To run application discovery every 30 minutes, you must provide all the required privileges. However, if you have access to the following table, you can add the data source in vRealize Network Insight Cloud and VALIDATE:

APIs Table Permission Type
/stats.do -- Required
/api/now/v1/cimodel/cmdb_ci/fullclasshierarchy -- Required
/api/now/v2/table/cmdb_rel_type cmdb_rel_type Required
/api/now/v2/table/cmdb_ci cmdb_ci Required
/api/now/v2/table/cmdb_ci_service_discovered cmdb_ci_service_discovered Required
/api/now/v2/table/cmdb_rel_ci cmdb_rel_ci Required

vRealize Network Insight Cloud validates the required privileges and shows any missing privileges as an error. You can check the missing privileges, and then get access to the missing privileges and VALIDATE again.
