CloudWatch already holds the lines from your Lambda, ECS task, or unified agent. The first useful win on Logit.io is not a migration spreadsheet. It is one Log Group, the documented Lambda shipper posting to this stack's API, and rows in OpenSearch Dashboards Discover that show logGroupName, logStreamName, and message. If you are still proving that a Logs stack can accept anything at all, start with First Logs on Logit.io; this post assumes CloudWatch is the source and the Stack API is the pipe. Contents.
