Cisco show log number of messages












5















When I run the "show log" command, it displays the latest 360 messages.



Why 360?



Can this value by changed?



If yes, what is the command for that?



Thanks.

If you’re using ‘show log’ to display messages in the logging buffer, then you’re using IOS or IOS-XE.



In both of those Cisco operating systems there is a default syslog buffer size (configured in bytes). It happens that you can currently fit 360 messages in that buffer.



You can change the log buffer size to be much larger with: “logging buffered 15000000 debugging”; that command will make your log buffer about 15MB, and will accept log messages at the debug level or higher.



Warning changing your log buffer size will flush the current log buffer.

The command show log will always display the full log of the switch/router. Your unit is probably set to the default logging buffer, which is 4096 bytes.



You can change the logging buffer in config mode, by using logging buffered <bytes to log>. We typically use logging buffered 96000 on our switches, which increases the logging buffer to 96 kb instead of the default 4 kb.



A little trick:



If you have a very large log, it can be a bit frustrating looking through months of log before you reach the day in which you think is important. Example log:

Now if you only want to see the log from January 10, you can use the command



show log | be Jan 10



This will yield:

On the Cisco Nexus platform, you can use the command show log last 50 to see the last 50 log entries.

If you’re using ‘show log’ to display messages in the logging buffer, then you’re using IOS or IOS-XE.



In both of those Cisco operating systems there is a default syslog buffer size (configured in bytes). It happens that you can currently fit 360 messages in that buffer.



You can change the log buffer size to be much larger with: “logging buffered 15000000 debugging”; that command will make your log buffer about 15MB, and will accept log messages at the debug level or higher.



Warning changing your log buffer size will flush the current log buffer.

On the Cisco Nexus platform, you can use the command show log last 50 to see the last 50 log entries.

  • Hello Cown, thank you for the advised value 96000 and the command to see the logs of a given day. Very useful.

The command show log will always display the full log of the switch/router. Your unit is probably set to the default logging buffer, which is 4096 bytes.



You can change the logging buffer in config mode, by using logging buffered <bytes to log>. We typically use logging buffered 96000 on our switches, which increases the logging buffer to 96 kb instead of the default 4 kb.



A little trick:



If you have a very large log, it can be a bit frustrating looking through months of log before you reach the day in which you think is important. Example log:

  • Hello Cown, thank you for the advised value 96000 and the command to see the logs of a given day. Very useful.

The command show log will always display the full log of the switch/router. Your unit is probably set to the default logging buffer, which is 4096 bytes.



You can change the logging buffer in config mode, by using logging buffered <bytes to log>. We typically use logging buffered 96000 on our switches, which increases the logging buffer to 96 kb instead of the default 4 kb.



A little trick:



If you have a very large log, it can be a bit frustrating looking through months of log before you reach the day in which you think is important. Example log:

Now if you only want to see the log from January 10, you can use the command



show log | be Jan 10



This will yield:
