This is possible by semi-automatic detection of anomalies over time for some preset of fields used for grouping the events (aka dimensions) and another preset of fields used in stats calculations (aka metrics). In general case this is hard to resolve taks, since it is impossible to check for anomalies across all the possible combinations of dimensions and metrics for wide events with hundreds of fields.

This is also complicated by the possibility to apply various filters for the events before and after ststs' calculations.
