Apparatus, system, and method for self-regulating sampling domains within network devices

Abstract:

A disclosed method may include (1) sampling, by way of at least one CPU on a network device, packets traversing a network in connection with at least one communication session that involves computing devices, (2) calculating a total number of packets sampled by way of the CPU over a certain period of time, (3) identifying a sampling threshold that represents a target number of packets to be sampled by way of the CPU over the certain period of time, (4) determining that the total number of packets sampled over the certain period of time exceeds the sampling threshold, and in response to determining that the total number of packets sampled exceeds the sampling threshold, (5) decreasing a sampling rate at which the CPU is to sample subsequent packets traversing the network in connection with the communication session. Various other systems and methods are also disclosed.
