Functions

func EpochToTime added in v0.9.0

func EpochToTime(epoch int64, precision string) (time.Time, error)

EpochToTime takes a unix epoch time and uses precision to return back a time.Time

func SetPrecision added in v0.9.0

func SetPrecision(t time.Time, precision string) time.Time

SetPrecision will round a time to the specified precision

Types

type BatchPoints added in v0.9.0

type BatchPoints struct {
	Points          []Point           `json:"points,omitempty"`
	Database        string            `json:"database,omitempty"`
	RetentionPolicy string            `json:"retentionPolicy,omitempty"`
	Tags            map[string]string `json:"tags,omitempty"`
	Timestamp       time.Time         `json:"timestamp,omitempty"`
	Precision       string            `json:"precision,omitempty"`
}

BatchPoints is used to send batched data in a single write. Database and Points are required If no retention policy is specified, it will use the databases default retention policy. If tags are specified, they will be "merged" with all points. If a point already has that tag, it is ignored. If timestamp is specified, it will be applied to any point with an empty timestamp. Precision can be specified if the timestamp is in epoch format (integer). Valid values for Precision are n, u, ms, s, m, and h

func (*BatchPoints) UnmarshalJSON added in v0.9.0

func (bp *BatchPoints) UnmarshalJSON(b []byte) error

UnmarshalJSON decodes the data into the BatchPoints struct

type Client

type Client struct {
	// contains filtered or unexported fields
}

Client is used to make calls to the server.

func NewClient

func NewClient(c Config) (*Client, error)

NewClient will instantiate and return a connected client to issue commands to the server.

func (*Client) Addr added in v0.9.0

func (c *Client) Addr() string

Addr provides the current url as a string of the server the client is connected to.

func (*Client) Ping

func (c *Client) Ping() (time.Duration, string, error)

Ping will check to see if the server is up Ping returns how long the requeset took, the version of the server it connected to, and an error if one occured.

func (*Client) Query

func (c *Client) Query(q Query) (*Results, error)

Query sends a command to the server and returns the Results

func (*Client) Write added in v0.9.0

func (c *Client) Write(bp BatchPoints) (*Results, error)

Write takes BatchPoints and allows for writing of multiple points with defaults If successful, error is nil and Results is nil If an error occurs, Results may contain additional information if populated.

type Config added in v0.9.0

type Config struct {
	URL       url.URL
	Username  string
	Password  string
	UserAgent string
}

Config is used to specify what server to connect to. URL: The URL of the server connecting to. Username/Password are optional. They will be passed via basic auth if provided. UserAgent: If not provided, will default "InfluxDBClient",

type Point added in v0.9.0

type Point struct {
	Name      string
	Tags      map[string]string
	Timestamp time.Time
	Fields    map[string]interface{}
	Precision string
}

Point defines the fields that will be written to the database Name, Timestamp, and Fields are required Precision can be specified if the timestamp is in epoch format (integer). Valid values for Precision are n, u, ms, s, m, and h

func (*Point) MarshalJSON added in v0.9.0

func (p *Point) MarshalJSON() ([]byte, error)

MarshalJSON will format the time in RFC3339Nano Precision is also ignored as it is only used for writing, not reading Or another way to say it is we always send back in nanosecond precision

func (*Point) UnmarshalJSON added in v0.9.0

func (p *Point) UnmarshalJSON(b []byte) error

UnmarshalJSON decodes the data into the Point struct

type Query added in v0.9.0

type Query struct {
	Command  string
	Database string
}

Query is used to send a command to the server. Both Command and Database are required.

type Result added in v0.9.0

type Result struct {
	Series []influxql.Row
	Err    error
}

Result represents a resultset returned from a single statement.

func (*Result) MarshalJSON added in v0.9.0

func (r *Result) MarshalJSON() ([]byte, error)

MarshalJSON encodes the result into JSON.

func (*Result) UnmarshalJSON added in v0.9.0

func (r *Result) UnmarshalJSON(b []byte) error

UnmarshalJSON decodes the data into the Result struct

type Results

type Results struct {
	Results []Result
	Err     error
}

Results represents a list of statement results.

func (Results) Error

func (a Results) Error() error

Error returns the first error from any statement. Returns nil if no errors occurred on any statements.

func (*Results) MarshalJSON

func (r *Results) MarshalJSON() ([]byte, error)

MarshalJSON encodes the result into JSON.

func (*Results) UnmarshalJSON

func (r *Results) UnmarshalJSON(b []byte) error

UnmarshalJSON decodes the data into the Results struct
