merged upstream https://github.com/openshift/origin-aggregated-logging/commit/c68eea3d43aa6a9f808974883a7c039150349a82
The fix is implemented in rubygem-fluent-plugin-viaq_data_model-0.0.18-1.el7 - please verify that the fluentd image has this version (or later).
There isn't rubygem-fluent-plugin-viaq_data_model-0.0.18-1.el7 in v3.9.74.
gem list |grep fluent
Moving to MODIFIED - the bz is fixed - now it is up to ART/RCM to ensure that there is an image built with the right rubygem-fluent-plugin-viaq_data_model-0.0.18-1.el7 rpm . . .
The new JSON log messages handle are merged into version v3.9.78
