Group Log For Free

Your Lambda function comes with a CloudWatch Logs log group and a log stream for each instance of your function. The Lambda runtime environment sends details about each invocation to the log stream, and relays logs and other output from your function's code.

Follow these guidelines when naming a log group: Log group names must be unique within a Region for an AWS account. Log group names can be between 1 and 512 characters long. Log group names consist of the following characters: a-z, A-Z, 0-9, '_' (underscore), '-' (hyphen), '/' (forward slash), '.

Lambda automatically streams details about each function invocation, along with logs and other output from your function's code to CloudWatch Logs. Log groups are a standard part of CloudWatch and used to organize all logging. Any log generated by a Lambda function uses the naming convention /aws/lambda/function-name .

Log in to your CloudWatch console ( ). Select Logs from left navigation pane. Click Actions > Create Log Group. Type the name of your log group. For example, CloudTrailAuditLogs .

Log groups Each log stream has to belong to one log group. For example, if you have a separate log stream for the Apache access logs from each host, you could group those log streams into a single log group called MyWebsite.com/Apache/access_log .

Log in to your CloudWatch console ( ). Select Logs from left navigation pane. Click Actions > Create Log Group. Type the name of your log group.

A log file provides a detailed and easily accessible record of system information that would otherwise be difficult to collate. It provides insight into the performance and compliance of your applications and systems. Log files are crucial for cloud applications because of their dynamic and distributed features.

Log group names can be between 1 and 512 characters long. Log group names consist of the following characters: a-z, A-Z, 0-9, '_' (underscore), '-' (hyphen), '/' (forward slash), '. ' (period), and '#' (number sign)

Lambda automatically integrates with CloudWatch Logs and pushes all logs from your code to a CloudWatch Logs group associated with a Lambda function, which is named /aws/lambda/ <function name> .
