You might have added more devices to your network and may therefore need to forcefully discover these devices. You can discover such devices on demand by following the steps below:
OpManager continuously monitors the availability of your entire network. It sends a ping to the monitored devices every 2 minutes and records its response. If there is no response for two consecutive pings, OpManager considers the device as unavailable. During discovery, the ping function is used to determine whether the device is reachable from the OpManager server. The number of pings and their time interval can be assigned depending on our business needs.
Note: The 'Add Credentials' option can be used to create a new credential that is supported by your device. Credentials are configured to access the device for discovery, classification (device model, category, etc.) and performance monitoring. Learn more
