How can I find which policy rules are being used?

You are dealing with a large installed policy for a ProxySG that has been in production for several years. Many policy gestures have been added over the years by different admininstrators and the resulting policy is complex. You want to simplify their policy by deleting unneeded policy or by consolidating existing rules.

The following is an example of a standard visual policy configuration: 

That policy appears as follows on the Policy Coverage page:

In the example above, the number on the left indicates the number of times that rule matched a user request.  The number on the right, in parentheses indicates the number of times the condition in the rule has matched a user request  The values that appear on this page have been gathered since the last time policy, (Visual, Local, or Central) was installed, or  since the proxy was last restarted.  With this information, you can make informed decisions regarding which rules to delete and which rules or objects can be combined to optimize the existing policy.  

Notes:

• This function is enabled by default and cannot be disabled.  Proxy Resources do not increase significantly as a result.
• The statistics gathered are not persistent across reboots or policy installations.  Each time either of these functions are performed, the Policy Coverage counters are reset to zero.
• Objects that are managed in Visual policy appear below all rules in a 'definitions' section.  When a rule containing one of these policy definitions matches a user request, all references to that definition increment in every place it appears in policy.  
• Policy objects that consist of lists in a combined source or destination object report that a match was identified, but only on the whole object.  The specific element in the combined object will not be identified uniquely.
