A software engineer needs to enhance an application's observability by tracking the frequency of new user registrations each minute. The application resides on a widely-used cloud platform. Which technique would enable the engineer to most effectively monitor this activity and facilitate immediate analysis?
Increment a counter attribute within a managed NoSQL database service for each registration
Capture user registration events in a bucket service for objects for later retrieval and manual inspection
Use the monitoring service's API for custom metric data submission for direct ingestion and analysis
Invoke a serverless computing service to periodically tally the signup events
