# Logs and status

Source: /docs/concepts/logs-and-status

The app page shows whether your app is running, what it is printing, and the history of its deploys.

## Runtime logs [#runtime-logs]

Expand **Runtime logs** to see what the running container is printing right now. **Refresh** re-reads them; **Copy** copies the visible output.

If the app is not running you see **App isn't running — deploy it to see its logs.** Deploy it first.

## Build logs [#build-logs]

During a deploy, the **Build log** streams the build output. When it ends it reads **Build succeeded** or **Build failed**. Past runs are under **History** and **Pipeline runs**.

## Status [#status]

The app's delivery status is one of **Not deployed**, **Up to date**, **Changes pending**, or **Deploy failed**. The lifecycle label (**pending**, **live**, **stopped**, and so on) is explained in [apps, builds and deploys](/docs/concepts/apps-builds-deploys).

## History [#history]

**History** has two tabs: **Deployments** and **Builds**, each filterable by status. **Pipeline runs** lists every deploy that ran, when, what triggered it (manual or push), and whether it succeeded.

## Restart versus redeploy [#restart-versus-redeploy]

* **Restart** (under **Actions**) runs the same image again. Use it to clear a stuck process. It does not rebuild.
* **Deploy** builds your current source into a new image and ships it. Use it after changing code.

## What can go wrong [#what-can-go-wrong]

* **"Couldn't load logs. Try refreshing."** — A transient read error. Refresh.
* **"App is not currently running"** (on Stop) / **"App is not currently stopped"** (on Restart) — The action does not apply in the app's current state.
* **"This app was stopped by an admin and can't be restarted. Contact support."** — An administrator suspended it. Reach [support](/docs/support).
* **"This action isn't available right now — the app may be mid-deploy."** — Wait for the running operation to finish, then retry.
