When you enable server statistical logging for the
Database Server, a log file is created in the FileMaker Server/Data/Logs/ folder. All of the values that you see on the Statistics > Server tab in Admin Console are timestamped and written to a file. See
Viewing server statistics.
You can view these server statistics by opening the Stats.log file in any application that can read tab-delimited data (FileMaker Pro or a text editor) or the Console application (OS X).
To configure statistics logging, see
Logging and statistics settings.
