1. An automated subsystem of a computer system, the automated subsystem comprising:

  • one or more processors;

    one or more memories;

    one or more mass-storage devices; and

    computer instructions stored in one or more of the one or more memories that, when retrieved from memory and executed by one or more of the one or more processors, control the automated subsystem toidentify time-ordered metric-value data stored within the computer system,partition a total time spanning the earliest-in-time metric value to the latest-in-time metric value into multiple time intervals,for each time interval, transform the metric-value data associated with times within the time interval from the time domain to the frequency domain to generate corresponding frequency-domain data for the time interval,assemble the frequency-domain data for the multiple time intervals into a metric surface within a frequency-amplitude-time space, andstore, in one or more of the one or more memories and mass-storage devices, a representation of the metric surface in association with an indication of a metric with respect to which the time-ordered metric-value data was generated.
