Lumigo Insights is a system designed to automatically detect irregularities in serverless functions and trigger alerts when anomalies are detected. It solves the problem of not knowing about issues with applications or services until they become severe, allowing users to take action quickly. The system monitors functions for deviations from normal behavior, comparing data across different timeframes to identify spikes in invocations or error rates. Out-of-the-box alerts can be sent to Slack or email, and alerts can be muted, assigned to specific team members, or added to Jira tasks.
