Events Package

Use this Flux Package to calculate the time between a record and the next record. The function events.duration peeks at the next record and calculates the duration an between records and associates it with the start of the event. For the final record it can be compared against a stop column or a timestamp. This function differs to existing elapsed which removes the first entry and stateDuration which totalized on a function.

See also

events.duration

duration calculates the duration of the event.

Name Type Description
unit duration Units of state duration 'ns', 'us', 'µs', 'ms', 's', 'm', 'h'
columnName string The name of the result column. Default duration
timeColumn string The name of the time column, default _time
stopColumn string The name of the stop column, default _stop
stop time Optional. If provided, it will be used instead of the stop column

Basic Example:

import "contrib/tomhollingworth/events"

from(bucket: "example-bucket")
    |> range(start: -24h)
    |> events.duration()
Last Record Duration

The last record needs a time to compare to. The following strategy is implemented:

  • Use stop if provided.
  • If no stop time is provided, then use the value from the stopColumn column on the last record.
  • If no stopColumn is provided then use _stop by default.
Comparison to other functions

Consider the following dataset of a door opening and closing:

import "csv"

inData = "
#datatype,string,long,dateTime:RFC3339,string,string
#group,false,true,false,false,false
#default,,,,,
,result,table,_time,_value,_field
,,0,2020-01-01T08:00:00Z,Closed,value
,,0,2020-01-01T08:15:00Z,Open,value
,,0,2020-01-01T08:15:08Z,Closed,value
,,0,2020-01-01T08:21:00Z,Open,value
,,0,2020-01-01T08:21:07Z,Closed,value
,,0,2020-01-01T08:24:00Z,Open,value
,,0,2020-01-01T08:24:12Z,Closed,value
"

csv.from(csv: inData)
  |> range(start: 2020-01-01T08:00:00Z, stop: 2020-01-01T08:30:00Z)

|> elapsed() yields the following. The first record is dropped and durations are associated with subsequent records. Totalizing on filter on value and summing the elapsed column would have the duration swapped between open and closed.

|> stateDuration(fn: (r) => true) yields the following. The duration is continuously totalized. For a particular state we could also include that in our stateDuration function, however time is counted twice on subsequent events. Totalizing this would have that time counted twice.
