Types ¶
type MonitorFormatter ¶
type MonitorFormatter struct {
EventTypes monitorAPI.MessageTypeFilter
FromSource Uint16Flags
ToDst Uint16Flags
Related Uint16Flags
Hex bool
JSONOutput bool
Verbosity monitorAPI.Verbosity
Numeric bool
// contains filtered or unexported fields
}
MonitorFormatter filters and formats monitor messages from a buffer.
func NewMonitorFormatter ¶
func NewMonitorFormatter(verbosity monitorAPI.Verbosity, linkMonitor getters.LinkGetter, w io.Writer) *MonitorFormatter
NewMonitorFormatter returns a new formatter with default configuration.
func (*MonitorFormatter) FormatEvent ¶
func (m *MonitorFormatter) FormatEvent(pl *payload.Payload) bool
FormatEvent formats an event from the specified payload
Returns true if the event was successfully recognized, false otherwise.
func (*MonitorFormatter) FormatLostEvent ¶ added in v1.19.0
func (m *MonitorFormatter) FormatLostEvent(lost uint64, cpu int)
FormatLostEvent formats a lost event using the specified payload parameters.
func (*MonitorFormatter) FormatSample ¶
func (m *MonitorFormatter) FormatSample(data []byte, cpu int)
FormatSample prints an event from the provided raw data slice to stdout.
For most monitor event types, 'data' corresponds to the 'data' field in bpf.PerfEventSample. Exceptions are MessageTypeAccessLog and MessageTypeAgent.
func (*MonitorFormatter) FormatUnknownEvent ¶ added in v1.19.0
func (m *MonitorFormatter) FormatUnknownEvent(lost uint64, cpu int, t int)
FormatUnknownEvent formats an unknown event using the specified payload parameters.
type Uint16Flags ¶
type Uint16Flags []uint16
Uint16Flags is a slice of unsigned 16-bit ints with some convenience methods.
func (*Uint16Flags) Has ¶
func (i *Uint16Flags) Has(value uint16) bool
Has returns true of value exist
func (*Uint16Flags) Set ¶
func (i *Uint16Flags) Set(value string) error
Set converts the specified value into an integer and appends it to the flags. Returns an error if the value cannot be converted to a 16-bit unsigned value.
func (*Uint16Flags) String ¶
func (i *Uint16Flags) String() string
String provides a human-readable string format of the received variable.
func (*Uint16Flags) Type ¶
func (i *Uint16Flags) Type() string
Type returns a human-readable string representing the type of the receiver.
