Abstract
Techniques are described for monitoring a performance metric. A multiple modeling approach is used to improve predictive analysis by avoiding the issuance of warnings during spikes which occur as a part of normal system processing. This approach increases the accuracy of predictive analytics on a monitored computing system, does not require creating rules defining periodic processing cycles, reduces the amount of data required to perform predictive modeling, and reduces the amount of CPU required to perform predictive modeling.
Claims7
A computer-implemented method for monitoring a performance metric, the method comprising:
- determining a value of a performance metric for a current sampling period;
- upon determining the value of the performance metric passes a threshold derived from a first model of expected behavior of the performance metric, evaluating the value of performance metric according to a second model of expected behavior of the performance metric;
- and
- upon determining the value of the performance metric passes a threshold derived from the second model, generating an alert message.
