# CloudWatch code examples for the SDK for JavaScript (v3) ## Overview Shows how to use the AWS SDK for JavaScript (v3) to work with Amazon CloudWatch. _CloudWatch provides a reliable, scalable, and flexible monitoring solution that you can start using within minutes._ ## ⚠ Important - Running this code might result in charges to your AWS account. For more details, see [AWS Pricing](https://aws.amazon.com/pricing/?aws-products-pricing.sort-by=item.additionalFields.productNameLowercase&aws-products-pricing.sort-order=asc&awsf.Free%20Tier%20Type=*all&awsf.tech-category=*all) and [Free Tier](https://aws.amazon.com/free/?all-free-tier.sort-by=item.additionalFields.SortRank&all-free-tier.sort-order=asc&awsf.Free%20Tier%20Types=*all&awsf.Free%20Tier%20Categories=*all). - Running the tests might result in charges to your AWS account. - We recommend that you grant your code least privilege. At most, grant only the minimum permissions required to perform the task. For more information, see [Grant least privilege](https://docs.aws.amazon.com/IAM/latest/UserGuide/best-practices.html#grant-least-privilege). - This code is not tested in every AWS Region. For more information, see [AWS Regional Services](https://aws.amazon.com/about-aws/global-infrastructure/regional-product-services). ## Code examples ### Prerequisites For prerequisites, see the [README](../../README.md#Prerequisites) in the `javascriptv3` folder. ### Single actions Code excerpts that show you how to call individual service functions. - [Create a metric alarm](actions/put-metric-alarm.js#L6) (`PutMetricAlarm`) - [Delete alarms](actions/delete-alarms.js#L6) (`DeleteAlarms`) - [Describe alarms for a metric](actions/describe-alarms.js#L6) (`DescribeAlarmsForMetric`) - [Disable alarm actions](actions/disable-alarm-actions.js#L6) (`DisableAlarmActions`) - [Enable alarm actions](actions/enable-alarm-actions.js#L6) (`EnableAlarmActions`) - [List metrics](actions/list-metrics.js#L6) (`ListMetrics`) - [Put data into a metric](actions/put-metric-data.js#L6) (`PutMetricData`) ## Run the examples ### Instructions **Note**: All code examples are written in ECMAscript 6 (ES6). For guidelines on converting to CommonJS, see [JavaScript ES6/CommonJS syntax](https://docs.aws.amazon.com/sdk-for-javascript/v3/developer-guide/sdk-examples-javascript-syntax.html). **Run a single action** ```bash node ./actions/ ``` **Run a scenario** Most scenarios can be run with the following command: ```bash node ./scenarios/ ``` ### Tests ⚠ Running tests might result in charges to your AWS account. To find instructions for running these tests, see the [README](../../README.md#Tests) in the `javascriptv3` folder. ## Additional resources - [CloudWatch User Guide](https://docs.aws.amazon.com/AmazonCloudWatch/latest/monitoring/WhatIsCloudWatch.html) - [CloudWatch API Reference](https://docs.aws.amazon.com/AmazonCloudWatch/latest/APIReference/Welcome.html) - [SDK for JavaScript (v3) CloudWatch reference](https://docs.aws.amazon.com/AWSJavaScriptSDK/v3/latest/client/cloudwatch) --- Copyright Amazon.com, Inc. or its affiliates.
