You can then use this information to\n[read model output streams](/vision-ai/docs/read-stream)\nand [get assets](/vision-ai/docs/manage-assets-api#get-asset). \n\n### Web UI\n\nView an app's instances and output in the Google Cloud console.\n\n1. Open the **Applications** tab of the Vertex AI Vision dashboard.\n\n [Go to the Applications tab](https://console.cloud.google.com/ai/vision-ai/applications)\n2. Select the name of the app you want to view. This takes you to the\n application details page.\n\n The application details page displays a table with application resources.\n This table lists all the running instances of the application. Each input\n stream to the application has its own instance. Each instance has\n its own input and output resources listed under it.\n\n3. To inspect the stream or warehouse asset resources in the instance table,\n click on the input or output ID, or select the path.\n\n - If you click on **stream** resource, you are redirected to the\n stream details page, where you can inspect the detailed information of\n that stream.\n\n To learn how to read a model's output stream using the command line,\n see [Create and manage Streams](/vision-ai/docs/read-stream).\n\n - Clicking on the **warehouse asset** resource takes you to the\n Vision Warehouse asset details page.\n\n To get a Vision Warehouse asset, see [Manage resources\n using the Vision Warehouse API](/vision-ai/docs/manage-assets-api#get-asset).\n\n### REST\n\nTo list app instances, send a GET request by using the\n[projects.locations.applications.instances.list](/vision-ai/docs/reference/rest/v1/projects.locations.applications.instances/list)\nmethod.\n\n\nBefore using any of the request data,\nmake the following replacements:\n\n- \u003cvar translate=\"no\"\u003ePROJECT\u003c/var\u003e: Your Google Cloud [project ID or\n project number](/resource-manager/docs/creating-managing-projects#identifying_projects).\n- \u003cvar translate=\"no\"\u003eLOCATION_ID\u003c/var\u003e: The [region](/about/locations) where you are using Vertex AI Vision.

If your app has more than 20 instances you must create and\nremove instances incrementally with the API. The recommended workflow is as\nfollows:\n\n1. Create your app.\n2. Add 1-20 experimental instances.\n3. Deploy your application.\n4. Verify your app works as expected.\n5. Use the [`createApplicationInstances`](/vision-ai/docs/reference/rest/v1/projects.locations.applications/createApplicationInstances) method to incrementally add more inputs to the deployed application.\n6. Allow app to run.\n7. Use the [`deleteApplicationInstances`](/vision-ai/docs/reference/rest/v1/projects.locations.applications/deleteApplicationInstances) method to incrementally remove inputs from deployed applications.\n8. Undeploy the application.\n\n| **Caution:** For a single application there can only be *one* update request running at a time. You are responsible for queueing these types of requests, and performing the necessary retries if there is a failure."]]
