Near-real time distributed usage aggregation system

One or more physical computer readable storage media comprising computer executable instructions that when executed by one or more processors cause one or more processors to perform the following:

• a server in a cluster providing server resources for one or more tenants of the server;
• storing data in a local usage cache at the server, the data characterizing the resources provided to the one or more tenants of the server;
• at the server, aggregating data stored in the local usage cache on a tenant basis, such that data is aggregated for given tenants;
• sending the aggregated data to a distributed cache;
• receiving from the distributed cache aggregated data from other servers in the cluster;
• and
• storing at a local aggregated usage cache, the aggregated data from other servers in the cluster as globally aggregated data.

A cluster system including functionality for gathering tenant usage data of server resources in the cluster system, the cluster system comprising:

• a plurality of servers, the plurality of servers being configured to provide resources to tenants of the cluster system;
• a plurality of local caches, with a local cache on each of the servers in the plurality of servers, each local cache storing usage information characterizing usage of resources on the server on which it is located for tenants using that server;
• a distributed cache, the distributed cache storing usage information from all of the servers in the plurality of servers;
• and
• a plurality of aggregated caches, with an aggregated cache on each of the servers in the plurality of servers, each aggregated cache storing globally aggregated usage information for all servers and tenants of the cluster based on aggregated usage information for each of the servers in the plurality of servers sent from the distributed cache.
