Documentation

aws-cloudwatch

A self-contained CloudWatch observability bundle: a log group (retention + optional CMK encryption), a metric alarm, and a dashboard. Works with Terraform and OpenTofu (>= 1.6), AWS provider >= 6.0, < 7.0.

Out of the box the alarm and the dashboard target the log group itself (AWS/Logs / IncomingLogEvents), so the module stands up with nothing but a name and costs nothing to run. Point alarm_namespace / alarm_metric_name / alarm_dimensions at any real metric (EC2 CPUUtilization, ALB 5XX, a custom namespace, ...) when you wire it to a workload.

Secure / cost-aware defaults:

  • Log group is encrypted at rest (AWS-owned key by default; set kms_key_id for a customer-managed key — the key policy must allow logs.<region>.amazonaws.com)
  • Retention defaults to 7 days (never use 0 / never-expire unless you accept unbounded log storage cost)
  • Alarm treat_missing_data = "notBreaching" avoids false alarms when no data is flowing
  • Dashboards are free for the first three per account

Security notes

  • For regulated workloads set kms_key_id to a customer-managed KMS key so logs are encrypted with a key you control and audit; ensure its key policy grants logs.<region>.amazonaws.com the usual kms:Encrypt*/Decrypt/GenerateDataKey* permissions scoped by kms:EncryptionContext:aws:logs:arn.
  • Keep retention_in_days finite — 0 (never expire) accumulates cost and expands the data-retention surface indefinitely.
  • Send alarm_actions to an SNS topic with confirmed subscribers so alarms are actually actionable.

Requirements

  • Terraform or OpenTofu >= 1.6
  • hashicorp/aws >= 6.0, < 7.0
