In the Monitoring → Discovery section results of network discovery are shown. Discovered devices are sorted by the discovery rule.
If a device is already monitored, the host name will be listed in the Monitored host column, and the duration of the device being discovered or lost after previous discovery is shown in the Uptime/Downtime column.
After that follow the columns showing the state of individual services for each discovered device. A tooltip for each cell will show individual service uptime or downtime.
