@kaecyra I'm running into an issue trying to parse Docker logs using FluentD logging driver.

Error is:

Logs are emitted with tag marathon.requestbin.

My FluentD conf:

<match marathon.requestbin*>
    type burrow
    key_name log
    action inplace
    remove_prefix marathon
    format json
</match>

<match requestbin*>
  type stdout
</match>

Here is what the log look like on stdout:

2015-11-25 21:38:11 +0000 marathon.requestbin: {"log":"10.42.122.245 - - [25/Nov/2015 21:38:11] \"GET /delay/2 HTTP/1.1\" 200 -","container_id":"467f6f962940172a8c5a21e2dce3354d23604ed73386975c37a533455989f822","container_name":"/mesos-a84767fb-caaf-46cb-921c-e083f441715a-S1.7e7380da-fb88-4429-b26a-8449ad6edd1b","source":"stderr"}

Any ideas? Thanks in advance for looking at it.

How are these logs being read? From a file?

scalp42 commented 8 years ago

From the default forward port localhost:24224 (https://docs.docker.com/engine/reference/logging/fluentd/ if it helps).
