## Core Concepts

### Metrics

Time-ordered data points published to CloudWatch. Key components:
- **Namespace**: Container for metrics (e.g., `AWS/Lambda`)
- **Metric name**: Name of the measurement (e.g., `Invocations`)
- **Dimensions**: Name-value pairs for filtering (e.g., `FunctionName=MyFunc`)
- **Statistics**: Aggregations (Sum, Average, Min, Max, SampleCount, pN)

### Logs

Log data from AWS services and applications:
- **Log groups**: Collections of log streams
- **Log streams**: Sequences of log events from same source
- **Log events**: Individual log entries with timestamp and message

### Alarms

Automated actions based on metric thresholds:
- **States**: OK, ALARM, INSUFFICIENT_DATA
- **Actions**: SNS notifications, Lambda functions, Auto Scaling, EC2 actions, Systems Manager OpsItems
- **Types**: metric (incl. metric math, anomaly detection, Metrics Insights), composite, log (scheduled Logs Insights query evaluated M-out-of-N on query results)
- **Mute rules**: scheduled windows that mute actions while alarms keep evaluating

## Common Patterns

### Create a Metric Alarm
