+# CloudWatch
+
+NHS Screening wrapper around selected submodules from
+[terraform-aws-modules/cloudwatch/aws](https://registry.terraform.io/modules/terraform-aws-modules/cloudwatch/aws/latest)
+that provides a single module entry point for common CloudWatch log and alarm building blocks.
+
+## Included submodules
+
+- `log-group`
+- `log-stream`
+- `log-metric-filter`
+- `metric-alarm`
+- `metric-alarms-by-multiple-dimensions`
+
+## What this module enforces
+
+| Control | How it is enforced |
+| ------- | ------------------ |
+| Single entry point | One shared wrapper exposes the requested CloudWatch submodules together |
+| Creation gate | Each submodule is gated by `module.this.enabled` and a non-null config object |
+| Naming | Names are derived from `module.this.id` |
+| Tagging | Log groups and alarms that support tags receive `module.this.tags` |
+| Minimal interface | Only the minimal required or functionally necessary configuration is exposed |
+
+## Usage
+
+### Complete example
+
+```hcl
+module "cloudwatch" {
+  source = "git::https://github.com/NHSDigital/screening-terraform-modules-aws.git//infrastructure/modules/cloudwatch?ref=main"
+
+  service     = "bcss"
+  project     = "shared-resources"
+  environment = "prod"
+  stack       = "monitoring"
+  name        = "application"
+
+  log_group = {}
+
+  log_stream = {}
+
+  log_metric_filter = {
+    pattern                         = "ERROR"
+    metric_transformation_name      = "ErrorCount"
+    metric_transformation_namespace = "BCSS/Application"
+  }
+
+  metric_alarm = {
+    comparison_operator = "GreaterThanOrEqualToThreshold"
+    evaluation_periods  = 1
+    threshold           = 10
+  }
+
+  metric_alarms_by_multiple_dimensions = {
+    comparison_operator = "GreaterThanOrEqualToThreshold"
+    evaluation_periods  = 1
+    threshold           = 10
+    dimensions = {
+      lambda1 = {
+        FunctionName = "function-one"
+      }
+      lambda2 = {
+        FunctionName = "function-two"
+      }
+    }
+  }
+}
+```
+
+## Conventions
+
+- Set a submodule object to `null` to skip creating that submodule.
+- `log_stream` and `log_metric_filter` depend on `log_group` being configured in the same module call.
+- `metric_alarm` and `metric_alarms_by_multiple_dimensions` derive their metric name and namespace from `log_metric_filter`.
+- `metric_alarm` uses fixed defaults of `period = "60"` and `statistic = "Sum"`.
+- `metric_alarms_by_multiple_dimensions` uses fixed defaults of `period = "60"` and `statistic = "Sum"`.
+- CloudWatch log streams and log metric filters do not support tags directly, so only the submodules that accept tags receive `module.this.tags`.
