What does traffic-based discovery utilize in base systems?

Traffic-based discovery in base systems leverages TCP connection data, along with the netstat and lsof commands, to identify and map dependencies and interactions among various services and applications.

By utilizing the TCP connection data, the discovery process can monitor active network connections to determine which services are communicating with each other. The netstat command provides a snapshot of the network connections that a system has at a given moment, revealing what ports are in use and which services are linked over those connections. Similarly, the lsof command lists open files and the processes that opened them, which includes network sockets, thus providing insights into which applications are actively communicating.

Through this method, a more comprehensive understanding of the system's landscape can be formed, supporting effective service mapping and dependency relationships. This is critical for IT operations where maintaining an accurate picture of network interactions is necessary for troubleshooting, performance monitoring, and service continuity.
