Abstract
Values of a metric are provided at irregular intervals. A forgetting factor is calculated based on a difference between the intervals, and a statistical parameter is computed using the forgetting factor that causes different weights to be placed on the corresponding values of the metric, where the statistical parameter is part of an adaptive baseline.
Claims20
A method comprising:
- determining, by a system having a processor, an adaptive baseline that includes at least one statistical parameter based on values of a metric that are provided at irregular intervals;
- wherein the determining includes:
- computing the statistical parameter using a forgetting factor that causes different weights to be placed on the corresponding values of the metric;
- and
- calculating the forgetting factor based on a difference between the intervals.
2 more elements
An article comprising at least one machine-readable storage medium storing instructions that upon execution cause a system to:
- receive sample values of a metric at irregular intervals;
- computing a forgetting factor that varies in value according to a difference between the intervals;
- and
- computing a statistical parameter based on the forgetting factor, the forgetting factor causing different weights to be placed on corresponding sample values of the metric, and the statistical parameter being part of an adaptive baseline for use in detecting abnormal behavior of a monitored environment based on values of the metric.

A computer system comprising:
- at least one processor to:
- receive values of a metric that are provided at irregular intervals;
- calculate a forgetting factor based on a difference between the intervals;
