Health

The Health tab displays device performance status for managed devices, and includes their RF domain memberships.

To assess system health:

  1. 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.
