Hi Ryan,

* If the loggerName attribute is missing, it defaults to the fully-qualified class name of
LoggingInfoStream (see default value used for getting the attribute).

* I will update the example solrconfig.xml, good call!

* Even if the logs are being sent to the same file, the logger name is almost always part
of the formatter configuration. For the solrconfig.xml perhaps a good example would be
{noformat}
<infoStream loggerName="org.apache.solr.update.LoggingInfoStream.${solr.core.name}">
{noformat}

(I _think_ that actually will substitute core name correctly, will check...).

> {{LoggingInfoStream}} that was introduced in SOLR-4977 does not log any core context.
> Previously this was possible by encoding this into the infoStream's file path.
> This means in a multi-core setup it is very hard to distinguish between the infoStream
messages for different cores.
> {{LoggingInfoStream}} should be automatically configured to prepend the core name to
log messages.
