Types

type CompositeMonitor

type CompositeMonitor interface {
	// Start() is not reentrant!
	Start() error

	// Just a helper getter.
	StartCommand() *command.StartMonitor

	SignalTargetApp(s os.Signal)

	Cancel()

	// Done() is reentrant. Every invocation returns the same instance of the channel.
	Done() <-chan struct{}

	// Errors() method is a way to communicate non-fatal monitor's error
	// conditions back to the caller. The method is reentrant. Every invocation
	// returns the same instance of the channel. The error channel is never closed,
	// but ideally it should stop returning eny errors after the monitor is done
	// (the actual behavior might differ due to the subordinate monitors, especially
	// the one at pkg/monitors/ptrace).
	Errors() <-chan error

	// Helper method to read left-over non-critical error events after the monitor
	// is done.
	DrainErrors() []error

	Status() (*CompositeReport, error)
}
