Trend

This dashboard displays the aggregate global trend performance and error rates for controllers over time for trends. FortiWLM MEA collects statistics from a controller and stores it in the database. The Trend dashboard provides the data collected for a single controller or up to five controllers. The trends per controller can be edited by selecting the controllers from the Custom Group option on the trend dashboard.

The Trend Dashboard displays the Global Trends (All controllers) in the graphs on the top portion of the window and Trends per controller on the lower portion of the window. Multiple lines are sometimes displayed in the lower set of charts due to multiple controller selection. The trends are plotted for the last 1 to 48 hours by representing up to five controllers at a time. The time period can be modified from 1 to 48 hours by selecting the Trend Interval or by selecting the From and To duration of time.

Click on one of small graphs in the dashboard to view a larger version displayed in the center of the dashboard. Hover the mouse pointer on a graph to view the time and value of that data point.

The following Global Trends and Controller Trends charts are displayed.

Chart

Description

Throughput Throughput represents all controllers' throughput aggregated. This value is determined with the formula TX_unicast_data_bytes + RX_unicast_data_bytes) / time_duration * 8. Fractional values are included in the previous bar. For example, if throughput is 10.5, it is counted in bar 9-10 (assuming bars are 9-10,11-12 and so on).
Stations Total number of stations associated to Network Manager controllers during the time period selected.
Online APs Online APs displays the sum of all online APs on up to 5 controllers.
Offline APs Offline APs displays the sum of all offline APs on up to 5 controllers.
Critical Alarms Critical Alarms represents the aggregate number of all critical alarms on up to 5 controllers.
High Noise Radios The High Noise Radio chart is the aggregate number of radios experiencing noise greater than threshold (-70 dBm). You cannot change thresholds at this time.
High Loss Radios The High Loss Radio chart is the aggregate number of radios experiencing loss greater than the threshold (40%). You cannot change thresholds at this time.

High Loss Stations

Aggregate number of high-loss stations for each ten minute period. High loss is defined as 40%.

Low RSSI Stations

The Low RSSI Stations chart is the aggregate number of stations on all controllers that are experiencing loss greater than the threshold (-80dBm). You cannot change thresholds at this time.

Rogue APs

Rogue APs represents the classification of controllers into ten groups based on number of rogue APs detected on each controller.
