i trying average cpu usage ec2s in specific region. tried following:
- request 1 instance statistics per request, works slow.
- i tried remove dimensions request got empty response, although cli returns instances available (statistics 35 instances on span of 24 hours).
i tried set 10 dimensions per request got exception:

code:
private list<datapoint> monitorinstance(amazoncloudwatchclient cloudwatchclient, list<dimension> dimensions) { list<datapoint> datapoints = new arraylist<>(); try { int dimensionslastindex = 0; (int dimensionsindex = 0; dimensionsindex < dimensions.size(); dimensionsindex = dimensionslastindex + 1) { dimensionslastindex = (dimensionsindex + 10) <= dimensions.size() ? dimensionsindex + 9 : dimensions.size() - 1; long offsetinmilliseconds = 1000 * 60 * 60 * 24; getmetricstatisticsrequest request = new getmetricstatisticsrequest() .withstarttime(new date(new date().gettime() - offsetinmilliseconds)) .withnamespace("aws/ec2") .withperiod(60 * 60) .withdimensions(dimensions.sublist(dimensionsindex, dimensionslastindex)) .withmetricname("cpuutilization") .withstatistics("average") .withendtime(new date()); getmetricstatisticsresult getmetricstatisticsresult = cloudwatchclient.getmetricstatistics(request); datapoints.addall(getmetricstatisticsresult.getdatapoints()); } return datapoints; } catch (amazonserviceexception e) { error(e.getmessage(), stacktracetostring(e)); } return new arraylist<>(); } although want fix exception, wonder if there simple way stats instances in 1 request.
