public class AlarmFactory
extends BaseFactory

Creates CloudWatch alarms for application health monitoring.

This factory sets up alarms to notify you when your infrastructure isn't behaving as expected. Alarms are automatically tuned based on your security profile - stricter thresholds in production, more relaxed in development.

Alarms Created

• ALB 5xx Errors - Backend server errors indicating infrastructure problems
• ALB 4xx Errors - Client errors that might indicate misconfiguration
• High Response Time - Performance degradation alerts

Usage

 new AlarmFactory(this, "Alarms", new AlarmFactory.Props());
 

The factory automatically connects to your load balancer through the context system. All alarms adapt to your environment - production gets strict monitoring, development stays lenient to avoid alert fatigue.

Threshold Examples

Alarm Thresholds by Security Profile

Alarm	Dev	Staging	Production
5xx Errors	10/min	7/min	5/min
4xx Errors	50/5min	30/5min	20/5min
Response Time	5s	3s	2s

• for security-focused monitoring (CPU, memory, logins)
• for custom alarm thresholds

Constructor Details

AlarmFactory

public AlarmFactory(software.constructs.Construct scope,
 String id,
 AlarmFactory.Props p)

Creates a new alarm factory.

Parameters:

scope - the CDK construct scope

id - the construct ID

p - configuration properties (reserved for future use)

Method Details

create

public void create()

Creates CloudWatch alarms for the application load balancer.

Sets up multiple alarms covering error rates and response times. All thresholds adapt automatically to your security profile for appropriate sensitivity in each environment.

Lifecycle: Alarms are automatically deleted when the CloudFormation stack is destroyed. No manual cleanup required.
