Hello, I've set up a AMS API call to retrieve Yarn matrix on a minute basis. I tried to add startTime/endTime in my query. Even though I found the metrics returned are not reflecting the latest time stamp, and data is kind of stale. Is there a way I can configure my query so that it can always catch the latest state of the metrics? Example of my tests: curl 'http://myhost:6188/ws/v1/timeline/metrics?metricNames=[metricsname]&appId=resourcemanager&startTime=1486410484&endTime=1486410784&precision=SECONDS' In the return below, I want to see at least the endTime epoch or endTime - 1min epoch, but sometimes it can't get this far. {u'metrics': [{u'metrics': {u'1486410630000': 0.0, u'1486410570000': 0.0, u'1486410540000': 0.0, u'1486410600000': 0.0, u'1486410510000': 0.0}, u'timestamp': 1486410510000, u'appid': u'resourcemanager', u'starttime': 1486410510000, u'metricname': u'metricsname'}]} Thanks for the help! ...
