246 ExtremeWare XOS 10.1 Command Reference Guide
Commands for Status Monitoring and Statistics
Events, Components, and Subcomponents. As mentioned, a single event can be included or
excluded by specifying the events name. Multiple events can be added or removed by specifying an
ExtremeWare XOS component name plus an optional severity. Some components, such as BGP, contain
subcomponents, such as Keepalive, which is specified as BGP.Keepalive. Either components or
subcomponents can be specified. The keyword
all in place of a component name can be used to
indicate all ExtremeWare XOS components.
Severity Levels. When an individual event name is specified following the events keyword, no
severity value is needed since each event has pre-assigned severity. When a component, subcomponent,
or the
all keyword is specified following the events keyword, a severity value is optional. If no
severity is specified, the severity used for each applicable subcomponent is obtained from the
pre-assigned severity threshold levels for those subcomponents. For example, if STP were specified as
the component, and no severity is specified for the add of an include item, then only messages with
severity of
error and greater would be passed, since the threshold severity for the STP component is
error. If STP.InBPDU were specified as the component, and no severity is specified, then only messages
with severity of
warning and greater would be passed, since the threshold severity for the STP.InPBDU
subcomponent is
warning. Use the show log components command to see this information.
The severity keyword all can be used as a convenience when delete or exclude is specified. The use
of
delete (or exclude) with severity all deletes (or excludes) previously added events of the same
component of all severity values.
NOTE
If no severity is specified when delete or exclude is specified, severity all is used
If the only keyword is present following the severity value, then only the events in the specified
component at that exact severity are included. Without the
only keyword, events in the specified
component at that severity or more urgent are included. For example, using the option
severity
warning
implies critical, error, or warning events, whereas the option severity warning only implies
warning events only. Severity
all only is not a valid choice.
Any EMS events with severity debug-summary, debug-verbose, or debug-data will not be logged
unless debug mode is enabled
Filter Optimization. Each time a configure log filter command is issued for a given filter name,
the events specified are compared against the current configuration of the filter to try to logically
simplify the configuration.
For example, if the command:
configure log filter bgpFilter1 add events bgp.keepalive severity error only
were to be followed by the command:
configure log filter bgpFilter1 add events bgp severity info
the filter item in the first command is automatically deleted since all events in the BGP.Keepalive
subcomponent at severity
error would be also included as part of the second command, making the
first command redundant.
More Information. See the command show log on page 283 for more information about severity
levels.
