Cant' import Machine Learning Anomaly Jobs - I have Enterprise Cloud Subscription

The error message indicates that there is no data in your cluster that these ML jobs require in order to install and run. Refer to the job definitions which show the required data necessary: https://www.elastic.co/guide/en/siem/guide/current/prebuilt-ml-jobs.html

For example, you can see that the linux_anomalous_network_url_activity_ecs requires data collected by from Auditbeat (Linux). And, as you can imagine, the ML jobs whose names begin with windows requires data collected via winlogbeat.

Unless you've collected that kind of data using those beats, the product is working as expected by not allowing you to enable jobs on data that doesn't yet exist.
