You can delete the index directly but do note that this will remove all scalars from your experiments.

To delete you can use the following:

curl -XDELETE "localhost:9200/events-training_stats_scalar-d1bd92a3b039400cbafc60a7a5b1e52b"

It there any autocleaner?

None

Here is an example for auto cleaning. Did you delete ALL experiments?

I tried to delete all experiments but size of index didn't changed

this index is the biggest

Hi @<1579280543999070208:profile|SourFly7> , this index holds scalars of some experiments. You can reduce it by deleting some experiments. Do you have any other large scalar indices?

I have already tried this script but the index size is same
