    摘要： Network traffic information for nodes of a first logical hierarchy is stored at a monitoring device according to ranks of the nodes within the logical hierarchy as determined by each node's position therein and user preferences. At least some of the network traffic information stored at the network monitoring device may then be reported to another network monitoring device, where it can be aggregated with similar information from other network monitoring devices. Such reporting may occur according to rankings of inter-node communication links between nodes of different logical hierarchies of monitored nodes.

    摘要： During monitoring of IP network traffic, network application monitoring metrics are extracted, aggregated into logical group types and subsequently analyzed by identifying group sets of the logical group types, correlating anomalous conditions across the logically grouped and aggregated metrics, and isolating the anomalous conditions to one or more related members of the logical group types. The metrics may include usage metrics, network performance metrics and application performance metrics.

    摘要： A distributed network monitoring system includes a central monitoring device configured to fetch network traffic information from one or more remote monitoring devices in response to receiving a notification from the remote monitoring devices that the network traffic information is available, the remote monitoring devices being communicatively coupled to the central monitoring device. The network traffic information is associated with a timestamp which indicates a time period at which the network traffic information was collected by the remote monitoring devices. The central monitoring device further synchronizes the network traffic information from the remote monitoring devices by comparing the timestamp of the network traffic information with a system timestamp provided by a system clock or network time protocol (NTP) server. The network traffic information is identified as unavailable if the timestamp cannot be located when compared to the system timestamp. In addition, the central monitoring device starts a timeout wait period for the remote monitoring device with the unavailable network traffic information and further ceases collecting the network traffic information if the timeout wait period expires. The synchronized network traffic information is further consolidated to provide information regarding the overall performance of a network system.
