Usually the Adeptia application logs, KernelApplication.log and WebrunnerApplication.log can be found here: \AdeptiaServer\ServerKernel\logs\applicationlogs.
In some cases, you may have directed the logs to be placed in a different location. To identify the location of these logs:
1) Please open \\AdeptiaServer\ServerKernel\etc\server-configure.properties file.
2) Search for "Kernel output file location" in the file and you will see the location where KernelApplication.log exists
3) Search for "Web Runner output file location" and you will see the location of WebrunnerApplication.log file.
