Enumeration Case


Default-level messages are initially stored in memory buffers. Without a configuration change, they are compressed and moved to the data store as memory buffers fill. They remain there until a storage quota is exceeded, at which point, the oldest messages are purged. Use this level to capture information about things that might result a failure. Logging a message of this type is equivalent to calling the os_log function.
