3. cloudwatchlog_filer.js - Application which can retive log based on filters from AWS CloudWatchLogs

Requirements

The only requirement of this application is the Node Package Manager. All other dependencies (including the AWS SDK for Node.js) can be installed with:

npm install

Basic Configuration

You need to set up your AWS security credentials before the sample code is able to connect to AWS. You can do this by creating a file named "credentials" at ~/.aws/ (C:\Users\USER_NAME.aws\ for Windows users) and saving the following lines in the file:

[default]
aws_access_key_id = <your access key id>
aws_secret_access_key = <your secret key>

Config - For CloudWatchLog Application

You need to set up your AWS security credentials before the cloudwatchlog code is able to connect to AWS. You can do this by creating a file named "config.json" and saving the following lines in the file:

{ 
"accessKeyId": "you_access_key>, 
"secretAccessKey": <your_secret_access_key>, 
"region": <required_region> 
}

See the Security Credentials page. It's also possible to configure your credentials via a configuration file or directly in source. See the AWS SDK for Node.js Developer Guide for more information.

Running the application sample

This sample application connects to Amazon's Simple Storage Service (S3), creates a bucket, and uploads a file to that bucket. The script will automatically create the file to upload. All you need to do is run it:

node sample.js

This cloudwatchlog application connects to Amazon's CloudWatchLog,and retive the Log Groups, Log Streams, and Log Events for Filters from there. All you need to do is run it:
