Simple Network Management Protocol (SNMP) is used to get information about the current status of servers, network equipment, printers or other IP devices. You can get different metrics through SNMP: CPU utilization, number of processes, state of services, etc. The major SNMP advantages are that it is supported by almost any devices and doesn’t require a separate monitoring system agent to be installed.
