Simple query logging for debugging

[jprante]

Hi Elasticsearch team,
some users want simple query logging, so I added some debug statements. By adding a line "search: DEBUG" in logging.yml, the node requested should output some information about query execution and the JSON source.

where should we put that in the logging.yml file? and where does it log to?

@bigerock This issue is a pull request, so it is not yet (if ever) incorporated into Elasticsearch.

thanks @brusic. i just had realized that. doh! if i understood compiling java i suppose i could download the changed files and merge and compile them?

The pull request at this point a year old and based on the 1.0.0.Beta1-SNAPSHOT branch. There might be some merge conflicts. You could checkout Jorg's fork and try to merge the branch and see what happens!

Another option is to enable slow logs and basically set the threshold to 0ms: http://www.elasticsearch.org/guide/en/elasticsearch/reference/current/index-modules-slowlog.html

thanks - that enable slow logs is much easier. very much appreciated!!

Hi @jprante

Thanks for this PR. We've talked about it and, given that the slow log will log all queries if the threshold is zero, all of the clients provide client-side query logging, and the fact that we have a query profiler in the works #6699, we've decided not to include this change.
