| Doc Text: |
Cause: The environment variable JOURNAL_READ_FROM_HEAD is set to the empty string. This causes the default value of read_from_head for the journald input to be true. When Fluentd starts up for the first time on a node, it reads in the entire journal.
Consequence: It may take hours for system messages to show up in Elasticsearch and Kibana.
Fix: Fluentd will check if the value is set _and_ is not empty, otherwise, it will use a default of false.
Result: Fluentd will read from the tail of the journal when it starts up on a new node.
