Configuring the Syslog service

Static and dynamic buffers
The software provides two 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.
The static and dynamic buffers are both displayed when you display the log.
Notice that the static buffer contains two separate messages for fan failures. Each message of
each type has its own buffer. Thus, if you replace fan 1 but for some reason that fan also fails, the
software replaces the first message about the failure of fan 1 with the newer message. The
software does not overwrite the message for fan 2, unless the software sends a newer message for
fan 2.
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.
