Static and dynamic buffers
The software provides a static buffer and a dynamic buffer:
•
Static – logs power supply failures, fan failures, and temperature warning or shutdown
messages
•
Dynamic – logs all other message types. The power supply messages are displayed in both
static and dynamic logs.
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.
The static and dynamic buffers are both displayed when you enter the show logging command.
PowerConnect(config)# show logging

Static Log Buffer:
Aug 27 12:42:42:A:Power Supply 6, 1st right, failed
Dynamic Log Buffer (50 lines):
Aug 27 12:19:04:I:Interface ethernet3/4, state up
Aug 27 12:19:04:I:Interface ethernet6/3, state up
Aug 27 12:19:04:I:Interface ethernet3/2, state up
TABLE 20
Syslog buffer configuration

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. 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. For information about clearing the Syslog buffer, refer to
“Static and
dynamic buffers”
on page 105.
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.
