I'm struggling to add http remote ip address in solr (jetty) log file.I've tried to modify the server/resources/log4j.properties file, which seems to control the output log format, but I'm unable to understand how to add in ConversionPattern the proper ip address field. log4j.appender.file.layout.ConversionPattern=%d{yyyy-MM-dd HH:mm:ss.SSS} %-5p (%t) [%X{collection} %X{shard} %X{replica} %X{core}] %c{1.} %m%n
I don't think this can be done in solr.log without changes to the Solr code. As far as I know, there is no option you can give to log4j to log the IP address. Solr doesn't keep track of the IP address, so it definitely isn't available to the logging framework.
Solr would need to *get* the remote address from the servlet container, probably in SolrDispatchFilter, and pass that information down the stack to SolrCore, where requests are actually logged. The API is not designed to pass IP addresses, so a mechanism would probably have to be created.
I would actually like to see this feature, so opening an enhancement issue in Jira is advisable.
The request log in Jetty can give you this information. In server/etc/jetty.xml, there is a config section already there for a request log, but it is commented so it's not active.
Thanks, Shawn
