Configure log4j level in Build Logs (particularly apache.http.wire)

Hello,

As part of a build step, the artefacts I have built in TeamCity are streamed to our deployment tool using the notoriously verbose classes in apache.http.wire.*.

These classes are producing a huge amount of DEBUG logging and the resultant TeamCity build logs are becoming too unwieldy to view.

Is there some way to configure the log4j settings for these build logs, which will filter down to these third party classes?

I've tried adding the following lines to /data/teamcity/application/conf/teamcity-server-log4j.xml:

<filter class="org.apache.http.wire">
  <param name="LevelMin" value="WARN"/>
</filter>

but so far nothing has made an impact.

Am I looking in the right place for this configuration?

Many thanks
