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: 'your@email.com',
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);
