A computer implemented method and system for simulating the effect of one or more flow specification rules upon archived network flow data. Archived network flow data is retrieved from a database that was exported from a network device. One or more flow specification rules are applied to the archived network flow data, wherein the one or more flow specification rules are configured to perform one or more flow specification actions on the archived network flow data. Determined are one or more flow actions affected on the archived network flow data by the applied one or more flow specification rules. Indication/notification of the determined one or more flow actions are provided.

System and method for determining flow specification efficacy

A computer-implemented method of grouping network traffic metadata includes, based on a selected dimension of the network traffic metadata received from a network router, obtaining a statistic about a flow of network traffic metadata received over an interval for each instance of multiple instances of the dimension. The method further includes distributing the network traffic metadata into a plurality of groups for network traffic metadata from the smallest possible number of instances of the selected dimension to be distributed to each group, with the flow of network traffic metadata distributed optimally for a criteria regarding the statistic amongst the plurality of groups for minimizing cardinality of each group of the plurality of groups with respect to unselected dimensions of the network traffic metadata and providing each group to a columnar database for storage of the network traffic metadata distributed into each group in a different partition of the columnar database.
