THE ABILITY TO READ LOG FILES directly from your Mac FileMaker Server in a specially constructed web interface could save lots of time. DataManix adds to their suite of FileMaker Server tools with just such a tool:
The FMS13 LogViewer is a FileMaker solution, that you upload to your FileMaker Server 13. It is fairly simple and works by asking the server to list all the logfiles in the web server log folder of FMS13. By selecting a logfile from the list, this solution reads the content from the logfile and display it in a webviewer, which has embedded some special code, that gives you the ability to filter the log lines in the logfile selected.
