Lightbits on AWS Event Log
Lightbits on AWS records cluster events in a dedicated CloudWatch log group.
The cluster events are intended to give users a clear view of the cluster operations - including deployment, maintenance operations, and backups.
As part of the deployment process, a new AWS LogGroup named EventLogGroup is created under the user’s root stack.
The EventLogGroup contains separate log streams for deployment, maintenance, and backup processes - allowing users to easily monitor relevant processes.
