A computer-implemented method for supervising data stream storage including communicating with a probe that captures network data and outputs a plurality of data streams to a plurality of data repository units, receiving registration data associated with respective data streams that identifies the associated probes, selecting at least one of the data repository units to store the first data stream in real time based on a storage capacity of the data repository units to receive and store data, determining that storage capacity is not sufficient for the data stream in response to a change in the storage capacity of the data repository units to receive and store data, determining a corrective action in response to the determination that the storage capacity is not sufficient, and notifying the probe identified in association with the first data stream about the corrective action.
