Hi @Marc Vázquez! Could you check which command does Confluent stack runs for zk? [root@node2 ~]# ps -ef | grep -i zookeeper 1001 3802 1 0 Jun12 ? 00:00:56 /usr/jdk64/jdk1.8.0_112/bin/java -Dzookeeper.log.dir=/var/log/zookeeper -Dzookeeper.log.file=zookeeper-zookeeper-server-node2.log -Dzookeeper.root.logger=INFO,ROLLINGFILE -cp #Thousands of libs... -Xmx1024m -Dcom.sun.management.jmxremote -Dcom.sun.management.jmxremote.local.only=false org.apache.zookeeper.server.quorum.QuorumPeerMain /usr/hdf/current/zookeeper-server/conf/zoo.cfg ps: did you set this cluster using the confluent.sh? If so, i made a research at their code and it should exists an directory for zk logs 😞 https://github.com/confluentinc/confluent-cli/blob/master/src/oss/confluent.sh#L414 Or if you prefer, you can try to set it manually, here's my example of log4j.properties for ZK.
