The \_ilm/policy/my\_policy api can get which indices use this policy in current version, but in 7.10, the response does not contains in\_use\_by info.  
How to get the similar info(in\_use\_by) in ES 7.10?  
I noticed Kibana can show the policy's linked indices count, how does Kibana support that?

It seems kibana(7.10) use /\*/\_ilm/explain to collect all indices ilm explain info and calculate linked indices' count.  
BTW ES(7.17) use lifecycle.name in index settings in cluster state to calculate usage.

I would recommend you upgrade to at least 7.17 as the version you are using is quite old and has been EOL a long time.
