System Health

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

To assess system health:

1. Go to Dashboard → Summary → System.

The Health tab displays by default.

System Dashboard - Health Tab

The Health screen has 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 Types field displays a numerical representation of the controllers, service platforms and access points models in the current system. You can also see the online and offline device connections and determine if the current deployment adequately supports the number and types of access point radios and their client load requirements.
• The Offline Devices field lists supported RF Domains within the system, with each RF domain listing the number of offline devices. Click each RF Domain for a granular view of RF Domain information.
• The RF Quality field displays RF quality per RF Domain. RF quality is a function of the connect rate in both directions, retry rate and error rate. It is an indication of the overall effectiveness of the RF environment displayed in percentage.

  The table lists the bottom five (5) RF quality values for RF domains. Click each RF Domain for a granular view of RF Domain information. 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.
