20110161048 | Method to Optimize Prediction of Threshold Violations Using Baselines - A baseline technique allows reducing the number of threshold violation predictions that need to be generated in a performance monitoring system. One or more baselines may be calculated based on long-term trends in a monitored metric. If the metric is within the baseline, then predictions regarding short-term trends in the metric may be omitted. If the metric is outside the baseline, then short-term trends may be analyzed to predict possible threshold violations. | 06-30-2011 |
20110238376 | Automatic Determination of Dynamic Threshold for Accurate Detection of Abnormalities - An improved performance management technique allows automatic determination dynamic thresholds of a metric based on a baseline of the matching pattern. A pattern matching process is conducted against a set of baseline patterns to find the matching pattern. If a matching pattern is found, the baseline of the matching pattern is used as the dynamic threshold. A series of sanity checks are performed to reduce any false alarms. If the metric does not follow any pattern, a composite of baselines is selected as the dynamic threshold. | 09-29-2011 |

20100050023 | SYSTEM, METHOD AND COMPUTER PROGRAM PRODUCT FOR OPTIMIZED ROOT CAUSE ANALYSIS - Embodiments disclosed herein can significantly optimize a root cause analysis and substantially reduce the overall time needed to isolate the root cause or causes of service degradation in an IT environment. By building on the ability of an abnormality detection algorithm to correlate an alarm with one or more events, embodiments disclosed herein can apply data correlation to data points collected within a specified time window by data metrics involved in the generation of the alarm and the event(s). The level of correlation between the primary metric and the probable cause metrics may be adjusted using the ratio between theoretical data points and actual points. The final Root Cause Analysis score may be modified depending upon the adjusted correlation value and presented for user review through a user interface. | 02-25-2010 |

20110238377 | Auto Adjustment of Baseline on Configuration Change - A baseline adjusting technique allows automatically adjust the baselines of metrics affected by a configuration change a monitored system. If a configuration change is detected, a performance management system retrieves linkages between the changed configuration parameter and one or more metrics. The performance management system then adjusts the baselines of the metric using the baseline adjusting algorithm retrieved from the linkage. | 09-29-2011 |
