Adapter logs capture information about the adapter currently processing. The amount of detail that the log captures depends upon the logging level of the logging you have set. Adapter logs are useful for debugging problems and watching the adapter process progress.
Each adapter has its own log file, path, and log level. You specify these values in the Logging section of the Synchronization Policy for the appropriate user type (Identity Manager or Service Provider).
Delete Adapter logs only when the adapter has been stopped. In most cases, it is a good practice to make a copy of an adapter log for archive purposes before you delete the log.
