Describe the issue:

ISM policies get applied intermittently , sometime works and other time it doesn’t . No errors or warning in opensearch logs.

How to enable debug/tracing for ISM only to get more insight into why the policy is not applied all the time. ?

I applied debug setting , I don’t get enough information or errors on logs as to why ISM policies are implemented at times .
