# fluent-plugin-ec2-metadata

Fluentd plugin to add ec2 metadata fields to a event record

## Installation
Use RubyGems:

    gem install fluent-plugin-ec2-metadata

## Configuration

Example:

    <match foo.**>
      type ec2_metadata

      aws_key_id  YOUR_AWS_KEY_ID
      aws_sec_key YOUR_AWS_SECRET/KEY

      output_tag ${instance_id}.${tag}
      <record>
        hostname      ${tagset_name}
        instance_id   ${instance_id}
        instance_type ${instance_type}
        az            ${availability_zone}
        vpc_id        ${vpc_id}
      </record>
    </match>

Assume following input is coming:

```js
foo.bar {"message":"hello ec2!"}
```

then output becomes as below (indented):

```js
i-28b5ee77.foo.bar {
  "hostname"      : "web0001",
  "instance_id"   : "i-28b5ee77",
  "instance_type" : "m1.large",
  "az"            : "us-west-1b",
  "vpc_id"        : "vpc-25dab194",
  "message"       : "hello ec2!"
}
```

### Placeholders

The following placeholders are always available:

* ${tag} input tag
* ${tag_parts} input tag splitted by '.'. you can use it like `${tag_parts[0]}` or `${tag_parts[-1]}`
* ${instance_id} instance id
* ${instance_type} instance type
* ${availability_zone} availability zone
* ${region} region

The followings are available when you define `aws_key_id` and `aws_sec_key`:

* ${vpc_id} vpc id
* ${subnet_id} subnet id
* ${tagset_xxx} EC2 tag (e.g. tagset_name is replaced by the value of Key = Name)
