To help you successfully manage your network, you need to identify the various devices on your network. Network Discovery lets you find new network devices, identify previously-discovered network devices that are no longer found, and find network devices whose discovery properties have changed. The discovery is performed by running tasks that discover devices and reporting the data to the Notification Server. The discovery data about devices is stored as known resources in the Configuration Management Database (CMDB). To keep your discovery data current, you configure automated discovery tasks to run at regular intervals.
You can manually create tasks from the Task Management Portal. This option lets you configure more advanced options and schedules. You can run two kinds of tasks: discovering a network or discovering an individual device.
