how to know if any service in ambari cluster need to restart by API

the following API will restart all services that restart action is required ( after paramter changes )

but how to know if any service in ambari cluster need to restart by API ( I mean just to check if restart is needed without to perform restart ? )

# curl -iv -u admin:admin -H "X-Requested-By: ambari" -X POST -d '{"RequestInfo":{"command":"RESTART","context":"Restart all required services","operation_level":"host_component"},"Requests/resource_filters":[{"hosts_predicate":"HostRoles/stale_configs=true"}]}' http://$AMBARI_SERVER:8080/api/v1/clusters/$CLUSTER_NAME/reques

Following should list all the components that has stale config, and need to be restaretd to get the config changes reflected.

# curl -i --user admin:admin -i -H 'X-Requested-By: ambari' -X GET  http://localhost:8080/api/v1/clusters/Sandbox/host_components?HostRoles/stale_configs=true



Here please replace the following:


1. "localhost" : with the Ambari FQDN

2. 8080 : with ambari port.

3. Sandbox : With cluster Name
