PROBLEM TO BE SOLVED: To provide a method that can capture a packet on a network at a high transmission rate and, at the same time, can acquire related information of the packet.SOLUTION: The present invention discloses a network monitoring method and apparatus. The network monitoring method includes: receiving a packet transmitted on a network, where the packet has flow information that indicates a network flow for transmission of the packet; acquiring the flow information of the packet; detecting whether a metadatabase includes the flow information corresponding the packet, where the metadatabase is used to store metadata and flow information associated with the metadata; generating, according to a detection result about the flow information, metadata related to the transmission of the packet, and associating the metadata with the corresponding flow information; and storing in the metadatabase the generated metadata and the flow information associated with the generated metadata.SELECTED DRAWING: Figure 3 |
