}

An Archive is a rollup of all resources and options needed to reproduce a test identically elsewhere.

func ReadArchive(in io.Reader) (*Archive, error)

func (*Archive) Write added in v0.15.0

type Collector added in v0.8.3 

type Collector interface {
	// Init is called between the collector's creation and the call to Run(), right after the k6
	// banner has been printed to stdout. The argument is the result of calling MakeConfig() and
	// then deserializing from JSON the config value stored to disk (if any).
	Init() error

	// MakeConfig is called before Init() and should instantiate a blank configuration struct.
	// Do not apply defaults here, instead use null'able values and apply defaults in Init().
	MakeConfig() interface{}

	// Run is called in a goroutine and starts the collector. Should commit samples to the backend
	// at regular intervals and when the context is terminated.
	Run(ctx context.Context)

	// Returns whether the collector is ready to receive samples. The engine will wait for this to
	// return true before doing anything else.
	IsReady() bool

	// Collect receives a set of samples. This method is never called concurrently, and only while
	// the context for Run() is valid, but should defer as much work as possible to Run().
	Collect(samples []stats.Sample)
}

A Collector abstracts away the details of a storage backend from the application.
