I would like to fit an ARIMA model to my data with a search something like this:
<base search>| timechart span=5m avg(value) as value by some_field
The problem here is that, the number of field that returns by this search is dynamic, so it can return 5 fields one day but it could also return 3 or 7 the other day for instance.
I would like to fit an ARIMA model to all the fields that is returned by that search. What I found was the foreach command where you iterate over fields :
| foreach * [eval '<<FIELD>>' = ... ]
However, when I try to use the fit command instead of eval, I get an error message saying:
Error in 'foreach' command: Search pipeline may not contain non-streaming commands
Since foreach cannot contain non-streaming commands.
Is there a way to come around this issue?
