions using the graph legend:
- Highlight a line in the graph by mousing over the line’s legend.
- Remove or restore a line by clicking its legend.
Session Trends Details
The Session Details window provides detailed trend information about the number of active sessions 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 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 at a polling interval by mousing over the intersection of the horizontal graph line and a vertical polling interval line.
If you are viewing data for a time period longer than one hour, each data point on the graph represents data consolidated from more than one polling period. In this case, the graph shows multiple lines, which are labeled in the legend:
- maxSessionCount—The largest value sampled during the consolidated polling periods.
- avgSessionCount—The average of the values sampled during the consolidated polling periods.
- minSessionCount—The smallest value sampled during the consolidated polling periods.
The area between the maxSessionCount and minSessionCount lines is shaded to indicate the range of values. You can perform the following actions using the graph legend:
- Highlight a line in the graph by mousing over the line’s legend.
- Remove or restore a line by clicking its legend.
- 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.
