To display the Syslog parameters currently in effect on a NetIron MLX router, enter the following command from
any level of the CLI:
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
•
Dynamic – logs all other message types. In previous releases, power supply messages were displayed in
static logs only, with only the last event logged in. Beginning with release 03.8.00, power supply messages
are now 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.
Table 5.2: 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. 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,
see “Static and Dynamic Buffers” on page 5-5.
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.
