Answer:
SNMP
Step-by-step explanation:
The SNMP protocol is used by network administrators to gather information about several network devices on a given network. You need an SNMP server and each device on the network, e.g., router, switch, server, workstation, printer, etc. must be configured to report things like CPU utilization, up time, down time, etc. to the server to provide a history of the health of the overall network and each node within it to help them troubleshoot issues or to find root causes to problems.
