Subject Re: Where did the milliseconds go?

I know the log settings can be changed. I’m asking about how the default was decided, and
whether it can be “improved”.

Oh, and I am referring to simply running the Solr example right out of the box, with its embedded
Jetty. No servlet container configuration involved.

In any case, the Solr tutorial should point people to super-easy-to-follow instructions for
how to get a “reasonable” log format. Do such instructions exist? I could only find the

Neither of which fits my definition of super-easy-to-follow, which is why I think getting
the default “right” is super important.

Are both of those wikis considered up to date? I did see a reference to Solr 3.5.

It depends on how you configure the log format in your servlet container. Solr no longer enforces
one, just add the correct logging jar.


Please don’t start the flamewar again. It’s easy and more universal, now. What you see
is just the default logging.

I personally have found it useful to see time in the Solr log include milliseconds, but it
is no longer included, even in 3.6.1.


Actually, I do see it in the first few log entries, but then the log format changes:

INFO: JNDI not configured for solr (NoInitialContextEx)


I much prefer the initial header format:


2012-08-17 10:41:35.826:INFO:oejsh.ContextHandler:started


To the revised header format:


Aug 17, 2012 10:41:35 AM org.apache.solr.core.SolrResourceLoader locateSolrHome



Oh, and it looks like every log entry in the new format occupies TWO lines.


Was this a conscious and Solr community-consensus decision, or just an inadvertent side effect
of updating log jars?


Can we get the old format back?
