Hi, I have a problem with nxlog. Try to start service nxlog with kafka configuration (including installation librdkafka) and unfortunately i have an error with starting nxlog:
error: "Unit nxlog.service has begun starting up.
Jan 03 17:24:12 Kafka4 nxlog[19220]: 2018-01-03 17:24:12 ERROR Failed to load module from /opt/nxsec/libexec/nxlog/modules/output/om_kafka.so, /opt/nxsec/libexec/nxlog/modules/output/om_kafka.so: undefined symbol: rd_kafka_last_error;DSO load failed Jan 03 17:24:12 Kafka4 systemd[1]: nxlog.service: control process exited, code=exited status=1 Jan 03 17:24:12 Kafka4 systemd[1]: Failed to start NXLog daemon. -- Subject: Unit nxlog.service has failed -- Defined-By: systemd"
Please use the librdkafka package from the EPEL repo: https://centos.pkgs.org/7/epel-x86_64/
