toUInt() function
The toUInt() function converts all values in the _value column to UIntegers.
Function type: Type conversion
toUInt()
Supported data types: Boolean | Duration | Float | Integer | Numeric String | Time
For duration and time values, toUint() returns the following:
| Input type | Returned value |
|---|---|
| Duration | The number of nanoseconds in the specified duration |
| Time | A nanosecond epoch timestamp |
To convert values in a column other than _value, define a custom function
patterned after the function definition,
but replace _value with your desired column.
Examples
from(bucket: "telegraf")
|> filter(fn:(r) =>
r._measurement == "mem" and
r._field == "used"
)
|> toUInt()
Function definition
toUInt = (tables=<-) =>
tables
|> map(fn:(r) => ({ r with _value: uint(v:r._value) }))
