Network uptime monitoring software involves tracking key metrics that can indicate when different elements of your network are up and down and by polling your network devices at regular intervals, typically using either Windows Management Instrumentation (WMI) or Simple Network Management Protocol (SNMP, to determine when a node is down.
Uptime is typically measured on a scale from 1 to 100 percent, where the higher your uptime number is, the more often your device is available and functioning correctly.
Network uptime monitoring is defined as the process of determining how often the various elements of your network are working (up) or not working (down).
