Re: Logging which client connected to Solr
We do something similar and include the server's hostname in solr's response.
To accomplish this you'll have to write a class that extends
org.apache.solr.servlet.SolrDispatchFilter and put your custom class in place
as the SolrRequestFilter in solr's web.xml.

Hello,
I’m investigating the possibility of logging the username of the client who
did the search on Solr along with the normal logging information. The
username is in the basic auth headers of the request, and the access control
is managed by an Apache instance proxying to Solr. Is there a way to append
that information to the Solr query log, so that the log would look like this:
INFO - 2014-03-27 11:16:24.000; org.apache.solr.core.SolrCore; [generic]
webapp=/solr path=/select params={lots of params} hits=0 status=0 QTime=49
username=juha
I need to log both username and the query, and if I do it directly in Apache
then I lose the information about amount of hits and the query time. If I log
it with Solr then I get query time and hits, but no username. Username
logging is higher priority requirement than the hits and query time, but I’m
looking for solution that covers both cases.
Has anyone implemented this kind of logging scheme, and how would I
accomplish this? I couldn’t find this as a configuration option.

Re: Logging which client connected to Solr
You could always just pass the username as part of the GET params for the
query. Solr will faithfully ignore and log any parameters it doesn¹t
recognize, so it¹d show up in your {lot of params}.
That means your log parser would need more intelligence, and your client
would have to pass in the data, but it would save any custom work on the
server side.

Re: Logging which client connected to Solr
I assume you are passing extra info to Solr.
Then you can write servletfilter to put it in NDC or MDC which can then be
picked up by log4j config pattern.
This approach is not Solr specific. Just usual servlet/log stuff.
