# TL;DR

We are using the filebeat `system` module to monitor our Docker logs. It worked correctly until our Docker team moved the log location from `/var/log/messages`. Now it no longer picks up the logs, even though we've added the new path to the `system` module. I've tested this on two different hosts, with the same results.

# The Long Story...

We are using the filebeat `system` module to ingest our Docker logs into Elasticsearch  
via Logstash. Initially, we our logs were writing to `/var/log/messages` and all was  
right with the world, our Docker logs were making it into ES as expected.

Our Docker team decided to move the logging target for Docker from `/var/log/messages` to `/var/log/docker/docker.log`. I added the following to the `/etc/filebeat/modules.d/system.yml`:

```
var.paths: ["/var/log/docker/docker.log"]

```

However, log events are no longer being ingested into ES, as expected. When I  
run filebeat in debug mode, I can see the following in the log, but no corresponding  
event is appearing in logstash.

```auto

    "hostname": "host001",
    "id": "75a8e64e-1e81-4896-8708-da8977ebc2eb"
  }
}

```

When I run Logstash in debug mode, I'm not seeing any errors that would appear to correspond to this.

I've also attempted to monitor the log directly, rather than through the `system` module, by adding the following to my `filebeat.yml`:

```auto
filebeat:
  inputs:
    - type: log
      paths:
        - '/var/log/docker/*.log'

```

However, this also does not appear to load events (I've been deleting `/var/lib/filebeat/registry` at each restart in order to force a full reload).

# Update

Just thought of adding this: Filebeat is running as root, and the log file has the following permissions and ownership:

```
-rw-r--r-- 1 root root 13425894 Aug 28 09:05 docker.log
```
