Hello,
I want to use Kapacitor in order to do more complex computation on my data.
I create a task with the type batch. I put 2 queries in to variable
forecasteec and real . I want to compute a type of error which is:
error = sum( abs( real - forecasteec))/sum(real)
The sum is for one day. The first part is easy. But I do not know how do
the sum on 1 day. I have data each 15 min.
What is the best way to do that? I am completly on Kapacitor. I am using
the version 0.13
Here the first part:
* 21 forecasteec*
* 22 |join(real)*
* 23 .as('forecasteec', 'real')*
* 24 |eval(lambda: abs( "forecasteec.value" - "real.value"))*
wug
