A server group of a data intake and query system (DIQS) establishes connections with multiple source data network nodes. Data from the multiple sources comports with a variety of different data modes and may be received via the established network connections on a periodic or continuous basis for ongoing capture as modal entries of modal buckets of a common networked storage volume. Rates of data reception across the network connections influences a process to maintain a measured utilization of storage volume capacity at, near, or below a targeted level.
