Abstract
A specification unit (15b) specifies a path of traffic on the basis of past flow information. A determination unit (15c) determines a network device on the specified path for traffic related to a designated event.
Claims20
A collection device comprising a processor configured to execute operations comprising:
- receiving a designated event that has occurred in a first network device;
- identifying a path of traffic on the basis of past flow information of a normal data traffic, and the normal data traffic describes data at least in the first network device;
- determining a second network device on the specified path for traffic related to the designated event, wherein the second network device collects flow statistical information of the normal data traffic according a first collection granularity and transmits the flow statistical information over a network for storing in a memory device;
- and
- causing the second network device to collect, future flow statistical information of a future data traffic according a second collection granularity and transmit the future flow statistical information over the network for storing in the memory device, wherein the second collection granularity is distinct from the first collection granularity.

A computer-executable method, comprising:
- a receiving step of receiving a designated event that has occurred in a first network device;
- a specification step of specifying a path of traffic on the basis of past flow information of a normal data traffic, and the normal data traffic describes data at least in the first network device;
- a determination step of determining a second network device on the specified path for traffic related to the designated event, wherein the second network device collects flow statistical information of the normal data traffic according a first collection granularity and transmits the flow statistical information over a network for storing in a memory device;
- and
- causing the second network device to collect, future flow statistical information of a future data traffic according a second collection granularity and transmit the future flow statistical information over the network for storing in the memory device, wherein the second collection granularity is distinct from the first collection granularity.

A computer-readable non-transitory recording medium storing a computer-executable program instructions that when executed by a processor cause a computer to execute operations comprising:
- a receiving step of receiving a designated event that has occurred in a first network device;
- a specification step of specifying a path of traffic on the basis of past flow information of a normal data traffic, and the normal data traffic describes data at least in the first network device;
- a determination step of determining a second network device on the specified path for traffic related to the designated event, wherein the second network device collects flow statistical information of the normal data traffic according a first collection granularity and transmits the flow statistical information over a network for storing in a memory device;
- and
- causing the second network device to collect, future flow statistical information of a future data traffic according a second collection granularity and transmit the future flow statistical information over the network for storing in the memory device, wherein the second collection granularity is distinct from the first collection granularity.
