Hello All. I'm trying to see what the logging buffer size is for a WLC running code 8.3.140. In the GUI it shows the syslog level is: Informational and the Buffered Log Level is: Notifications. If I use the command show logging, it shows me the following under Logging to buffer:
Logging to buffer :
- Logging of system messages to buffer :
- Logging filter level.......................... notifications
- Number of system messages logged.............. 24109923
- Number of system messages dropped.............
- Number of Messages dropped due to Facility .... 069427385
Warning: Output is too long and has been truncated
--More-- or (q)uit
- Logging of debug messages to buffer ........... Disabled
- Number of debug messages logged............... 0
- Number of debug messages dropped.............. 0
- Cache of logging ............................. Disabled
- Cache of logging time(mins) ................... 10080
- Number of over cache time log dropped ........ 0
So how would I see what the size is set to for the logging buffer? Thanks.

it is not saved in nvram like other network devices it is saved on disk
basically the log size can be as large as the free disk space !
(not correct)
Maximum 256 message logs are stored locally (FIFO). Use external syslog server!
How to use External syslog server: see this document.

and it can be changed using the logging history size global configuration command
System Management Configuration Guide, Cisco IOS XE Release 3SE (Cisco WLC 5700 Series)
When the history table is full (it contains the maximum number of message entries specified with the logging history size global configuration command),
Feature |
Default Setting |
---|---|
System message logging to the console |
Enabled. |
Console severity |
Debugging. |
Logging file configuration |
No filename specified. |
Logging buffer size |
4096 bytes. |

Thanks for the response. Do you know how would I verify that only 256 logs are stored locally? I looked in the GUI under Management-->Logs-->Message Logs and I copied it to Notepad and had 368 lines. If I do show logging and get the logs to Notepad I counted 1721 lines. I also did an upload of the config from the controller and only found this in the config
config logging traceinfo disable emergencies
config logging buffered notifications
config logging buffered 5
config logging syslog level informational
config logging syslog level 6
config logging syslog host 1.1.1.1
config logging syslog facility local6
