mackerel-plugin-aws-billing is mackerel agent plugin that gets AWS cost and makes a graph.

It uses AWS CloudWatch Api to get AWS Billing Data related to AWS Account.
It can make a graph on Service Metric.
It gets AWS cost every hour by using AWS API because unlike other metrics, AWS updates cost once in a few hours.
It writes cache file on server every hour, and uses cache to output data.

(※In order to output data to Service Metric, this plugin sends data to mackerel instead of mackerel-agent because mackerel-agent can not send data to Service Metric.)

Caution: You must must enable Billing Alerts.(see https://docs.aws.amazon.com/ja_jp/awsaccountbilling/latest/aboutv2/monitor-charges.html)
