graylog2 you could create a stream that routes on the "source" field (which
is the hostname) and then be able to review your logs in aggregate or by

Subject: about Solr log file


I have two questions about Solr log file.

Is it possible to set log setting to use one log file for each core?
Because of I run many cores on one Solr and log file is getting bigger and
bigger and it makes me to hard to debug when system error.

Is there any setting to gather Solr Cloud logs at any one server?
I have plan to migrate to Solr Cloud but it seems that each sold node makes
log at their local disk.
