This program is primarily intended to assist with billing. Collects various AWS statistics, exports them as prometheus metrics, and saves them in RDBMS.
Run help or check main.go for program parameters Debug messages are enabled by default
Currently the following metrics are exported:
- aws_ec2_instances_count: Count of istances
- instancesNormalizationUnits: Normalization units of istances
The following labels are exposed:
- aws_tag_: Any tags passed in with the -instance-tags flag are added as labels
- az: Availability zone
- family: Instance family

- instance_id: Id of instance
- instance_type: Type of instance
- launch_time: Time on which instance was started
- lifecycle: spot, scheduled or normal instance

- requester_id: The ID of the entity that launched the instance on your behalf (default to owner id if none is present)
- state: State of instance (pending | running | shutting-down | rebooting | terminated | stopping | stopped)
- units: The normalization units of the instance
Every set of instance reservations gets its own time series, this is intended to allow the end time of reserved intances to be tracked and potentially alerted upon.

- status_message: The reason for the current status of the Reserved Instance listing. The response can be blank
- status: The status of the listed Reserved Instances (active, cancelled, closed, pending)
- units: The normalization units of the Reserved Instances
Only fullfilled active spot instances requests are currently tracke
- aws_ec2_spot_request_actual_block_price_hourly_dollars: The price paid for limited duration spot instances
- aws_ec2_spot_request_bid_price_hourly_dollars: Your maximum bid price
- aws_ec2_spot_request_count: How active spot instances of a given type you have running
The following labels are exposed:

Your aws credentials should either be in $HOME/.aws/credentials , or set via AWS_ACCESS_KEY and AWS_SECRET_ACCESS_KEY
Usage of /go/bin/aws_audit_exporter: -addr string port to listen on (default ":9190") -duration duration How often to query the API (default 4m0s) -instance-tags string comma seperated list of tag keys to use as metric labels -region string the region to query (default "us-east-1")

}Writes data to postgres to allow longer retention, and data aggregations Was tested on postgresql 9.6 in RDS
Some information in the DB is eventual consistent, i.e. it will take a full iteration for data to be updated.
hstore extention needs to enable on the database in use Run with a privelleged user:
aws_audit=> CREATE EXTENSION hstore;
