Does anyone know if there is a list of ES logging libraries explained anywhere? I'm trying to enable DEBUG with the root logger

{ "transient": { "logger": { "\_root": "INFO" } } }

Which is great, except there are a lot of lines (especially from XPACK) that I do not care about and can't seem to find any documentation on the names and uses of different logging libraries. If anyone has any direction to point me that would be helpful.

I do notice that you get the shorthand name in the log line itself but not sure if there's a way for me to expand that to the full name:

o.e.x.s.a.e.ReservedRealm
