Abstract

It is detected when an administrator begins or finishes performing remote administrative activity. In response, the polling interval is modified. When the level of remote administrative activity increases, the polling interval is decreased, thereby directing the managed clients to poll the server more frequently. When the level of remote administrative activity decreases, the polling interval is increased, thereby directing the managed clients to poll the server less frequently. By dynamically adjusting the polling interval based on remote administrative activity, a balance is struck between scalability and usability.

Claims

transmitting successive ones of the intermediate polling intervals to the at least one of the plurality of managed client computers, by a server computer; and

subsequently transmitting the second polling interval to the at least one of the plurality of managed client computers, by a server computer.

7. The method of claim 1 wherein detecting an indication of a change in a level of remote administrative activity further comprises:

detecting data that indicates a likelihood of an upcoming change in the level of remote administrative activity, by a server computer.

8. The method of claim 7 wherein detecting data that indicates a likelihood of an upcoming change in the level of remote administrative activity further comprises detecting, by a server computer, performance of at least one step from a group of steps consisting of:

at least one managed client computer entering an alert state;

at least one managed client computer entering an emergency state;

at least one managed client computer being in an alert state;

at least one managed client computer being in an emergency state;

a pattern in past remote administrative activity.

9. At least one non-transitory computer readable storage medium storing a computer program product for, when executed by a processor, automatically adjusting polling intervals by a server computer performing remote administrative activity on a managed client computer, the computer program product comprising:

program code for receiving polling inquiries at a server computer from managed client computers according to a first polling interval, a polling inquiry allowing remote administrative activity to be executed by the server computer on a managed client computer;

program code for detecting an indication of a change in status on the managed client computer from the server computer, wherein the change in status will cause a change in a level of actual remote administrative activity performed by the server computer on at least one of a plurality of managed client computers;

program code for, in response to detecting the indication of a change in the level of actual remote administrative activity, automatically calculating a second polling interval for polling inquiries correlating to the level of actual remote administrative activity, by the server computer, the second polling interval to be used by the at least one of the plurality of managed client computers, comprising;

in response to detecting an increase in the level of actual remote administrative activity, automatically calculating a decreased polling interval, and

in response to detecting a decrease in the level of actual remote administrative activity, automatically calculating an increased polling interval;
