Subject Re: Solr 7.2 solr.log is missing
Date Mon, 02 Apr 2018 18:14:18 GMT
Technically, Solr doesn't name the file at all, that's in your log4j
config, this line:

log4j.appender.file.File=${solr.log}/solr.log

so it's weird that you can't find it on your machine at all. How do
you _start_ Solr? In particular, to you define a system variable
"-Dsolr.log=some_path"?

And also note that there are three log4j configs, and it's easy to be
using one you don't think you are using, see SOLR-12008.

Best,
Erick
