The core workflow every other tutorial in this section builds on: getting one device from "not monitored" to reporting data and detections.
From Devices, click Add device and choose the sensor that has network access to it.
SNMP v2c or v3 covers most routers, switches and firewalls with no agent required. Use SSH for devices that only expose a CLI, and WMI for Windows hosts.
Linivo runs a live test poll before saving, so a wrong community string or credential fails immediately instead of showing up as an unreachable device an hour later.
