Variables

var (

	// SampleData contains sample utilization data useful for testing.
	SampleData = Data{
		MetadataVersion:   metadataVersion,
		LogicalProcessors: &sampleLogicProc,
		RAMMiB:            &sampleRAMMib,
		Hostname:          "my-hostname",

Types

type Config

type Config struct {
	DetectAWS         bool
	DetectAzure       bool
	DetectGCP         bool
	DetectPCF         bool
	DetectDocker      bool
	DetectKubernetes  bool
	LogicalProcessors int
	TotalRAMMIB       int
	BillingHostname   string
}

Config controls the behavior of utilization information capture.

type Data

type Data struct {
	MetadataVersion int `json:"metadata_version"`
	// Although `runtime.NumCPU()` will never fail, this field is a pointer
	// to facilitate the cross agent tests.
	LogicalProcessors *int      `json:"logical_processors"`
	RAMMiB            *uint64   `json:"total_ram_mib"`
	Hostname          string    `json:"hostname"`
	FullHostname      string    `json:"full_hostname,omitempty"`
	Addresses         []string  `json:"ip_address,omitempty"`
	BootID            string    `json:"boot_id,omitempty"`
	Config            *override `json:"config,omitempty"`
	Vendors           *vendors  `json:"vendors,omitempty"`
}

Data contains utilization system information.

func Gather

func Gather(config Config, lg logger.Logger) *Data

Gather gathers system utilization data.
