The one thing that comes to mind is grabbing your cluster state and then running it through jq (or similar) to look for various settings. There's no direct way to do this that I know of. Someone else might have a better idea though! ---

Cluster state would not include the settings for each index of it. I am expecting some \_cat/indices API has option to get to know about index settings or other API call which would list the indices based on settings conditions are met. ---

I'm pretty sure that's exactly what would be in there (with other things). > [@tusharnemade](#): > > I am expecting some \_cat/indices API has option to get to know about index settings or other API call which would list the indices based on settings conditions are met. That does not exist. Your other option is to raise a feature request and hope that it is implemented. ---

My mistake, I should have checked details properly. `curl -XGET "10.10.10.2:9200/_cluster/state/blocks/indices?pretty"` I got indices details who are in READ-ONLY.. Need to use some formatting tool to get data properly. Will check on that too. Thank You @warkolm ---

Look at using `jq` or something similar. ---
