Hi, I am talking about REST APIs at this page :- https://samza.apache.org/learn/documentation/0.10/jobs/web-ui-rest-api.html
How can I execute following rest calls :- /metrics HahsMap that represents metrics for every 60 seconds. /task-context HashMap that provides information about task context including task name and task ID. /am HashMap that represents information about containers and status. /config HashMap that represents the config.
