I don't see the problem. You have five messages logged to the buffer:

Nov 2 17:19:34.770: %SYS-5-CONFIG_I: Configured from console by [username] onvty2 ( [laptop_ip])

Nov 2 17:20:19.954: %SYS-5-CONFIG_I: Configured from console by [username] onvty2 ([laptop_ip])

Nov 2 17:24:08.302: %SYS-5-CONFIG_I: Configured from console by [username] onvty2 ( [laptop_ip])

Nov 2 17:24:24.142: %SYS-5-CONFIG_I: Configured from console by [username] onvty2 ([laptop_ip])

Nov 2 17:24:38.394: %SYS-5-CONFIG_I: Configured from console by [username] onvty2 ( [laptop_ip])

Nov 2 17:24:50.630: %SYS-5-CONFIG_I: Configured from console by [username] onvty2 ([laptop_ip])

What are you expecting to see?

In the example you can see me admin down an interface, this doesn't appear in the logs. Cabling was done today so interfaces and port channels were going up and down but none of that appears in the logs.

Thanks.

I missed where you downed an interface in your testing. It would be helpful to see the full show run as well as a show ver from this switch.
