Environment Application Metrics and Logs

Monitor application metrics and logs for a deployed environment.

This guide covers CloudWatch charts, application log streams, and basic runtime diagnosis.

About Application Monitoring

The App page shows runtime metrics for your deployed application. Metrics come from Amazon CloudWatch and can include request duration, invocations, concurrent executions, throttles, and availability.

The Logs tab streams application log lines so you can inspect recent request and runtime output.

Monitoring Application Health

To review performance charts, inspect application metrics, and stream live logs for one environment, you can use the application monitoring panel.

Before you start

Your application must be deployed. Metrics are most useful after the application receives traffic.

Steps

1. Click Projects in the global sidebar.
2. Click your target project.
3. Click the target environment in the projects list.
4. Click App in the environment sidebar.
5. Click Metrics to review charts.
6. Click Logs to view the CloudWatch log stream.

What happens next

The page displays runtime charts and log output for the selected environment.

NOTE: When availability drops or duration rises, compare the metric timestamp with nearby log entries.
