• OS version: CentOS 7.3.1611 in an AWS EC2 instance.
• Docker version: docker-engine-17.05.0.ce-1.el7.centos.x86_64
• Collectd version: collectd-core-5.7.1_librato1.413-0.x86_64

Steps:

1. Install docker on the instance and run some containers.
2. Download the Ansible Librato role and patch with https://github.com/librato/ansible-librato/pull/4 because varnish-libs rpm was missing in the repo at provisioning time of writing.
3. Provision with these relevant settings:

   librato_rh_version: '5.7.1_librato1.413'
   librato_hostname: "{{ ec2_tag_Hostname }}"
   librato_fqdn_lookup: false
   librato_enabled_plugins: ['docker']
   librato_docker_host: "{{ inventory_hostname }}"
   librato_docker_port: 2375
   librato_logging_use_log_file: true
   librato_logging_log_file_log_level: err
   librato_logging_log_file_filename: stdout

I'm getting some metrics, but also getting these errors: (use sudo journalctl -u collectd -f to see the errors)

Note: I've checked and compared the collectd-docker.py in /opt/collectd/share/collectd/collectd-docker.py on the instance is the same as in this repo's collectd-docker.py file. Everything except the copyright is the same.
