we are looking for ways to retrieve a subset of monitoring policies of same PolicyType(derived from onap.policies.monitoring).

Something like below:

{

  "ONAPName": "DCAE",

  "ONAPComponent": "PolicyHandler",

  "ONAPInstance": "622431a4-9dea-4eae-b443-3b2164639c64",

  "action": "configure",

  "resource": 

{       "policy-id": "onap.policies.monitoring.nsas-fbb-asam-pref.test.*"   }

}

 

Looking at the policy xml <Target>, it seems it is “string-equal”. Guess we are looking for it to be “string-regexp-match”.
