Syslog logging: enabled (0 messages dropped, 0 flushes, 0 overruns)
Buffer logging: level ACDMEINW, 3 messages logged
level code: A=alert C=critical D=debugging M=emergency E=error
I=informational N=notification W=warning
Static Log Buffer:
Dec 15 19:04:14:A:Fan 1, fan on right connector, failed
Dynamic Log Buffer (50 entries):
Dec 15 18:46:17:I:Interface ethernet4, state up
Dec 15 18:45:21:I:Bridge topology change, vlan 4095, interface 4, changed
state to forwarding

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
Table 10.3: 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. See “Disabling Logging of a
Message Level” on page 10-16. 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 or equivalent Web management interface option.
See “Clearing the Syslog Messages from the Local Buffer” on
page 10-21.
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.
