74:, which is system self-reported information typically in the form of logs sourced from elements like network routers, servers, and other equipment. Unlike those forms of machine-generated data, which are dependent on the logging configurations of those devices, wire data is defined by wire and transport protocols. There is a small amount of overlap between wire data and machine-generated data but also significant differences. For example, web server logs typically record 54:, wire data will play a more important role than machine data for analytics in the future: "While log data will certainly have a role in future monitoring and analytics, it is wire data—radically rethought and used in new ways—that will prove to be the most critical source of data for availability and performance management over the next five years." 46:
Wire data is the observed behavior and communication between networked elements which is an important source of information used by IT operations staff to troubleshoot performance issues, create activity baselines, detect anomalous activity, investigate security incidents, and discover IT assets and
