Abstract

Server resource-aware discovery of client application resources is described. A server requests for clients to discover their application resources. If a utilization of a server resource does not exceed a server resource utilization threshold, the server fetches a copy of a client application resource from a client at a fetch rate. If the utilization of the server resource exceeds the server resource utilization threshold, the server fetches the copy of the client application resource from the client at a lesser fetch rate.

First claim

What is claimed is:

1. A system for server resource-aware discovery of client application resources, comprising:
one or more processors; and
a non-transitory computer readable medium storing a plurality of instructions, which

when executed, cause the one or more processors to:
request, by a server, a plurality of clients, comprising a client, to discover a plurality of client application resources, comprising a client application resource;
identify a utilization of a server resource by the server;
determine whether the utilization of the server resource exceeds a server resource utilization threshold;
fetch, by the server, a copy of the client application resource from the client at a first fetch rate, in response to a determination that the utilization of the server resource does not exceed the server resource utilization threshold; and
fetch, by the server, the copy of the client application resource from the client at a second fetch rate, which is less than the first fetch rate, in response to a determination that the utilization of the server resource exceeds the server resource utilization threshold, wherein fetching at the second fetch rate comprises one of fetching a subset of the copy of the client application resources during each fetch or pausing the fetching of the copy of the client application resource, until a subsequent determination that the utilization of the server resource does not exceed the server resource utilization threshold.

2. The system of claim 1 , wherein requesting the plurality of clients to discover the plurality of client application resources comprises making a plurality of application programming interface calls that request a plurality of agents corresponding to the plurality of clients to discover the plurality of client application resources, and providing a time stamp corresponding to a fetched copy of a client application resource.

3. The system of claim 1 , wherein the plurality of instructions further causes the processor to receive a change notification for the client application resource from the client, wherein fetching the copy of the client application resource from the client is in response to receiving the change notification for the client application resource from the client.

4. The system of claim 1 , wherein the utilization of the server resource comprises a use of at least one of a central processing unit and a memory associated with the server.

5. The system of claim 1 , wherein determining whether the utilization of the server resource exceeds the server resource utilization threshold is based on at least one of a job that is executing on the server and a job that is pending execution on the server.

6. A computer-implemented method for server resource-aware discovery of client application resources, the computer-implemented method comprising:
requesting, by a server, a plurality of clients, comprising a client, to discover a plurality of client application resources, comprising a client application resource;
receiving a change notification for a client application resource of the plurality of client resources from a client of the plurality of clients;
identifying a utilization of a server resource by the server;
determining whether the utilization of the server resource exceeds a server resource utilization threshold;
fetching, by the server, a copy of the client application resource from the client at a first fetch rate, in response to a determination that the utilization of the server resource does not exceed the server resource utilization threshold; and
fetching, by the server, the copy of the client application resource from the client at a second fetch rate, which is less than the first fetch rate, in response to a determination that the utilization of the server resource exceeds the server resource utilization threshold, wherein fetching at the second fetch rate comprises one of fetching a subset of the copy of the client application resources during each fetch or pausing the fetching of the copy of the client application resource, until a subsequent determination that the utilization of the server resource does not exceed the server resource utilization threshold.

7. The computer-implemented method of claim 6 , wherein requesting the plurality of clients to discover the plurality of client application resources comprises making a plurality of application programming interface calls that request a plurality of agents corresponding to the plurality of clients to discover the plurality of client application resources, and providing a time stamp corresponding to a fetched copy of a client application resource.

8. The computer-implemented method of claim 6 , wherein the computer-implemented method further comprises receiving a change notification for the client application resource from the client, wherein fetching the copy of the client application resource from the client is in response to receiving the change notification for the client application resource from the client.

9. The computer-implemented method of claim 6 , wherein the utilization of the server resource comprises a use of at least one of a central processing unit and a memory associated with the server.

10. The computer-implemented method of claim 6 , wherein determining whether the utilization of the server resource exceeds the server resource utilization threshold is based on at least one of a job that is executing on the server and a job that is pending execution on the server.

11. A computer program product, comprising a non-transitory computer-readable medium having a computer-readable program code embodied therein to be executed by one or more processors, the program code including instructions to:
request, by a server, a plurality of clients, comprising a client, to discover a plurality of client application resources, comprising a client application resource;
receive a change notification for a client application resource of the plurality of client resources from a client of the plurality of clients;
identify a utilization of a server resource by the server;
determine whether the utilization of the server resource exceeds a server resource utilization threshold;
fetch, by the server, a copy of the client application resource from the client at a first fetch rate, in response to a determination that the utilization of the server resource does not exceed the server resource utilization threshold; and
fetch, by the server, the copy of the client application resource from the client at a second fetch rate, which is less than the first fetch rate, in response to a determination that the utilization of the server resource exceeds the server resource utilization threshold, wherein fetching at the second fetch rate comprises one of fetching a subset of the copy of the client application resources during each fetch or pausing the fetching of the copy of the client application resource, until a subsequent determination that the utilization of the server resource does not exceed the server resource utilization threshold.

12. The computer program product of claim 11 , wherein requesting the plurality of clients to discover the plurality of client application resources comprises making a plurality of application programming interface calls that request a plurality of agents corresponding to the plurality of clients to discover the plurality of client application resources, and providing a time stamp corresponding to a fetched copy of a client application resource.

13. The computer program product of claim 11 , wherein the program code includes further instructions to receive a change notification for the client applicati
