These messages are valid, and point to a config change on the devices in question. What do you feel is missing?

If you want to customize the body of a message, you will have to use the Embedded Syslog Manager feature available in IOS 12.3(2)T and higher (more on ESM can be found at http://www.cisco.com/en/US/docs/ios/12_3t/12_3t2/feature/guide/gt_esm.html). However, you can adjust the types of messages sent by increasing the logging trap severity. For example, to send debug messages from your router (including stack traces from crashes), configure:

logging trap debug
