nsight
  
  
    Enables retention of client-history. A
      typical NSight-server enabled, guest access environment may be visited by thousands of unique
      clients on a daily basis. Some of these guest clients are not regular visitors, accessing the
      network infrequently. However, by default, historical data of all guest clients, irrespective
      of their network access frequency, is retained by the NSight server for up to 180 days. This
      results in the database containing thousands if not millions of unique MAC addresses of
      infrequent guest clients. To address this potential problem it is recommended to disable
      client-history retention on a guest WLAN, and use the nsight-policy context to configure a
      separate timer (8 hours by default) specifying the guest client data lifespan in the
      database.

    Parameters
      
      nsight client-history
      
            
              | nsight client-history | Enables retention of client-history in the database. This option is enabled by
                default. | 
          
    
    Examples
      
      On a WLAN, the client-history option is enabled by default. When enabled, all client
        history (including guest-clients) is retained in the NSight server database for 180
        days.
      To disable this option, execute the 
no > nsight > client-history
        command. When disabled, guest client history is retained only for 8 hours, which
        is the default setting defined by the NSight policy applied on the access point (through
        which the guest client accesses the WLAN) or the access point‘s RF Domain. However, the
        default historical data retention duration for regular clients and devices (access point and
        controllers) remains unchanged (180 days) as per the NSight policy
        settings.

Use the NSight policy context to define separate client-history retention time for regular
        clients, devices, and guest clients. For more information, see nsight-policy (global-config-mode).
