Hi,

Maybe this is more Docker related question, but maybe someone can suggest something.

I use Windows Server 2016  
Hosting ES version 7.1.1 in Docker container microsoft/windowsservercore- ltsc2016

I've built an image with the health check command  
...  
HEALTHCHECK --interval=5s `CMD powershell -command`  
try { `$content = (iwr -useb http://localhost:9205/_cat/health).Content;`  
$health = $content.Split(' ')[3]; `if ($health -eq 'green' -or $health -eq 'yellow') { return 0 }`  
else { return 1 }; `  
} catch { return 1 }  
..

Now every 5 seconds, Powershell script executes and takes 50% CPU.  
If I run 2 containers with ES and one with Kibana, CPU usage is 100%

Could you suggest another health check approach in this case?
