Hello, Is there any way to hook up to ES and listed for slow queries? By slow queries I mean [http://www.elasticsearch.org/guide/reference/index-modules/slowlog.html](http://www.elasticsearch.org/guide/reference/index-modules/slowlog.html) . I'd love to be able to have some sort of a listener and do something custom (e.g. log elsewhere, index, analyze, rewrite, etc.) with slow queries. If there is no way to do that, should I open an issue? ## Thanks, Otis ElasticSearch Performance Monitoring - [http://sematext.com/spm/index.html](http://sematext.com/spm/index.html) ---

Otis, Slow queries are logged by a standard ES logger. The logging.xml file configures this logger to use DailyRollingFileAppender to log slow query messages to a separate file. You can replace DailyRollingFileAppender with your own custom appender by adding your appender to the elasticsearch classpath and specifying your appender's class name in appender: index\_search\_slow\_log\_file: type: com.sematext.YourCustomAppender ...

As igore pointed out, an appender is the only way to go. We could allow for plugins to register custom listeners for it.
