Metrics aggregation

A storage system that comprises a group of compute entities, wherein each compute entity (CE) of the group of compute entities, is configured to generate a compute entity (CE) storage metric by each CE of a group of CEs to provide multiple CE storage metrics, wherein the multiple CE storage metrics are related to a monitoring period;

• and
• wherein the group of CEs are configured to calculate, during a calculation period, a group storage metric based on the multiple CE storage metrices;
• wherein the calculating comprises performing multiple calculations iterations, wherein each calculation iteration comprises (a) selecting an updating CE that belongs to the group of CEs and was not previously selected during the calculation period, (b) accessing, by the updating CE, a shared data structure that stores the group storage metric, and (c) updating the group storage metric using the CE storage metric of the updating CE.
