Chapter 7: Event Log and Syslog Client Commands
118
Description
Event messages are categorized into four severity levels of Critical, Major,
Minor, and Event. The severity levels are defined in the Parameters
section of this command.
You can use this command to control which of the events in the log you
want to view based on their severity levels, and so focus your efforts on
particular messages. When you specify a severity level with this
command, the LOGGING SHOW command displays the events of that
severity level and all levels above it. For example, the default setting of the
management module’s severity level is Event. At this setting, the
LOGGING SHOW command displays all of the messages in the event log,
because the Event severity is the lowest level. But if you were to set the
management module’s severity level to Major, then you would only see
the Critical and Major messages.
This command also controls the messages sent by the management
module’s syslog client to a syslog server. At the default value of Event, all
messages are sent to a syslog server. But if you set the module’s severity
to Major, then only Critical and Major messages would be sent.
The management module can have only one severity level setting. The
same setting applies to messages viewed in the event log and sent to a
syslog server.
Examples
This command sets the severity level to critical:
logging set eventlog severity-level=critical
This command sets the severity level to major:
logging set eventlog severity-level=major
