Scalable real time metrics management

A method of analyzing metric data sets associated with a set of elements in a network, the method comprising:

• aggregating, at a first rate, a plurality of metric data sets associated with the set of network elements to generate a plurality of first aggregated results;
• aggregating, at a second rate, the plurality of first aggregated results to generate a plurality of second aggregated results, the second rate being a lower rate than the first rate;
• and
• analyzing the plurality of second aggregated results in order to monitor the set of network elements,
• said first and second aggregation operations performed to reduce amount of memory used to store metric data sets by producing aggregated results for said analyzing operation.

A non-transitory computer readable medium storing a program for analyzing metric data sets associated with a set of elements in a network, the program executable by a processing unit, the program comprising sets of instructions for:

• aggregating, at a first rate, a plurality of metric data sets associated with the set of network elements to generate a plurality of first aggregated results;
• aggregating, at a second rate, the plurality of first aggregated results to generate a plurality of second aggregated results, the second rate being a lower rate than the first rate;
• and
• analyzing the plurality of second aggregated results in order to monitor the set of network elements,
• said first and second aggregation operations performed to reduce amount of memory used to store metric data sets by producing aggregated results for said analyzing operation.
