Hello,

I didn’t find nginx module for “fair” Tomcat load balancing.  
My understanding, that by default nginx load balancing round robins  
through  
a list of upstream servers.  
Is any way for load balance to take into account also current cpu load  
of  
that app.server?

Thank you,

Ruslan

Not directly related to CPU load, AFAIK the closest to that is:
