Abstract: Embodiments are directed to capturing packets on a network. A snapshot value may be provided for a network monitoring computer (NMC). If the NMC may be provided packets of a network flow, characteristics of the network flow may be monitored. If the characteristics of the network flow indicate that a flow turn may be occurring on the network flow, the snapshot value may be modified by increasing it to a provided value. If conditions indicate that the flow turn may be complete, the snapshot value maybe reset by decreasing it to another provided value. A portion of each of the packets may be captured by the NMC, such that the size of the portion may be equivalent to the snapshot value. The captured portion of each of the packets may be stored in a memory of the NMC.

Abstract: Embodiments are directed to monitoring flows of packets over a network. If a network monitoring computer (NMC) in a cluster of NMCs observes a new network flow, the NMC may perform a variety of actions to determine the NMC that is responsible for monitoring the new network flow. Network traffic associated with the new network flow may be buffered in a non-transitory processor readable media. The new network flow may be registered with the plurality of NMCs, providing an identifier that corresponds to one NMC. Registering may include, assigning the NMC a responsibility to monitor the new network flow. If the identifier corresponds to the NMC that observed the new network flow, the network traffic associated with the new network flow is processed using that NMC. If the identifier corresponds to another NMC, the buffered network traffic is forwarded to the other NMC.
