摘要： A system and method for automatically constructing a baseline for an attribute of a monitored system, calculating a threshold based on the constructed baseline, and feeding the threshold back into the monitored system is presented. In accordance with the invention, a metric corresponding to an attribute of interest of a monitored system is extracted and compared with a current normal threshold associated with the attribute. An event notification is generated if the extracted metric is not within a limit defined by the current normal threshold. A baseline is calculated based on a relevant subset of extracted metrics, from which a new current normal threshold is calculated. The current normal threshold is reconfigured with the new current normal threshold. In preferred embodiments, an alarm is generated if one or more event notifications meet the conditions of pre-specified rules. Newly calculated current normal thresholds are limited to a service level limit which defines a boundary of the acceptable level of operation the attribute, and a service level exception is generated, if the newly calculated current normal threshold is not within that limit. Reports are generated which summarize the performance of the monitored attributes, indicate which monitored attributes are out-of-control, and prioritize the order in which out-of-control attributes receive available engineering resources.

摘要翻译： 提出了一种用于自动构建被监视系统的属性的基线的系统和方法，基于构建的基线计算阈值，并将该阈值馈送回所监视的系统。 根据本发明，提取与被监视系统的感兴趣属性对应的度量，并将其与与该属性相关联的当前正常阈值进行比较。 如果所提取的度量不在当前正常阈值所限定的限制内，则生成事件通知。 基于提取的度量的相关子集计算基线，计算新的当前正常阈值。 当前正常阈值用新的当前正常阈值重新配置。 在优选实施例中，如果一个或多个事件通知符合预定规则的条件，则产生报警。 如果新计算的当前正常阈值不在该限度内，则新计算的当前正常阈值被限制为定义属性的可接受操作等级的边界并且生成服务级别异常的服务级别限制。 生成的报告总结了受监视属性的性能，指出哪些监视属性失控，并且优先处理失控属性接收可用工程资源的顺序。

摘要： A network management node monitors network attributes of a network. The network management node is connected to network devices through the network and receives data values associated with measured network attributes from said network devices. The data values are stored in the network management node and a baseline value and rearm baseline value for a network attribute are calculated from a plurality of the received data values measured during a first period of time (e.g., a first time bucket). These data values are compared to the baseline value, and an alarm is generated in response to at least one of these data values exceeding the baseline value. The alarm is reset if at least one subsequently measured data value is below the rearm baseline value. The baseline value and rearm baseline value are recalculated from received data values measured during subsequent time buckets. Data values measured during the subsequent time buckets are compared to corresponding baseline and rearm baseline values.

摘要翻译： 网络管理节点监视网络的网络属性。 网络管理节点通过网络连接到网络设备，并从所述网络设备接收与测量的网络属性相关联的数据值。 数据值存储在网络管理节点中，并且根据在第一时间段（例如，第一时间段）期间测量的多个接收到的数据值来计算网络属性的基准值和重新设定的基准值。 将这些数据值与基准值进行比较，并响应于这些数据值中的至少一个超过基准值而产生报警。 如果至少一个随后测量的数据值低于重新设定的基准值，则报警将复位。 从后续时间段中测量的接收数据值重新计算基准值和重新计算基线值。 在后续时间段中测量的数据值与相应的基线和重新设定的基准值进行比较
