Hi all, thanks for heads up, we're working to bring this back to SmartConsole, stay tuned...
But rulebase analysis and cleanup can be done today. we have awesome tool called PolicyCleanUp which allows automatic cleanup of your policy based on hits count.
The tool runs on a policy and a domain that you named. If a rule was not hit for the number of days that you configured, the rule is a candidate to be disabled.
If a rule is disabled for the number of days that you configured, the rule is a candidate to be deleted.
You can adjust the code according to your organization’s policy / needs. This tool can be executed on Management Server / Multi-Domain servers of version of R80.10 and up.
