Configuring the Syslog service
A
Syntax: show logging
The Syslog display shows the following configuration information, in the rows above the log entries
themselves.
Static and dynamic buffers
The software provides two separate buffers:
•
Static – logs power supply failures, fan failures, and temperature warning or shutdown
messages
•
Dynamic – logs all other message types
In the static log, new messages replace older ones, so only the most recent message is displayed.
For example, only the most recent temperature warning message will be present in the log. If
multiple temperature warning messages are sent to the log, the latest one replaces the previous
one. The static buffer is not configurable.
The message types that appear in the static buffer do not appear in the dynamic buffer. The
dynamic buffer contains up to the maximum number of messages configured for the buffer (50 by
default), then begins removing the oldest messages (at the bottom of the log) to make room for
new ones.
TABLE 221 CLI display of Syslog buffer configuration
This field... Displays...
Syslog logging The state (enabled or disabled) of the Syslog buffer.
messages dropped The number of Syslog messages dropped due to user-configured filters.
By default, the software logs messages for all Syslog levels. You can
disable individual Syslog levels, in which case the software filters out
messages at those levels. Refer to
“Disabling logging of a message
level” on page 1278. Each time the software filters out a Syslog
message, this counter is incremented.
flushes The number of times the Syslog buffer has been cleared by the clear
logging command. Refer to
“Clearing the Syslog messages from the local
buffer” on page 1281.
overruns The number of times the dynamic log buffer has filled up and been
cleared to hold new entries. For example, if the buffer is set for 100
entries, the 101st entry causes an overrun. After that, the 201st entry
causes a second overrun.
level The message levels that are enabled. Each letter represents a message
type and is identified by the key (level code) below the value. If you
disable logging of a message level, the code for that level is not listed.
messages logged The total number of messages that have been logged since the software
was loaded.
level code The message levels represented by the one-letter codes.
