Network monitoring provides visibility into the various components that make up a network, ensuring that engineers can troubleshoot network issues at any layer in which they occur. In order for data to be sent across a network, it will pass through each component of the OSI, utilizing different protocols, beginning at the physical layer and ending at the application layer.
The Open Systems Interconnection (OSI) Model breaks down several functions that computer systems rely on to send and receive data.
Networks enable the transfer of information between two systems, including between two computers or applications. Data that’s sent over a network passes through each layer of the OSI.
