The Health tab
displays performance status for managed devices, and includes their RF domain
memberships.
To assess system health:
Go to
Dashboard → Summary → System.
The overall system Health tab
displays by default.
System Dashboard - Health Tab
The system
health screen is partitioned into the following:
The Devices
field displays a ratio of offline versus online devices within the
system. The information is displayed in pie chart format to illustrate
device support ratios.
The Device Types
field displays a numerical representation of the different
controller, service platform and access point models in the current
system. Their online and offline device connections are also displayed.
Does this device distribution adequately support the number and types of
access point radios and their client load requirements.
The Offline
Devices field displays a table of supported RF domains
within the system, with each RF domain listing the number offline
devices within that RF domain. Listed RF domains display as individual
links that can be selected to RF domain information in greater
detail.
The RF Quality
field displays RF quality per RF domain. It is a measure of the overall
effectiveness of the RF environment displayed in percentage. It is a
function of the connect rate in both directions, retry rate and error
rate.
The table lists the bottom five (5) RF quality values for each
RF domains. Listed RF domains display as individual links that can
be selected to RF domain information in greater detail. Use this
diagnostic information to determine what measures can be taken to
improve radio performance in respect to wireless client load and the
radio bands supported.
The quality is measured as:
0-20 - Very
poor quality
20-40 - Poor
quality
40-60 -
Average quality
60-100 - Good
quality
The System
Security field displays RF intrusion prevention stats and
their associated threat level. The greater the number of unauthorized
devices, the greater the associated threat level. It also displays a
list of up to five (5) RF domains in relation to the number of
associated wireless clients. The RF domains appear as links that can be
selected to display RF domain information in greater detail.
