Logging elastic4s client

Question

looking at this example

client.execute{search in "places"->"cities" query "paris" start 5 limit 10}

is there an option to hook logging to client.execute to log all operations made by the client (index, search etc') ?

I saw this answer but I do not want to do something like :

val req = search in "index" / "type" query "kate bush"
logger.debug(s"Search request ${req.show}")

I want the client to log all base on the logging level

If you enable the DEBUG level in your logging configuration then you'll see some more output about whats' going on internally. — Val, Jan 24 '17 at 12:32
@Val thanks, it is enabled but I do not see any elastic4s output — igx, Jan 24 '17 at 13:04
@Val in my build sbt file ```logLevel in run := Level.Debug``` — igx, Jan 24 '17 at 13:36
@Val also tried adding this ```import org.elasticsearch.common.logging.ESLoggerFactory ESLoggerFactory.getRootLogger.setLevel("debug")``` But didn't really help — igx, Jan 24 '17 at 13:53
Elastic4s doesn't do much logging, but version 5.2.0 does a bit more. — sksamuel, Feb 02 '17 at 00:59

You can define your own ElasticClient, with overriding execute functionality

object MyElasticClientFactory {
     def fromClient(client: Client): ElasticClient = new ElasticClient {
     def close(): Unit = client.close()
     def java: Client = client

     override def execute[T, R, Q](request: T)(implicit executable: Executable[T, R, Q]): Future[Q] = {
         // TODO your logging here
         super.execute(request)
     }

}

Take a look at TcpClient for reference https://github.com/sksamuel/elastic4s/blob/9a4074b6ff5616b648801352b4c3629cd0fc9020/elastic4s-tcp/src/main/scala/com/sksamuel/elastic4s/TcpClient.scala
