Logs
- In your app → Logs you see live everything your app writes with console.log, plus errors (stderr, in pink).
- Pause freezes the view so you can read; Filter searches for text; Download saves what you see as a .log file.
- The build log (install and compile) is in Deployments → View log.
Metrics
- In Metrics pick 1 h, 6 h, 24 h or 7 days to see CPU (100% = 1 vCPU) and memory usage, with the dashed limit line.
- Resources belong to the plan and are shared by all its apps: if one uses a lot, the others get less.
If memory hits the limit, the system restarts the app. If it happens often, look for memory leaks or add the +512 MB RAM add-on from My services.
