I'd like to get a greater detail on discovery process when a node starts. I found this: ES 7.3 Logging configuration
So, I think this is the best approach:
./bin/elasticsearch -E <name of logging hierarchy>=<level>
My problem: I can't find documentation about the valid hierarchies and levels. Where can I find it? What's the right hierarchy and level for my purpose?
log4j2.properties file I found some posible hierarchies, but I'd like to be sure.
Thanks in advance.
