# Amazon Cloudwatch Logs JavaScript SDK v2 code examples
|
||
|
|
## Purpose
|
||
|
|
The code examples in this directory demonstrate how to work with Amazon CloudWatch Logs
|
||
|
|
using the AWS SDK for JavaScript v2.
|
||
|
|
|
||
|
|
You can use Amazon CloudWatch Logs to monitor, store, and access your log files from Amazon Elastic Compute Cloud (Amazon EC2) instances, AWS CloudTrail, Route 53, and other sources.

||
|

|
||
|

### API examples

|
- [Delete a CloudWatch log subscription filters](./cwl_deletesubscriptionfilter.js)
|
||
|
|
- [Describe CloudWatch log subscription filters](./cwl_describesubscriptionfilters.js)
|
||
|
|
- [Put a CloudWatch log subscription filter](./cwl_putsubscriptionfilter.js)

|
## Important
|
||
|
|
|
||
|
|
- As an AWS best practice, grant this code least privilege, or only the
|
||
|
|
permissions required to perform a task. For more information, see
|
||
|
|
[Grant least privilege](https://docs.aws.amazon.com/IAM/latest/UserGuide/best-practices.html#grant-least-privilege)
|
||
|
|
in the *AWS Identity and Access Management User Guide*.
|
||
|
|
- This code has not been tested in all AWS Regions. Some AWS services are
|
||
|
|
available only in specific AWS Regions. For more information, see the
|
||
|
|
[AWS Regional Services List](https://aws.amazon.com/about-aws/global-infrastructure/regional-product-services/)
|
||
|
|
on the AWS website.
|
||
|
|
- Running this code might result in charges to your AWS account.

## Running the code
|
||
|
|
|
||
|
|
### Prerequisites
|
||
|
|
- An AWS account. To create an account, see [How do I create and activate a new AWS account](https://aws.amazon.com/premiumsupport/knowledge-center/create-and-activate-aws-account/) on the AWS Premium Support website.
|
||
|
|
- AWS credentials. For details, see [Setting credentials in Node.js](https://docs.aws.amazon.com/sdk-for-javascript/v2/developer-guide/setting-credentials-node.html) in the
|
||
|
|
*AWS SDK for Javascript (v2) Developer Guide*.
|
||
|
|
- The AWS SDK for JavaScript (v2). For AWS SDK for JavaScript download and installation instructions, see
|
||
|
|
[Installing the AWS SDK for JavaScript](https://docs.aws.amazon.com/sdk-for-javascript/v2/developer-guide/installing-jssdk.html) in the
|
||
|
|
*AWS SDK for JavaScript (v2) Developer Guide*.
|
||
|
|
|
||
|
|
Most of these code example files can be run with very little to no modification. For example, to use Node.js to run
|
||
|
|
the `cwl_deletesubscriptionfilter.rb` file, replace the hard-coded values in the file with your own values, save the file, and then run the file. For example:
|
||
|
|
|
||
|
|
```
|
||
|
|
node cwl_deletesubscriptionfilter.js
|
||
|
|
```
