Types

type Benchmark

type Benchmark interface {

	// Get benchmark's name
	Name() string

	// Do a test warmup
	Warmup() error

	// Cleanup after the test
	Cleanup() error

	// Run the test, return the cumulative statistics after the whole run
	Run(duration time.Duration, seed uint64) (interface{}, error)

	// Gather current snapshot of probes
	// This should be delta since the previous probe - e.g. req/sec that happened
	// between this and previous run.
	// It will be called in parallel while the `Run` call is still ongoing
	Probe() interface{}
}

type HWStats

type HWStats struct {
	CPUTime               float64 `json:"cpuTime"`               // Total about of CPU time used by the process in seconds
	CPUKernelTimeFraction float64 `json:"cpuTimeKernelFraction"` // Fraction of the total CPU time that was spent on the kernel side
	VMM                   uint64  `json:"vmm"`                   // Virtual memory used
	RSS                   uint64  `json:"rss"`                   // Resident memory used
	IOBytesRead           uint64  `json:"ioBytesRead"`           // Number of bytes read
	IOBytesWrite          uint64  `json:"ioBytesWrite"`          // Number of bytes written
	IOCallsRead           uint64  `json:"ioCallsRead"`           // Number of io read syscalls
	IOCallsWrite          uint64  `json:"ioCallsWrite"`          // Number of io write syscalls
