|
It's easy to report on SMF 99 data! | |
Spectrum SMF Writer handles the difficult SMF record parsing for you automatically. You just specify which fields you want to see. Spectrum SMF Writer also converts the arcane date and time fields and reformats them into an attractive report. Plus, Spectrum SMF Writer can export SMF data as comma delimited files to use on your PC.
