A networking system may include one or more nodes communicating with each other. The nodes may communicate via one or more links, which a switch or other structure may provide. The networking system may include one or more pools of at least one network diagnostic module. A network diagnostic module may test one or more links and may be configured to rove among a plurality of links. The networking system may include an alarm module.

Pool-based network diagnostic systems and methods

A networking system may include one or more nodes communicating with each other. The nodes may communicate via one or more links, which a switch or other structure may provide. The networking system may include one or more pools of at least one network diagnostic module. A network diagnostic module may test one or more links and may be configured to rove among a plurality of links. The networking system may include an alarm module. The alarm module may configure one or more network diagnostic modules to test a link. Preferably, the alarm module may, at least partially in response to a first network diagnostic module detecting particular conditions on a link, configure one or more other network diagnostic modules to test a link. The alarm module may configure the one or more other network diagnostic modules according to priority.

Network monitoring is performed using a three-tiered distributed computing system architecture, including a data source tier, a portal tier and a client tier. The data source tier monitors the physical data on the network medium using multiple data collection sources connected to the network. The probes analyze network data and generate fundamental metrics that describe attributes of the network data. The portal tier encapsulates the fundamental metrics along with executable processor objects into data containers having a predefined format. The processor objects contain logic that operates on fundamental metrics contained in the data containers in a manner so as to generate new derived metrics or aggregates of metric data. The data containers may be requested by the client tier, which executes the processor objects and provides a user interface for displaying various types of network information derived from the contents of data containers.

Deferred processing of continuous metrics

A network monitoring architecture and methodology enabling performance detection and diagnostics in storage area networks or other networks. The network monitoring is performed using a three-tiered distributed computing system architecture, including a data source tier, a portal tier and a client tier. The data source tier monitors the physical data on the network medium using multiple data collection sources, or data probes, connected to the network. The probes analyze network data and generate metrics that describe attributes of the network data. The metrics are used by the data portal tier, which is the second tier of the system. The portal tier encapsulates the metrics into data containers. The data containers may be requested by the client tier, which is the third tier in the network monitoring system. The client tier provides a user interface for displaying various types of network information derived from the contents of data containers.
