Status Monitoring and Statistics
To configure the severity level of the messages sent to a target, there is more than one command that
you can use. The most direct way to set the severity level of all the sent messages is to use the following
command:
configure log target [console-display | memory-buffer | nvram | session |
syslog [<host name/ip> {: <udp-port>} [local0 ... local7]]]
filter <filter name> {severity <severity> {only}}
When you specify a severity level, messages of that severity and greater will be sent to the target. If you
want only messages of the specified severity to be sent to the target, use the keyword
only
. For
example, specifying
severity warning
will send warning, error, and critical messages, but specifying
severity warning only
will just send warning messages.
Another command that can be used to configure severity levels is the command used to associate a
filter with a target:
configure log target [console-display | memory-buffer | nvram | session |
syslog [<host name/ip> {: <udp-port>} [local0 ... local7]]]
filter <filter name> {severity <severity> {only}}
When you specify a severity level as you associate a filter with a target, you further restrict the
messages reaching the target. The filter may only allow certain categories of messages to pass. Only the
messages that pass the filter, and then pass the specified severity level will reach the target.
Finally, you can specify the severity levels of messages that reach the target by associating a filter with a
target. The filter can specify exactly which message it will pass. Constructing a filter is discussed in the
section “Filtering By Components and Conditions”.
Components and Conditions
Beginning with the introduction of EMS in release 7.1.0, the event conditions detected by ExtremeWare
were organized into components and subcomponents. This is somewhat similar to the fault log
subsystems used in previous versions. Not all conditions have been placed in the
component/subcomponent structure of EMS, but all the conditions will be moved over time into this
Warning An abnormal condition, not interfering with the normal operation of the system, has
been detected which may indicate that the system or the network in general may not
be functioning as expected.
Notice A normal but significant condition has been detected, which signals that the system is
functioning as expected.
Info (Informational) A normal but potentially interesting condition has been detected, which signals that the
system is functioning as expected and simply provides potentially detailed information
or confirmation.
Debug-Summary A condition has been detected that may interest a developer determining the reason
underlying some system behavior.
Debug-Verbose A condition has been detected that may interest a developer analyzing some system
behavior at a more verbose level than provided by the debug summary information.
Debug-Data A condition has been detected that may interest a developer inspecting the data
underlying some system behavior.
1. In ExtremeWare version 7.1.0, the levels alert and emergency were deprecated. The equivalent level is critical.
