What is Network Metadata?
The human view in Network Visualization!
Network Metadata is human readable data that describes your network traffic. It is generated and consumed by network traffic monitoring systems to analyse and report on network and user activity. This type of continuous monitoring is concerned with users, the apps they use and the data they access. It is generally not used for monitoring the health of the network fabric and attached devices.
The graphic below depicts some of the available technologies for continuous network traffic monitoring and how they relate to each other in terms of the information provided and the cost and complexity of implementation.
Network Metadata is used to fill the gap between the “not-enough-detail” SNMP switch port counters and “too-much-complexity, too expensive” full packet capture systems.
