Step 5 (Optional) To display statistics and status information for an existing server farm, choose a server farm

Back Inservice This field appears only for host server farms.
Enter the percentage of real servers in the primary server farm that must be active again for the ACE
to place the server farm back into service. Valid entries are integers from 0 to 99. The value in this
field must be greater than or equal the value in the Partial Threshold Percentage field.
Probes In the Available list, choose the probes to use for health monitoring, and click Add. The selected
probes appear in the Selected list.
The redirect server farm probe list contains only configured probes of the type Is Routed, which
means that the ACE routes the probe address according to the ACE internal routing table (see the
“Configuring Health Monitoring for Real Servers” section on page 6-41).
Note You can associate both IPv6 and IPv4 probes to a server farm.
Note The list of Available probes does not display the VM probe type. To choose a VM probe for
monitoring local VM usage, see the Dynamic Workload Scaling field.
To remove probes that you do not want to use for health monitoring, select them in the Selected list,
and then click Remove. The selected probes appear in the Available list.
