Hi all,  
after the upgrade to 6.0.0 of my elk stack, i receive in every node the following error:

[ERROR][o.e.x.m.c.n.NodeStatsCollector] [node1] collector [node\_stats] timed out when collecting data

and monitoring is not working.  
Can someone explain me how to solve?

What version did you upgrade from? What upgrade process did you follow?  
Can you show us the entire log entry?
