Abstract
A method for generating alerts from a periodically sampled system is disclosed. The method includes maintaining a sampling window having a predefined number of most-recently collected samples. The method further includes calculating an alert value, the alert value representing a ratio of a first value to a total number of samples in the sampling window, the first value representing a total number of samples in the sampling window having parameters exceeding a predefined sample alert threshold. The method additionally includes generating a first alert if the alert value exceeds a predefined alert threshold.
Claims19
A method for generating alerts from a periodically sampled system, comprising:
- maintaining a sampling window having a predefined number of most-recently collected samples;
- calculating an alert value, said alert value representing a ratio of a first value to a total number of samples in said sampling window, said first value representing a total number of samples in said sampling window having parameters exceeding a predefined sample alert threshold;
- and
- generating a first alert if said alert value exceeds a predefined alert threshold, wherein said first alert is generated for a sampling period that results in said alert value exceeding said predefined alert threshold only if an alert is not generated in an immediately preceding sampling period.
An article of manufacture comprising a program storage medium having computer readable code embodied therein, said computer readable code being configured to generate alerts from a periodically sampled system, comprising:
- computer readable code for maintaining a sampling window having a predefined number of most-recently collected samples;
- computer readable code for calculating an alert value, said alert value representing a ratio of a first value to a total number of samples in said sampling window, said first value representing a total number of samples in said sampling window having parameters exceeding a predefined sample alert threshold;
- and
- computer readable code for generating a first alert if said alert value exceeds a predefined alert threshold, wherein said first alert is generated for a sampling period that results in said alert value exceeding said predefined alert threshold only if an alert is not generated in an immediately preceding sampling period.
A method for fine-tuning an alert signal obtained from a periodically sampled system, comprising:
- providing an alert signal generator, said alert signal generator having
- first logic for maintaining a sampling window at a constant window size, said sampling window containing most-recently collected samples,
- second logic for calculating an alert value, said alert value representing a ratio of a first value to a total number of samples in said sampling window, said first value representing a total number of samples in said sampling window having parameters exceeding a sample alert threshold, and
- third logic for generating a first alert if said alert value exceeds an alert threshold, wherein said first alert is generated for a sampling period that results in said alert value exceeding said alert threshold only if an alert is not generated in an immediately preceding sampling period;
- and
- providing a control panel having a plurality of user-manipulable controls, said plurality of user-manipulable controls including at least one of a first control for varying said window size, a second control for varying said sample alert threshold, and a third control for varying said alert threshold.
