When you specify a severity level, messages of that severity level and greater are sent to the
target. If you want only those 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 to the target, but specifying
severity warning only sends only warning
messages.
You can also use the following command to configure severity levels, which associate a filter
with a target:
configure log target [console | memory-buffer | primary-msm | primary-node |
backup-msm | backup-node | nvram | session | syslog [all | <ipaddress> |
<ipPort> {vr <vr_name>} [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 that target. The filter may allow only certain categories of messages
to pass. Only the messages that pass the filter and then pass the specified severity level
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 described in
Filtering By Components and Conditions on page 220.
Components and Conditions
The event conditions detected by XCM8800 are organized into components and
subcomponents. To get a listing of the components and subcomponents in your release of
XCM8800, use the following command:
show log components {<event component>} {version}
For example, to get a list of the components and subcomponents in your system, use the
following command:
show log components
The following is partial output from this command:
Severity

The display above lists the components, subcomponents, and the severity threshold
assigned to each. In EMS, you use a period (.) to separate component, subcomponent, and
