Cisco System’s UNIX syslog format is compatible with 4.3 BSD UNIX.
Enable debug timestamps and include date, time, and milliseconds relative to the local time zone:
!
service timestamps debug datetime msec localtime show-timezone
service timestamps log datetime msec localtime show-timezone
!
Step 2
Verify that console logging is disabled. If it is enabled, the NAS will intermittently freeze up as soon as
the console port is overloaded with log messages. See the field “1 flushes.” Increments on this number
represents bad logging behavior.
