Hi, Apologies because I’m sure this is more of a scala n00b question than a Gatling-specific question. If so, if anyone could even just give me a few keywords to google for, I’m happy to RTFM. I just can’t (so far) seem to find the FM. When I run my sims I get a ton of useful logging output, and then a ton of not-as-useful stuff like `DEBUG c.n.h.c.p.n.NettyAsyncHttpProvider`. I notice that log4j is a transitive dep of the project; is this as simple as adding a log4j.properties to my classpath and configuring that stuff out of it? Or is there a more scala-y way to approach this? Thanks! Chris ---

In the conf/ folder, there is a logback.xml file. Does yours look like this one ? [https://github.com/excilys/gatling/blob/master/gatling-bundle/src/main/assembly/assembly-structure/conf/logback.xml](https://github.com/excilys/gatling/blob/master/gatling-bundle/src/main/assembly/assembly-structure/conf/logback.xml) If not, could you try commenting the loggers at the DEBUG level ? cheers Nicolas ---

Ah. I’m using gatling as a dependency (so, calling into the jar from my own code). I presume I can just put an override version of logback.xml somewhere? Just need to find out where. Thanks, I’ll poke around and see if I can find that. ---

Got it working by adding a logback.xml to my classpath, with the contents that you pointed me at. Much better. Thank you, Nicolas! ---

Glad to here that. ---

Hi, I am trying to achieve lesser verbose logging as well as last time I ran my performance test for 8hrs, jenkins ran into memory issues and job had to be killed. I can no longer access “[https://github.com/excilys/gatling/blob/master/gatling-bundle/src/main/assembly/assembly-structure/conf/logback.xml](https://www.google.com/url?q=https%3A%2F%2Fgithub.com%2Fexcilys%2Fgatling%2Fblob%2Fmaster%2Fgatling-bundle%2Fsrc%2Fmain%2Fassembly%2Fassembly-structure%2Fconf%2Flogback.xml&sa=D&sntz=1&usg=AFQjCNE5C3Va8EQIiUUt_PrHJUCStYaDrg)” file, Can you please post the contents of this file directly here for reference? I tried by completly commenting out the contents of logback.xml file but that did not help and I still see details being added to simulation.log. I am looking for a logging config just enough to view the final statistics while hiding the details of every single request made during test runs. Any suggestions? Thanks ---

Hi, How could logging (that usually goes on the console or a file) possibly be related to a memory issue? Your problem is probably related to the reports generation. You then have to increase the heap size. Note that we’ve released Gatling 1.5.4, that ships a fix for properly overriding JVM args on the gatling-maven-plugin.
