EP-11 Integrate EventTable with Eagle Query Engine

@from(eventtable = "eagle", metric = "hadoop.jmx.metric", query = "GenericMetricService[@site == \"sandbox\"]{*}", host = "localhost", port = "9090")
define table CPUMetricTable(site string, component string, host string, timestamp long, value double);

@from(eventtable = "eagle", metric = "hadoop.jmx.metric.max")
define table CPUMetricAggTable(site string, component string, host string, timestamp long, value double);
from CPUMetricTable[site == "sandbox" and timestamp > CURRENT_TIME - 0.5h and timestamp < CURRENT_TIME] 
select max(value) as value, component, max(timestamp) as timestamp "hadoop.jmx.metric.max" as metric, groupby component insert into MetricTable;

define table EagleService (query string, metricName string, pageSize int)
from EagleService[metricName == "hadoop.namenode.capacityusage" and query == "GenericMetricService[@site = \"sandbox\"]{*}" and pageSize == 1000] insert into GenericMetricService;
