a udf (batch) for kapacitor using prophet

facebook prophet doc
main thread on influxdata community

it's a unix socket based udf.
by default it use /tmp/udf_prophet.sock , make sure you give enough read/write right for kapacitor daemon/process to interact with the file.
you can override the file location as the first argument running this script.
(i was able to use run it on docker and/or kubernetes)

Inspired by this talk, by the creator of kapacitor.

InfluxDb support by default holt_winters for forecasting timeseries.
Note that you need to specify the seasonality pattern to forecast with holt_winters, without the right seasonality pattern your forcasted value may endup being not that usefull.
HOLT_WINTERS()
Finding the seasonality pattern of a timeseries is not that easy ! :).
Prophet on the other hand try to find the seasonal pattern it self, and is pretty good a it.

Using it with a system like kapacitor make sense, since you timeseries and seasonality pattern may change in the future.
And unless you have enough time/people to track those change, you had rather have something else doing it for you !

another nice article about forecasting jobs, if you are curious!
