Distributed metric data time rollup in real-time

A method for distributed consistent hash backed time rollup of performance metric data, the method including:

• receiving, at a plurality of collectors, time series metrics data for a plurality of performance metrics from one or more agents instrumented into monitored applications;
• aggregating, at a plurality of aggregators communicatively connected to the collectors to form a consistent hash ring, the received time series metrics data for the plurality of performance metrics, wherein each aggregator is assigned to aggregate all received time series metrics data for one or more of the plurality of performance metrics;
• determining, at a coordinator communicatively connected to the plurality of collectors and the plurality of aggregators, whether the hash ring has changed;
• and
• communicating, at the coordinator, information on the determined change to the plurality of collectors.

A non-transitory computer readable medium embodying instructions when executed by a processor to cause operations to be performed including:

• receiving, at a plurality of collectors, time series metrics data for a plurality of performance metrics from one or more agents instrumented into monitored applications;
• aggregating, at a plurality of aggregators communicatively connected to the collectors to form a hash ring, the received time series metrics data for the plurality of performance metrics, wherein each aggregator is assigned to aggregate all received time series metrics data for one or more of the plurality of performance metrics;
• determining, at a coordinator communicatively connected to the plurality of collectors and the plurality of aggregators, whether one of the plurality of the aggregators in the hash ring has crashed;
• and
• performing a repair job to fix data corruption caused by the crashed aggregator.
