Comparing CPU Activity on Both Appliances
As soon as Active/Active UTM is enabled on the Stateful HA pair, you can observe a change in
CPU utilization on both appliances. CPU activity goes down on the active unit, and goes up on
the idle unit.
To view and compare CPU activity:
Step 1 In two browser windows, log into the Monitoring IP address of each unit, active and idle. For
information about configuring HA Monitoring, including individual IP addresses, see the
SonicOS Enhanced Administrator’s Guide.
Step 2 Navigate to the System > Diagnostics page in both SonicOS management interfaces.
Step 3 On both appliances, select Multi-Core Monitor from the Diagnostic Tool drop-down list. The
active unit is displayed below with the real-time Multi-Core Utilization graph showing an
immediate drop in CPU activity.
