# Read application logs

> Inspect running services and follow their output.

## Prerequisites

Run locally after authenticating. Find your application first:

```bash theme={null}
rig app ls --workspace WORKSPACE
rig app health --app APP
```

## Read and follow logs

```bash theme={null}
rig app logs --app APP
rig app logs --app APP --follow
```

Use Ctrl+C to stop following; this does not stop the app. Check for exceptions, missing configuration, and whether the process binds the configured port. Runtime output can include application secrets, so review it before sharing.

## Distinguish the failing stage

If the executable never started, read [install/build/release logs](/operate/build-logs). If the process runs but deployment fails readiness, compare the manifest with [health requirements](/configure/health). If health succeeds but a browser cannot open the URL, check [visibility](/guides/visibility) and [routing](/guides/expose-and-route).

For custom log sources and API streaming, follow the [App Logs API](/api-reference/app-logs/get-logs).
