You can find logs for the Apache server that runs BlueCat Gateway in the /logs directory inside the container. To export the logs outside the container, you can map this location to a writable directory on the host machine.
All the log messages sent out by BlueCat Gateway and exception messages for when BlueCat Gateway crashes, are captured in the messages.log file. Over time the messages.log file can grow quickly in size so BlueCat recommends periodically backing up and clearing logs.
access.log captures all requests made to Apache and should also be cleared periodically.
