Options range from flat files (for debugging) to time-series databases like , InfluxDB , or Elasticsearch . Many commercial collectors use proprietary columnar stores optimized for time-based range queries.
: Consolidates individual packets into "flows"—conversations defined by source/destination IPs, ports, and protocols—to reduce the volume of data while maintaining visibility.
