Amazon web services – Process Daily Logs from Cloudwatch using lambda

I dont have much code to show.

I want to process all cloudwatch logs that are generated in last 1 day using lambda.
I want to execute lambda 6 am in the morning to extract some information from cloudwatch logs that are generated on previous day and put it in a table.

    Instead of your 6 AM idea, you could also use a CloudWatch Logs subscription filter and trigger a Lambda function to process and store the log entries as described in a step-by-step example here Example 2: Subscription filters with AWS Lambda.

    Or even easier and without duplicating the data to a database: Analyzing log data with CloudWatch Logs Insights

    I assume that you have a lot of Lambda functions and each has a CloudWatch Log Group.

    You can try the CloudWatch Log Group subscription filter, with this feature you can stream your logs into any support destinations such as Lambda.

    Before that, you should prepare a Lambda function that has functionalities to help you to put your extracted data into DynamoDB table.
