How long does it take for FPolicy show-engine to get connected after enabling a policy

I am having a NetApp 9 filer. I configured FPolicy and enabled the policy. 


But after enabling the policy for almost 25 seconds, fpolicy show-engine command did not return any entries. It was giving me 

There are no entries matching your query.

I am using Ontapi, to perform FPolicy configuration. How many seconds should I wait for the external-engine to get connected?


Thanks a lot for your help!
