I am using

HTTP as input and elastic search as output.

I am getting logs from 100 different HTTP sources.  
For each source, i am creating different conf file input and output.

when I am running each conf file CPU utilisation become 100%.  
Also after running some time I am getting java heap size error.

I increased my java heap size as 4029m.

Still, I am facing the same issue.

can someone please help me in architecture how better I can handle 100 HTTP input request.

My logstash version is 5.0.2

Thanks in Advance.........
