Rancher-logging-fluentd too much log in stdout


my /var/log partition is almost filled with stdout logs from rancher-logging-fluentd. Is there a way to limit that ? Moreover, logs from stdout seem unreadable
2020-01-30 11:32:39 +0000 [warn]: #0 pattern not matched: "2020-01-30T11:32:28.97425706Z stdout F \\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\

Perhaps it’s because it harvests its own logs ? (https://github.com/fluent/fluentd-kubernetes-daemonset/issues/364 something like that). Is so how can we exclude them ?

For now, I add -qq to the command line to avoid these warnings but that’s not a long term solution… Maybe I should fill a bug ?
