Top call statistics log

When you enable the Top Call Statistics setting on the Logs > Log Settings tab, the TopCallStats.log file is created in the FileMaker Server/Logs/ folder. See Using log settings.

The TopCallStats.log can help identify performance issues with hosted databases, but the logging process may negatively impact server performance. Disable this setting when you no longer need detailed information about the client request operations. When you disable this setting, the TopCallStats.log is no longer updated, and server performance may improve.

To enable top call statistics:

  • In Log Settings, set Top Call Statistics to Enabled.

TopCallStats.log describes the client requests (up to 25) that have the longest elapsed time during the statistics collection interval.

Notes 

  • You can view top call statistics by opening the TopCallStats.log file in any application that can read tab-delimited data.

  • When the size of the TopCallStats.log file reaches the log file size limit, it is renamed TopCallStats-old.log and a new TopCallStats.log file is created.
