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.
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 A-9. 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 A-
10.
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.
