StackNag is a simple Slack integration that:
- Sends notifications about running OpsWorks stacks, the hourly costs of their associated resources, and "total usage" cost that includes resources from non-running stacks (ebs volumes, rds instances, s3 buckets, etc).
- Generates AWS cost metrics and posts these metrics to CloudWatch. Currently it publishes metrics for hourly cost breakdowns by service, as well as a total hourly cost, number of running stacks and total stacks.
