Fortinet FortiWAN - Session; Memory; WAN Link State; Peer Information

Device Status Reports
Session
The line chart in Session panel displays the distribution of sessions amount that FortiWAN processed over the past
one hour. The horizontal (x) axis is graduated in minutes, and the vertical (y) axis is graduated in 1's to indicate the
session amount. Moving the mouse to any point of the distribution will display the exact session amount generated at
the time. Moving the mouse over the line chart and clicking it will redirect you to the Session page (See "Session").
The bar chart aside the distribution displays the percentage of the sessions amount generated in the past five minutes.
The concurrent session capability (denominator) used to calculate the percentage depends on your FortiWAN model.
50% and 80% are the two waterlines used in the bar chart to alert administrators to the exceedance. The bar is marked
with green if the percentage of session amount is less than 50%, with orange if it is between 50% an 80%, and with red
if it exceeds 80%.
CPU
The line chart in CPU panel displays the distribution of FortiWAN's CPU usage over the past one hour. The horizontal
(x) axis is graduated in minutes, and the vertical (y) axis is graduated in % to indicate the CPU usage. Moving the
mouse to any point of the distribution will display the exact percentage of CPU used at the time. Moving the mouse
over the line chart and clicking it will redirect you to the CPU page (See "CPU").
The bar chart aside the distribution displays the percentage of CPU usage in the past five minutes. 50% and 80% are
the two waterlines used in the bar chart to alert administrators to the exceedance. The bar is marked with green if the
CPU usage is less than 50%, with orange if it is between 50% an 80%, and with red if it exceeds 80%.
Memory
The line chart in Memory panel displays the distribution of FortiWAN's memory usage over the past one hour. The
horizontal (x) axis is graduated in minutes, and the vertical (y) axis is graduated in % to indicate the memory usage.
Moving the mouse to any point of the distribution will display the exact memory usage at the time.
The bar chart aside the distribution displays the percentage of memory usage in the past five minutes. 50% and 80%
are the two waterlines used in the bar chart to alert administrators to the exceedance. The bar is marked with green if
the memory usage is less than 50%, with orange if it is between 50% an 80%, and with red if it exceeds 80%.
WAN Link State
The WAN Link State panel displays the state of every FortiWAN's WAN link. The number of WAN links displayed here
varies depending on the model of the FortiWAN unit. Taking FortiWAN 200B for example, it supports 25 WAN link
connections in maximum (See "WAN link and WAN port"). Each WAN link is color-coded to indicate its state.
OK (Green) : The WAN link is configured, enabled and connecting for data transmission.
Backup Line (Blue) :
The WAN link is sat as a backup line (See "Backup Line Setting").
Failed (Red) : The WAN link is configured and enabled, but disconnected.
Disabled (Black) : The WAN link is not active (probably configured or not).
Peer Information
Peer information displays the state of slave unit for a HAdeployment (See "FortiWAN in HA (High Availability)
Mode").
