Abstract: Systems, methods, and computer-readable media for identifying a spanning tree loop in a network environment. Spanning tree loop indicators occurring in a network environment that utilizes a spanning tree protocol are identified. The spanning tree loop indicators are correlated to identify correlated spanning tree loop indicators within the network environment. A potential spanning tree loop is recognized from a plurality of the correlated spanning tree loop indicators based on indicator types of the correlated spanning tree loop indicators. The potential spanning tree loop is remedied in the network environment in response to recognizing the potential spanning tree loop in the network environment.

Abstract: Determining the importance of network devices based on a discovered topology, managed endpoints, and activity may be provided. First, topology data may be received corresponding to a network comprising a plurality of devices. Then, a topology matrix may be created representing the topology data. Next, a stationary matrix may be determined from the topology matrix. The stationary matrix may indicate a relative importance of each of the plurality of devices within the network. A health score may then be determined for at least one of the plurality of devices based on the relative importance of the at least one of the plurality of devices. The health score may be determined using the stationary matrix.

Abstract: In one embodiment, a logging process initiates a trace of an execution flow across a plurality of processes, and creates a log context for the trace, the log context having a universally unique identifier (UUID) and an indication that the trace is to be performed as the plurality of processes are executed during the execution flow. The logging process manages passage of the log context across the plurality of processes during the execution flow, and gathers log entries from the plurality of processes based on the UUID for the trace, where the log entries were created based on the indication being within the log context. As such, the logging process may stitch the log entries into a flow execution log for the trace of the execution flow.

Abstract: Methods and apparatus for compensating for time-based sampling using packet elimination are disclosed herein. An example method may be implemented in a network device communicatively connected to a network. The method may include: receiving a packet over the network at a monitoring point; replicating the received packet; determining whether to sample the replicated packet using a time-based sampling scheme; upon determining that the replicated packet should be sampled, queuing the replicated packet to a port of the network device; determining whether to eliminate the queued packet by comparing a configured sample rate with a current sample rate; upon determining that the current sample rate is less than the configured sample rate, exporting the queued packet from the network device; and upon determining that the current sample rate is greater than or equal to the configured sample rate, dropping the queued packet.

Abstract: A method is provided in one example embodiment and includes receiving a packet flow from a data source at a network element; determining a control value for controlling a sample rate for the packet flow; and recalculating the control value based on a number of packets received and a number of sampled packets. In more particular embodiments, the method can include assigning a particular identifier to a particular packet of the packet flow; generating an input access control list for the data source; and matching the particular identifier to an output port of the network element. In yet other embodiments, the method can include generating a copy of a particular packet of the packet flow; and forwarding the copy of the particular packet to an output access control list based on an assigned quality of service (QoS) group.
