Log destinations
The system outputs logs to the following destinations: console, monitor terminal, log buffer, log host, and
log file. Log output destinations are independent and you can configure them after enabling the
information center.
Default output rules for logs
A log output rule specifies the source modules and severity level of logs that can be output to a
destination. Logs matching the output rule are output to the destination. Table 7 shows the default log
output rules.
Table 7 Default output rules
Destination Log source modules Output switch Severity
Console All supported modules Enabled Debug
Monitor terminal All supported modules Disabled Debug
Log host All supported modules Enabled Informational
Log buffer All supported modules Enabled Informational
Log file All supported modules Enabled Informational
Default output rules for diagnostic logs
Diagnostic logs can only be output to the diagnostic log file, and cannot be filtered by source modules
and severity levels. Table 8 shows the default output rule for diagnostic logs.
