A Sybase CEP Server log file is generated every time the Sybase CEP Server is stopped and then restarted. If Sybase CEP Server or Sybase CEP Studio does not start properly, check the Sybase CEP Server log.
The latest log file is called server.log; older logs are saved as server1.log, server2.log, and so on.
The default location of the log files on Microsoft Windows is C:\sybase\SybaseC8\Server\logs
The default location of the log files on UNIX-like operating systems is located under the following subdirectory of the c8 installation directory: SybaseC8/server/logs.
