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.

141 messages were sent to the server_ip but only 5 appear in the logging buffer

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.

Solution:
6509(config)#int range g2/1 - 48
6509(config-if-range)#logging event link
6509(config-if-range)#logging event bundle
6509(config-if-range)#logging event trunk
6509(config-if-range)#logging event spanning-tree status
