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.

# Example automatically generated from non-compiling source. May contain errors.
import { Watchful } from 'cdk-watchful'

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:

# Example automatically generated from non-compiling source. May contain errors.
import { Watchful } from 'cdk-watchful'
import * as sns from '@aws-cdk/aws-sns';
import * as sqs from '@aws-cdk/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: '[e-mail]',
  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.

# Example automatically generated from non-compiling source. May contain errors.
wf.watchScope(storageLayer);

Example
