A DISTRIBUTED AGGREGATION OF REAL-TIME METRICS FOR LARGE SCALE DISTRIBUTED SYSTEMS

摘要

In one embodiment, a metric collection system may collect application metrics across multiple data centers in specific time intervals. A local collection point may establish an absolute reference time for a local data center. The local collection point may determine a source reporting interval for an application based on the absolute reference time. The local collection point 108 may receive a source metric report for the application based on the source reporting interval.
