AWS SQS (Prometheus)

  # SQS
  # https://docs.aws.amazon.com/AWSSimpleQueueService/latest/SQSDeveloperGuide/sqs-available-cloudwatch-metrics.html
  #
  # CloudWatch metrics for your Amazon SQS queues are automatically collected and pushed to CloudWatch at one-minute intervals.
  # These metrics are gathered on all queues that meet the CloudWatch guidelines for being active. CloudWatch considers a queue
  # to be active for up to six hours if it contains any messages or if any action accesses it. When an Amazon SQS queue is inactive
  # for more than six hours, the Amazon SQS service is considered asleep and stops delivering metrics to the CloudWatch service.

  # Configuration adapted from: https://sysdig.com/blog/monitor-amazon-sqs-prometheus/
