How to use ISM to delete indexes by index pattern and age?

[McJava1967]

Hi all. I’m trying to use OpenSearch 2.12 ISM to delete indexes by index pattern and age. I’ve tried following the documentation (https://opensearch.org/docs/2.12/im-plugin/ism/index/), but no luck. Could anybody tell me what I’m doing wrong? This is my setup:

The older_than_one_day State is:

Destination state
delete
Transition trigger logic
Minimum index age is 1d

And the Delete state has only a Delete Action.

I would expect to see any indexes beginning with test-, heartbeat- or dev-* deleted after one day. But nothing happens. For instance, I still see indexes like test-lex-nam-sea-knams-2024.06.13, after this has been running for several days.

Could anybody help? HELP!

Did you see the index test-lex-nam-sea-knams-2024.06.13 in the page of Policy managed indexes? What’s the status of the policy execution on that index?

Ah! I don’t see that one. But I DO now see it IS working. It must have been my initial confusion setting this up that missed the 06-13 index. But I can see other, more recent, indexes are now getting deleted.

Thank you for your help!
