Simple Network Management Protocol (SNMP) is a protocol used for managing and monitoring devices on a network. SNMP allows network administrators to collect information and data from SNMP-enabled devices, such as routers, switches, servers, printers, and even some Internet of Things (IoT) devices. It provides a standardized way to access and manage network devices, enabling administrators to monitor network performance, detect and diagnose network issues, and take proactive measures to optimize performance and reliability. SNMP uses a combination of software agents and management systems to gather and transfer data, and it is commonly used in enterprise networks, data centers, and large-scale industrial systems.
