Configuring the Syslog service
A
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. Also, an entry in the static log triggers an entry in the
dynamic log. The dynamic log buffer can store up to 3800 messages.
In either the static or dynamic log, new messages replace older ones; only the most recent
message is displayed. For example, only the most recent temperature warning message will be
present in the logs. If multiple temperature warning messages are sent to the logs, the latest one
replaces the previous one.
Contents of both the static and dynamic buffers are displayed when you issue the show logging
command.

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
on page 1386. 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
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.
