✨ Have you heard of cdk-monitoring-constructs? ✨

Watchful on steroids. Check it out! 🔝

cdk-watchful

Watching your CDK back since 2019

Watchful is an AWS CDK construct library that makes it easy to monitor CDK apps. It automatically synthesizes alarms and dashboards for supported AWS resources.

declare const myTable: dynamodb.Table;
declare const myFunction: lambda.Function;
declare const myRestApi: apigw.RestApi;

const wf = new Watchful(this, 'watchful');
wf.watchDynamoTable('My Cute Little Table', myTable);
wf.watchLambdaFunction('My Function', myFunction);
wf.watchApiGateway('My REST API', myRestApi);

And...

Initialize

To get started, just define a Watchful construct in your CDK app. You can initialize using an email address, SQS ARN or both:

import * as sns from 'aws-cdk-lib/aws-sns';
import * as sqs from 'aws-cdk-lib/aws-sqs';

const alarmSqs = sqs.Queue.fromQueueArn(this, 'AlarmQueue', 'arn:aws:sqs:us-east-1:444455556666:alarm-queue')
const alarmSns = sns.Topic.fromTopicArn(this, 'AlarmTopic', 'arn:aws:sns:us-east-2:444455556666:MyTopic');

const wf = new Watchful(this, 'watchful', {
  alarmEmail: '[email protected]',
  alarmSqs,
  alarmSns,
  alarmActionArns: [ 'arn:aws:sqs:us-east-1:444455556666:alarm-queue' ]
});

Add Resources

Watchful manages a central dashboard and configures default alarming for:

  • Amazon DynamoDB: watchful.watchDynamoTable
  • AWS Lambda: watchful.watchLambdaFunction
  • Amazon API Gateway: watchful.watchApiGateway
  • Request yours

Watching Scopes

Watchful can also watch complete CDK construct scopes. It will automatically discover all watchable resources within that scope (recursively), add them to your dashboard and configure alarms for them.

declare const storageLayer: Stack;
declare const wf: Watchful;

wf.watchScope(storageLayer);
