Jason,
You may wish to download the Redbook SG24-6898-01, Systems Programmer's
Guide to z/IS System Logger.
Even though it has not been updated since 2012, the information may still
be relevant.
In particular, chapter 8 is performance and tuning.
That chapter mentions the IXGRPT1 report as well as a SORT job that may be
more readable.
That chapter also mentions several RMF reports of interest.
