Abstract

Gathering tenant usage data of server resources. A method includes a server in a cluster providing server resources for one or more tenants of the server. Data is stored in a local usage cache at the server. The data characterizes the resources provided to the one or more tenants of the server. At the server, data stored in the local usage cache is aggregated on a tenant basis, such that data is aggregated for given tenants. The aggregated data is sent to a distributed cache. At the server, aggregated data from other servers in the cluster is received from the distributed cache. The aggregated data from other servers in the cluster is globally aggregated and stored at an aggregated usage cache at the server in the globally aggregated form.

Claims

1. In a computing environment, a method of gathering tenant usage data of server resources, the method comprising:

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.

2. The method of claim 1, wherein the distributed cache automatically sends the aggregated data from other servers in the cluster to the server.

3. The method of claim 1, further comprising the server pulling the aggregated data, from other servers in the cluster, from distributed cache for a particular set of tenants.

4. The method of claim 3, wherein the server pulls the aggregated data, from other servers in the cluster, for tenants using the server.

7. The method of claim 1, wherein receiving from the distributed cache the aggregated data from other servers in the cluster is performed according to a user configurable schedule.

5. The method of 1 further comprising throttling using the aggregated data from other servers in the cluster.

6. The method of 1 further comprising using the aggregated data from other servers in the cluster to generate analysis statistics.

8. One or more computer readable 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.

9. The one or more computer readable media of claim 8, wherein the distributed cache automatically sends the aggregated data from other servers in the cluster to the server.

10. The one or more computer readable media of claim 8, further comprising the server pulling the aggregated data, from other servers in the cluster, from distributed cache for a particular set of tenants.

11. The one or more computer readable media of claim 10, wherein the server pulls the aggregated data, from other servers in the cluster, for tenants using the server.

12. The one or more computer readable media of claim 8 further comprising throttling using the aggregated data from other servers in the cluster.

13. The one or more computer readable media of claim 8 further comprising using the aggregated data from other servers in the cluster to generate analysis statistics.

14. The one or more computer readable media of claim 8, wherein receiving from the distributed cache the aggregated data from other servers in the cluster is performed according to a user configurable schedule.

15. 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.

16. The cluster system of claim 15, further comprising an offline store configured to persist usage data separate from the servers and the distributed cache.

17. The cluster system of claim 15, further comprising a user interface configured to receive user input for defining a schedule of when data is sent from the distributed cache to the servers.

18. The cluster system of claim 15, further comprising one or more throttling modules at the servers configured to throttle cluster services for tenants based on the globally aggregated data.

19. The cluster system of claim 15, further comprising one or more analysis modules at the servers configured to generate analysis statistics for tenant usage of cluster resources.

20. The cluster system of claim 15, wherein the distributed cache is configured to globally aggregate usage information and send the globally aggregated usage information to the aggregated caches in the plurality of aggregated caches.
