Health
The Health tab displays device performance status for managed
devices, and includes their RF domain memberships.
To assess system health:
- The Health tab displays by default.
The Health screen is partitioned into the following fields:
- 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 Type 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
Index 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 RF
Quality field displays an average quality index supporting each RF
domain. The table lists the bottom five (5) RF quality values for 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. The System Security field displays a list of up to five 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.
