[Why] I use a fluentd to collect docker logs, and use three output plugins:stdout/es/mq. But when I use them at the same time, will meet some problems. This fluentd will be very slow. Logs will be stacked. Another problem is that dockerd always sends logs to the same worker of fluentd.The multi-process function of fluentd can't work. [How] Change the architecture. A fluentd collects docker logs, do stdout and forward logs to master-fluentd. master-fluentd send logs to es and mq. Like this: |-----------| |--------|--> stdout |--------------|---> es |docker logs| --> |fluentd | |master-fluentd| |-----------| |--------|--> forword---> |--------------|---> mq
