Functions

func NewPoint

func NewPoint(name, host string, measurement senml.Measurement) (*influxdb.Point, error)

NewPoint returns an InfluxDB point for a SenML measurement.

func NewSenML

func NewSenML(row *models.Row) (m []senml.Measurement, err error)

NewSenML creates a new JSONPoint from an InfluxDB row

func PointsFromSenML

func PointsFromSenML(name, host string, list []senml.Measurement) (pts []*influxdb.Point, err error)

PointsFromSenML creates a list of InfluxDB points from a list of SenML measurements.

Types

type Client

type Client struct {
	client.Client
	Database string
	// contains filtered or unexported fields
}

Client is an extended InfluxDB client

func NewClient

func NewClient(config *ClientConfig) (c *Client, err error)

NewClient returns a Client for the given configuration

func (*Client) Query

func (c *Client) Query(name, host string, from, to time.Time, last bool) (measurements []senml.Measurement, err error)

Query builds a query based on the given parameters and returns the result as SenML.

func (*Client) Write

func (c *Client) Write(name, host string, data ...senml.Measurement) error

Write writes a series of SenML measurements to InfluxDB.

type ClientConfig

type ClientConfig struct {
	Host, Database, Username, Password string
}

ClientConfig contains InfluxDB client configuration
