write custom event to aws cloudwatch logs

elizabeth_newman

I have a node.js application that I would like to monitor with AWS CloudWatch. I would like to be able to see not only the standard information that is logged (e.g. request and response times, etc.), but also custom information that I define (e.g. the name of the currently executing function).

Is there a way to write a custom event string to CloudWatch logs? If so, how would I do it?

There are a few ways to write a custom event string to AWS CloudWatch Logs. One way is to use the CloudWatch Logs Agent. The CloudWatch Logs Agent can be used to send both system logs and application logs to CloudWatch. To send custom application logs, you will need to first set up a new log group and then create a new log stream. Once you have done this, you can use the CloudWatch Logs Agent to send your custom logs to CloudWatch.

Another way to write a custom event string to AWS CloudWatch Logs is to use the CloudWatch Logs API. With the CloudWatch Logs API, you can programmatically send your custom logs to CloudWatch. To do this, you will need to first create a new log group and then create a new log stream. Once you have done this, you can use the CloudWatch Logs API to send your custom logs to CloudWatch.

Amazon CloudWatch Logs lets you monitor, store, and access your log files from Amazon Elastic Compute Cloud (Amazon EC2) instances, Amazon CloudTrail, Route 53, and other sources. You can then retrieve the associated log data from CloudWatch Logs using the Amazon CloudWatch console, the CloudWatch Logs commands in the AWS CLI, the CloudWatch Logs API, or the CloudWatch Logs SDK.

CloudWatch Logs uses an agent on your instance to monitor log files and send their data to CloudWatch. You can also configure CloudWatch Logs to collect log data from other AWS services such as Amazon Route 53, Amazon S3, and Amazon EC2. For more information, see What Is Amazon CloudWatch Logs?

To write a custom event string to Amazon CloudWatch Logs, you can use the CloudWatch Logs agent to push log data to CloudWatch. For more information about the CloudWatch Logs agent, see Installing and Configuring the CloudWatch Logs Agent.
