That sounds like GTFPARS. It used to read a GTF trace and generate IEHLIST for the volumes it found. It used to generate a kewl seek histogram, and a dataset seek activity report you could use to tune the location of your busiest datasets.
I used to tune SYSRES dataset positions using this, but the first 3880-23 invalidated the report as it was showing datasets with the highest cache hit rates also had the highest seek counts - considered it broken once we started buying all 3990-3.
