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?

this index is the biggest

It there any autocleaner?

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

None

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

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

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"
