Opensearch Alerting

OpenSearch
1

I have started exploring Opensearch alerting, and got two issues/questions which I cant handle.

  1. when creating monitors we allowed to add only 1 Data filter? lets say I wanna have and/or relationship and filter based on multiple fileds, it is not possible?

  2. on Group by filter, I see only @version field and nothing else, what can be reason of it?

ragarding above issue, looks like using json editor helps to add keyword fields for group by but UI does not show them as option. We are on 2.3.0 , upgrade can help?
