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.
