A service level agreement between a network service provider and a network user may require that specified service metrics or parameters be maintained within predetermined limits. To reduce the chance those limits (and the service level agreement) will be violated, the service metric is sampled periodically over successive sampling intervals. The mean value and the standard deviation of the set of samples obtained during the most recent sampling interval are used to screen out unreliable data. If the set of samples satisfies the reliability screening, the set is used in combination with past acceptable sets to determine the trend in the sampled service metric. If the trend is toward a violation, the time of the violation is predicted based on the assumption the current trend will continue. If the predicted time of violation is sufficiently near the current time, an alert is sent to the service provider to permit the service provider to initiate anticipatory corrective action.

Method, system and program product for managing network performance

Monitoring compliance with a service level agreement is provided by generating an early warning notification indicating that failure to meet a service level objective of the service level agreement by a resource is about to occur. The early warning notification may include an indication of how close the resource is to failing to meet the service level objective.

Early warning of potential service level agreement violations

The present invention provides a method, system, and computer program product for displaying calendar-based service level objective (SLO) results and breach values. The method comprises: generating a plurality of area charts, wherein each area chart displays SLO result data for a different calendar period and for a different state of the service, and wherein each area chart displays a start and end of a respective calendar period; generating a first line chart displaying calendar periods corresponding to a predetermined state of the service, wherein the first line chart displays a start and end of each calendar period corresponding to the predetermined state; and overlaying and displaying the plurality of area charts and the first line chart to provide a first composite view of SLO information for the service, wherein the calendar periods in the plurality of area charts and the first line chart do not overlap.
