Make a working directory for holding your copies of various configmaps used by Fluentd. You will use this directory for subsequent steps below. The steps below assume the current directory is this directory:

  mkdir working_dir
  cd working_dir

Make sure you are in the logging project. This will be openshift-logging:

  oc project openshift-logging

Make a copy of the current logging-fluentd configmap:

  oc extract configmap/logging-fluentd --to=.

Make a copy of the original fluent.conf:

  if [ ! -f fluent.conf.orig ] ; then
        cp fluent.conf fluent.conf.orig
  fi

Edit fluent.conf - look for this:

    <label @OUTPUT>
    ## matches
      @include configs.d/openshift/output-pre-*.conf

Add a line between the line containing `## matches` and `@include configs.d/openshift/output-pre-*.conf` like this:

      @include configs.d/user/convert-to-single-index.conf

Add a new file to the current directory called convert-to-single-index.conf like this:

<filter **>
  @type record_transformer
  <record>
    viaq_index_name myindexname
  </record>
</filter>

Where `myindexname` is whatever indexname the customer wants to use.

Delete the configmap (that you saved above):

   oc delete cm logging-fluentd

Create the new one from the files in the current directory:

   oc create configmap logging-fluentd --from-file=.

Then restart fluentd (e.g. oc delete pod logging-fluentd-zzzz)
