Hi,  
I have elastic-HQ for the diagnosis of ES cluster.  
I do manual refresh/flush/clear\_cache from HQ.

Can I set up cron job to execute these API calls?

Does it helps to improve health anymore?

Any other automatic option to improve health parameters?

br,  
Sunil

I've never had to automatically refresh or flush. Both are automatically called on schedules. I have heard of folks automatically clearing caches but that was a thing mostly from the 1.x days. I haven't heard of it as thing in 5.x but I could be wrong.
