A computer-based method includes receiving, at a compute device, a collected set of system measurement facility (SMF) data from a mainframe operating system. The method includes, retrieving from a memory operatively coupled to the compute device, a set of SMF field-type identifiers. Each SMF field-type identifier having a one-to-one logical relation with a conditional value from a set of conditional values. The method includes selecting SMF field values from the collected set of SMF data, based on the set of conditional values. The SMF field values is a subset of SMF field values included in the collected set of SMF data. The method further includes executing a flattening process to produce a flattened record that includes at least one flattened SMF field value converted into a target format, and inserting the flattened record into a data repository compatible with the target format.
