The Health screen displays the
overall performance of the managed network (system). This includes device availability,
overall RF quality, resource utilization and network threat perception.
To display the health of the managed
network:
Select the Statistics → System menu from the Web UI.
Select Health from the left-hand side of the UI.
Statistics - System - Health Screen
The Devices table displays the total number
of devices in the
access pointmanaged network. The pie chart is a
proportional view of how many devices are functional and currently online. Green
indicates online devices and red offline devices detected within the managed
network.
The Offline Devices table displays a list
of devices in the controller managed network that are currently offline.
The table displays the number of offline devices within each
impacted RF Domain. Assess whether the configuration of a particular RF Domain is
contributing to an excessive number of offline devices.
The Device Types table displays the kinds
of devices detected within the system. Each device type displays the number currently
online and offline.
Use the RF
Quality table to isolate poorly performing radio
devices within specific controller managed RF Domains. This
information is a starting point to improving the overall quality
of the wireless controller managed network. The RF Quality
area displays the RF Domain performance.
Refer to
the following table for details:
Worst 5
Displays five RF Domains with the lowest
quality indices in the wireless controller managed
network. The value can be interpreted as:
0-50 – Poor Quality
50-75 – Medium Quality
75-100 – Good Quality
RF Domain
Displays the name of the RF Domain wherein
system statistics are polled for the poorly
performing device.
The System
Security table defines a Threat
Level as an integer value indicating a potential
threat to the system. It is an average of the threat indices of
all the RF Domains managed by the access
point.
Threat Level
Displays the threat perception value. This
value can be interpreted as:
0-2 – Low threat level
3-4 – Moderate threat
level
5 – High threat level
RF Domain
Displays the name of the target RF Domain for
which the threat level is displayed.
