What is probing?
Probing is done during rediscovery: it is the process of requesting and receiving device configuration information by performing a complete device MIB walk (which is how DFM discovers which MIBs a device supports). This is done when a new device is added to the DFM inventory (and the device is discovered), when inventory collection is done and devices are rediscovered, or when you perform a manual rediscovery of a device element. The device configuration DFM receives during a probe is saved to the DFM inventory.
