Point

A single data point in a time series.

JSON representation 
{
  "interval": {
    object (TimeInterval)
  },
  "value": {
    object (TypedValue)
  }
}
Fields
interval

object (TimeInterval)

The time interval to which the data point applies. For GAUGE metrics, the start time is optional, but if it is supplied, it must equal the end time. For DELTA metrics, the start and end time should specify a non-zero interval, with subsequent points specifying contiguous and non-overlapping intervals. For CUMULATIVE metrics, the start and end time should specify a non-zero interval, with subsequent points specifying the same start time and increasing end times, until an event resets the cumulative value to zero and sets a new start time for the following points.
value

object (TypedValue)

The value of the data point.

TimeInterval

A time interval extending just after a start time through an end time. If the start time is the same as the end time, then the interval represents a single point in time.

JSON representation 
{
  "endTime": string,
  "startTime": string
}
Fields
endTime

string (Timestamp format)

Required. The end of the time interval.

Uses RFC 3339, where generated output will always be Z-normalized and uses 0, 3, 6 or 9 fractional digits. Offsets other than "Z" are also accepted. Examples: "2014-10-02T15:01:23Z", "2014-10-02T15:01:23.045123456Z" or "2014-10-02T15:01:23+05:30".
startTime

string (Timestamp format)

Optional. The beginning of the time interval. The default value for the start time is the end time. The start time must not be later than the end time.

Uses RFC 3339, where generated output will always be Z-normalized and uses 0, 3, 6 or 9 fractional digits. Offsets other than "Z" are also accepted. Examples: "2014-10-02T15:01:23Z", "2014-10-02T15:01:23.045123456Z" or "2014-10-02T15:01:23+05:30".

TypedValue

A single strongly-typed value.

JSON representation 
{

  // Union field value can be only one of the following:
  "boolValue": boolean,
  "int64Value": string,
  "doubleValue": number,
  "stringValue": string,
  "distributionValue": {
    object (Distribution)
  }
  // End of list of possible types for union field value.
}
Fields
Union field value. The typed value field. value can be only one of the following:
boolValue

boolean

A Boolean value: true or false.
int64Value

string (int64 format)

A 64-bit integer. Its range is approximately ±9.2x1018.
doubleValue

number

A 64-bit double-precision floating-point number. Its magnitude is approximately ±10±300 and it has 16 significant digits of precision.
stringValue

string

A variable-length string value.
distributionValue

object (Distribution)

A distribution value.
