Hello,

Anyone knows if we can combine forecasts data with watchers. For example, I have created a forecast job that predicts the behavior of a product after 3 weeks. So, now I want gather these data and create a threshold alert using watchers.  
How can I use the data and how can I create an alert?

Thank you very much in advance!  
Angelos

The results from a forecast run will be in the `.ml-anomalies-*` index with `result_type:model_forecast` and `job_id:<jobname>`

The fields `forecast_prediction`, `forecast_upper` and `forcast_lower` are what you're looking for!

corresponds to:

In your watch, you'd query this index, potentially with a timeframe of `now+3d` or whatever the amount of time you'd like to look into the future that you have forecast results for.

(I'm assuming you know Watcher basics about querying an index for a particular time range)
