Functions

func GetPythonVersion

func GetPythonVersion() string

GetPythonVersion returns the version string as provided by the embedded Python interpreter.

func GetStatusInformation

func GetStatusInformation() *host.InfoStat

GetStatusInformation just returns an InfoStat object, we need some additional information that's not

Types

type Meta

type Meta struct {
	SocketHostname string   `json:"socket-hostname"`
	Timezones      []string `json:"timezones"`
	SocketFqdn     string   `json:"socket-fqdn"`
	EC2Hostname    string   `json:"ec2-hostname"`
	Hostname       string   `json:"hostname"`
	HostAliases    []string `json:"host_aliases"`
	InstanceID     string   `json:"instance-id"`
}

Meta is the metadata nested under the meta key

func GetMeta

func GetMeta() *Meta

GetMeta grabs the metadata from the cache and returns it, if the cache is empty, then it queries the information directly

type Payload

type Payload struct {
	Os            string            `json:"os"`
	PythonVersion string            `json:"python"`
	SystemStats   *systemStats      `json:"systemStats"`
	Meta          *Meta             `json:"meta"`
	HostTags      *tags             `json:"host-tags"`
	ContainerMeta map[string]string `json:"container-meta,omitempty"`
}

Payload handles the JSON unmarshalling of the metadata payload

func GetPayload

func GetPayload(hostname string) *Payload

GetPayload builds a metadata payload every time is called. Some data is collected only once, some is cached, some is collected at every call.

func GetPayloadFromCache

func GetPayloadFromCache(hostname string) *Payload

GetPayloadFromCache returns the payload from the cache if it exists, otherwise it creates it. The metadata reporting should always grab it fresh. Any other uses, e.g. status, should use this
