From your logs, it looks like this might have been a temporary condition during the first startup of the node. I don't have the first log of 6.2.3 handy to check.

Did the NPE stop after 2018-03-26T16:27:41 ? If not, I could start up 6.2.3 to see if I can reproduce your issue.

If you're using Kibana does Monitoring work in Kibana?

Regards,
Lee
