OpManager has default device templates specific to numerous different vendors. These device templates are regularly updated with new templates and enhancements are made to the existing templates for improved usability.
A device template is a set of predefined properties such as device type, vendor, monitors and monitoring intervals that are defined for a device. It lets you automatically classify and associate monitors across multiple devices at once and effectively check and track the necessary statistics. Each device template is associated with a unique SysOID that helps in proper classification of the device.
If the specific SysOID based templates are not available in OpManager, the discovered device will be classified as 'Unknown'. In such cases, the Sync and Rediscover option helps you fetch new device templates from OpManager's shared repository and properly sync the devices with their respective device templates.
