Abstract: An approach is provided for implementing memory profiling aggregation. A hardware aggregator provides memory profiling aggregation by controlling the execution of a plurality of hardware profilers that monitor memory performance in a system. For each hardware profiler of the plurality of hardware profilers, a hardware counter value is compared to a threshold value. When a threshold value is satisfied, execution of a respective hardware profiler of the plurality of hardware profilers is initiated to monitor memory performance. Multiple hardware profilers of the plurality of hardware profilers may execute concurrently and each generate a result counter value. The result counter values generated by each hardware profiler of the plurality of hardware profilers are aggregated to generate an aggregate result counter value. The aggregate result counter value is stored in memory that is accessible by a software processes for use in optimizing memory-management policy decisions.
