A. Write an AWS Lambda function that will query the logs every minute and contain the logic of which team to notify on which patterns and issues.
B. Set up different metric filters for each team based on patterns and alerts. Each alarm will notify the appropriate notification list.
C. Redesign the aggregation of logs so that each team’s relevant parts are sent to a separate log group, then subscribe each team to its respective log group.
D. Create an AWS Auto Scaling group of Amazon EC2 instances that will scale based on the amount of ingested log entries. This group will pull log streams, look for patterns, and send notifications to relevant teams.
