High Availability for Application Usage Statistics

How active/passive and active/active high-availability configurations affect where you can view application usage statistics.
When you configure two firewalls as a High Availability (HA) pair, the application usage statistics are local to the firewall that generates the Traffic logs for the application. Where you can view application usage statistics also depends in part on the HA configuration:
  • Active/Passive—The active device generates the application usage statistics. If a passive device has seen no user traffic, then only the active device displays the application usage statistics. If a passive device has seen traffic, then the passive device only displays the application usage statistics from the traffic that it has seen.
    On a failover, the application usage statistics are based only on the Traffic logs generated on the newly active device (the device that was passive before the failover).
  • Active/Active—The device that owns a session generates the Traffic logs for that session, so the application usage statistics for a session are only available on the device that owns the session. If one active device owns a session, the other active device does not display that session’s application usage statistics.
