A computer system to execute a method of data aggregation in a multi-tenant system, the computer system comprising:

• a non-transitory machine-readable storage medium having stored therein a data aggregation manager;
• and
• a processor coupled to the non-transitory machine-readable storage medium, the processor to execute the data aggregation manager, the data aggregation manager to receive an event from an activity tracking component, to generate a first hash value based on a first identifier in the event, to generate a second hash value based on a second identifier in the event, and to store event message information to an entry of a metric storage database in a partition according the first hash value and the second hash value.
