fluent-plugin-dockergelf

Fluentd filter plugin to handle gelf format log in docker(kubenetes)

The log looks like 

{"log":"{"_instance_id":"","_microservice_id":"","host":"","level":4,"short_message":"Some log information.","timestamp":1539143207.2754333,"version":"1.1"}","stream":"stderr","time":"2018-10-10T05:05:17.102912076Z"}

This filter will use the timestamp inside as the timestamp. create a new field called logtime as the timestamp from the docker. move the short_message to the log field.

The latest kubernetes_metadata filter does not support the inner json process anymore. So this filter is recommended to put between detect_exceptions and kubernetes_metadata. 

    <filter kubernetes.**>
      @type dockergelf
    </filter>
