Log

You can see various logs 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.

log name log description
apache2 It is the apache2 access log.
dhcpv4 It is the logs that were generated in real-time during the runtime of the dhcpv4 service.
dhcpv6 It is the logs that were generated in real-time during the runtime of the dhcpv6 service.
failover It is the logs that were generated in real-time during the runtime of the failover service.

Display logs

LYSH@MyHostName# show log apache2		// Display all apache2 logs
LYSH@MyHostName# show log radius		// Display all radius logs

Display last n logs

LYSH@MyHostName# show log apache2 -n 10		// Display only the last 10 apache2 logs
LYSH@MyHostName# show log radius -n 10		// Display only the last 10 radius logs

Display last n logs with keyword

LYSH@MyHostName# show log apache2 -n 10	request	// Display only the last 10 apache2 logs filtered by "request" 
LYSH@MyHostName# show log radius -n 10	accept	// Display only the last 10 radius logs filtered by "request"

Display logs in real-time

LYSH@MyHostName# show log apache2 -w		// Display the apache2 logs in real-time
LYSH@MyHostName# show log radius -w		// Display the radius logs in real-time

Display logs in real-time with keyword

LYSH@MyHostName# show log apache2 -w request	// Display the apache2 logs filtered by "request" in real-time
LYSH@MyHostName# show log radius -w accept	// Display the radius logs filtered by "accept" in real-time

keyword

The & is the Logical AND operator and the | is the Logical OR operator. 

LYSH@MyHostName# show log request&reply		// Display the apache2 logs having both "request" and "reply"
LYSH@MyHostName# show log request|reply		// Display the apache2 logs having either "request" or "reply"
