Most network monitoring solutions use IP addresses to poll the devices and fetch performance data, but some network admins might want to poll their devices using DNS names of the devices.

This setting can be controlled throughout OpManager or can also be configured for individual devices.
Go to Settings → Monitoring → Monitor settings, and select which mode you want to use to poll the devices in your network. Once you're done, click 'Save'.
