If debugging is enabled (using any debug command), and the logging buffer is configured to include
level 7 (debugging) messages, debug output will be included in the system log. Debugging output is not
formatted like system error messages and will not be preceded by the percent symbol (%).
Examples The following is sample output from the show logging command on a software image that supports the
Embedded Syslog Manager (ESM) feature:
Router# show logging

0 flushes, 0 overruns, xml disabled, filtering disabled)
Console logging: level debugging, 31 messages logged, xml disabled,
