Filtering of elastic search data


i have configured elastic search for storing windows event logs. I am able to dispaly it in grafana using JSON data with selected fields. Now I woulf like to use filtering.

I have table containing event_id and event_data.TargetUserName. event_data.TargetUserName can contain user account, blanks, and computer accounts. computer account is in format servername$

I need to filterout all blanks, and words ends with $.

I tryed to make some query like: NOT event_data.TargetUserName: /^.*[^]/ but it didnt worked. How to write correct filter? That regex i tested with rubular and there it worked,



You’re using:

  • table panel?
  • ad-hoc filters?

Can you include some screenshot that shows how you apply your filter?
