Use visitor pattern to create an alarm for every lambda with cdk-monitoring-constructs

lambdaMonitoringVistor.ts

import { IAspect } from "aws-cdk-lib";
import { NodejsFunction } from "aws-cdk-lib/aws-lambda-nodejs";
import { MonitoringFacade } from "cdk-monitoring-constructs";
import { IConstruct } from "constructs";


export class LambdaAlarms implements IAspect {
  monitoringFacade: MonitoringFacade;

  constructor(monitoringFacade: MonitoringFacade) {
    this.monitoringFacade = monitoringFacade
  }

  visit(node: IConstruct): void {
    if (node instanceof NodejsFunction) {
      this.monitoringFacade.monitorLambdaFunction({
        lambdaFunction: node,
        addFaultCountAlarm: {
          Critical: {
            maxErrorCount: 0
          }
        }
      })
    }
  }
}
