toDuration() function
toDuration()
was removed in Flux 0.37.
The toDuration()
function converts all values in the _value
column to durations.
*Function type: Type conversion*
toDuration()
*Supported data types: Integer | String | Uinteger*
duration()
assumes numeric input values are nanoseconds. String input values must use duration literal representation.
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")

r._measurement == "mem" and
r._field == "used"
