// contains filtered or unexported fields
}
func NewLogLineProcessor ¶ added in v0.4.4

NewLogLineProcessor creates a new log line processor where it streams logs from the dmesg watcher, uses the match function, and inserts the events into the events store.
func (*LogLineProcessor) Close ¶ added in v0.4.4
func (w *LogLineProcessor) Close()
func (*LogLineProcessor) Get ¶ added in v0.4.4
func (w *LogLineProcessor) Get(ctx context.Context, since time.Time) ([]components.Event, error)
Get returns the event in the descending order of timestamp (latest event first).
type Watcher ¶ added in v0.4.0
type Watcher interface {
// Watch returns a channel that emits log lines.
// The channel is closed on (1) process exit, (2) on calling "Close" method
Watch() <-chan LogLine
