# @trace-event-get-state:
|
|
#
|
|
# Query the state of events.
|
|
#
|
|
# @name: Event name pattern (case-sensitive glob).
|
|
# @vcpu: The vCPU to query (any by default; since 2.7).
|
|
#
|
|
# Returns: a list of @TraceEventInfo for the matching events
|
|
#
|
|
# An event is returned if:
|
|
#
|
|
# - its name matches the @name pattern, and
|
|
# - if @vcpu is given, the event has the "vcpu" property.
|
|
#
|
|
# Therefore, if @vcpu is given, the operation will only match per-vCPU events,
|
|
# returning their state on the specified vCPU. Special case: if @name is an
|
|
# exact match, @vcpu is given and the event does not have the "vcpu" property,
|
|
# an error is returned.
