Log

You can see various logs that are located in each device using the show log command.

LYSH@MyHostName# show log {name} [-h] [-n NUMBER] [-w] [keyword]
optional arguments:
  -h, --help                      show this help message and exit
  -n [NUMBER], --number [NUMBER]  enter 0 to show all logs, and enter a value greater than 0 to show as much as the value entered
  -w, --watch                     show the log or setup status in real time

The below table shows you all kinds of logs. Some logs are generated in real-time during the runtime of a specific service, which is called "Runtime log".

If the Runtime log of a specific service is disabled, logs are not generated. Therefore, you should verify the status of the Runtime log by the show service command. If disabled, you need to enable it.
