Issues sending logs to an external log aggregator via FluentD

Issue

• I would like to send a copy of my openshift cluster logs to both the internal ES as well as a fluentd secure forwarder I am finding that when I set the configmap/logging-fluentd to use secure_forward it stops sending logs to my local ES in openshift. Is there a way to send logs to both openshift internal ES as well as send them out to a secure-forwarder?
  • We are using an external log aggregator to send our logs from Fluentd. After following the instruction on https://docs.openshift.com/container-platform/3.5/install_config/aggregate_logging.html, we still couldn't set it up correctly.
