Fluent::Plugin::Cloudfront::Log

This plugin will connect to the S3 bucket that you store your cloudfront logs in. Once the plugin processes them and ships them to FluentD, it moves them to another location(either another bucket or sub directory).

Example config

<source>
@type       cloudfront_log
log_bucket  cloudfront-logs
log_prefix  production
region      us-east-1
interval    300
aws_key_id  xxxxxx
aws_sec_key xxxxxx
tag         reverb.cloudfront
verbose     true
</source>

Configuration options

log_bucket

This option tells the plugin where to look for the cloudfront logs

log_prefix

For example if your logs are stored in a folder called "production" under the "cloudfront-logs" bucket, your logs would be stored in cloudfront like "cloudfront-logs/production/log.gz". In this case, you'd want to use the prefix "production".

moved_log_bucket

Here you can specify where you'd like the log files to be moved after processing. If left blank this defaults to a folder called _moved under the bucket configured for @log_bucket.

moved_log_prefix

This specifices what the log files will be named once they're processed. This defaults to _moved.

region

The region where your cloudfront logs are stored.

interval

This is the rate in seconds at which we check the bucket for updated logs. This defaults to 300.

aws_sec_id

The ID of your AWS keypair. Note: Since this plugin uses aws-sdk under the hood you can leave these two aws fields blank if you have an IAM role applied to your FluentD instance.

aws_sec_key

The secret key portion of your AWS keypair

tag

This is a FluentD builtin.

thread_num

The number of threads to create to concurrently process the S3 objects. Defaults to 4.

s3_get_max

Control the size of the S3 fetched list on each iteration. Default to 200.

delimiter

You shouldn't have to specify delimiter at all but this option is provided and passed to the S3 client in the event that you have a weird delimiter in your log file names. Defaults to nil.

verbose

Turn this on if you'd like to see verbose information about the plugin and how it's processing your files.

Installation

Add this line to your application's Gemfile:

gem 'fluent-plugin-cloudfront-log'

And then execute:

$ bundle

Or install it yourself as:

$ gem install fluent-plugin-cloudfront-log

Development

After checking out the repo, run bin/setup to install dependencies. You can also run bin/console for an interactive prompt that will allow you to experiment.

To install this gem onto your local machine, run bundle exec rake install. To release a new version, update the version number in version.rb, and then run bundle exec rake release, which will create a git tag for the version, push git commits and tags, and push the .gem file to rubygems.org.
