Using Elastic 8.10.4 version.

1. How to enable slow logs for existing indices and future indices? Also how to skip the system level indices?

2. If i need to disable slow logs after testing, how to disable it?

Hi @Test_Test3,

Welcome to the community! In terms of your questions:

1. You can configure the thresholds [at an index level as covered in the documentation](https://www.elastic.co/guide/en/elasticsearch/reference/current/index-modules-slowlog.html#index-slow-log). I'm not sure about system-level indices, but it's possible to do that by setting `index.indexing.slowlog.source` to `false` or `0`.
2. If you're wanting to test things out you could try playing with the levels as [listed here](https://www.elastic.co/guide/en/elasticsearch/reference/current/index-modules-slowlog.html#_slow_log_levels) .

Hope that helps!

I have lot of indices existing and cannot apply to individually. so applying \* will make it applicable to system indices like .kibana, ilm indices etc., which i dont want so any regex pattern to skip the special indices starts with a dot(like .kibana)

If i enable using below  
"index.search.slowlog.threshold.query.info": "0s",

how to disable the above? should i set the value again to -1 ?
