Information Channels and Output Directions
The system supports 10 channels. The first six channels (Channel 0 to Channel 5) have default
channel names and are associated with six default output directions. For devices equipped with
storage media, log information is output to log files through Channel 9 by default. That is, seven
total default output directions are supported.
For details of the association relationship between default channels and output directions, see
