I am getting unknown fields in .monitoring-es-\* Index. I recently enabled stack monitoring in ELK Stack then I am getting data in .monitoring-\* Indices. I wanted to create alerts based on this data but I am unable to use term in one field. I digged more then found field is unknown hence I am not able to use in search queries. Please help me to resolve this issue ?
