# AppSail in the Console

## The Overview Section

The *Overview* tab contains the general details of the app service, the [deployment URL](https://docs.catalyst.zoho.com/en/serverless/help/appsail/key-concepts/appsail-execution/#custom-domain-url), and a live dashboard of the instances that are actively running.

![appsail-app](https://catalyst-docs-development.zohostratus.in/images/help/appsail/appsail-docker-image-deployed.png)

These include the details of the [admin or collaborator](https://docs.catalyst.zoho.com/en/getting-started/set-up-a-catalyst-project/collaborators/) that deployed the app, the date and time of the app's creation and last deployment, and a **unique AppSail ID** created for your app automatically after you deploy it. 

This will also specify if the app is a Catalyst-managed runtime or a custom runtime, and if the source is the CLI, console, or a container registry service. You can find the Image Path or URL of the image from its container registry service, in the last case.

### AppSail URL

After your AppSail service is deployed, Catalyst hosts your app on a sub-domain with which you can access it. You can access the various endpoints that you configure in your app from this base URL.

The default base URL of your AppSail service will be of this format for development environment:

```json
https://appsailservicename-ZAID.development.catalystappsail.com
```

For example:

```json
https://demoservice-1011034735.development.catalystappsail.com
```

This will be the format for the production environment:

```json
https://appsailservicename-ZAID.catalystappsail.com
```

* **AppSail service name:**  The name you provide while initializing or deploying the app

* **ZAID:** The unique identifier that maps an application to a project

> **Note:** The "development" indicates the development environment of your project. After you [deploy your project to production](https://docs.catalyst.zoho.com/en/deployment-and-billing/environments/introduction/), the URL will not include that key.

#### Custom AppSail URL

Catalyst provides you with the convenience of editing the AppSail service name and ZAID part of the URL, and adding any sub-domain name of your choice for the AppSail URL. The "catalystappsail" domain will remain the same in this method, along with the "development" key for the apps in the development environment. 

1. You can edit the AppSail URL by clicking the **Edit AppSail URL** from the Overview section.

2. Enter the sub-domain name that you require, then click **Update**.

### Live dashboard 

The dashboard displays every currently running instance of the app after it is invoked. 

![appsail-dash-1](https://catalyst-docs-development.zohostratus.in/images/help/appsail/appsail-live-instance-1.png)

AppSail spawns a new instance for your app after a running instance is almost entirely consumed. You will be able to see the percentage of consumption of each instance, and details such as the unique **Instance ID** and the duration it has been running for.

You can click **Refresh** to get an updated status of the active instances, in case there are lags.

### Delete an Active Instance

You can manually delete an active instance if you require, in cases when you experience a bug or a deadlock situation, such as an infinite loop bug. 

1. Click the ellipsis icon for an instance, then click **Delete**.

2. Click **Yes, Proceed** in the confirmation pop-up.
