This topic tells you how to view and manage apps and service instances with Apps Manager.

Overview

You can use Apps Manager to manage apps, service instances, service keys, and route services. This includes tasks such as scaling apps, binding apps to services, generating services keys, and more.

For information about managing orgs and spaces, see Managing Orgs and Spaces Using Apps Manager.

You can manage apps and service instances across multiple foundations. For more information, see [Configuring Multi-Foundation Support in Apps Manager](https://docs.vmware.com/en/VMware-Tanzu-Application-Service/4.0/tas-for-vms/configure-multi-foundation.html).

Prerequisite

To view and manage apps and service instances with Apps Manager, you must log in to Apps Manager with an account that has adequate permissions.

For more information, see About Permissions in Getting Started with Apps Manager.

Manage an App

This section describes how to manage an app in Apps Manager.

You can do the following tasks to manage apps in Apps Manager:

  • View app summary information
  • Start and stop apps
  • Scale apps
  • View sidecar processes
  • View key app metrics
  • Bind apps to services
  • Manage environment variables and routes
  • View logs and usage information
  • View app revisions
  • Re-deploy app revisions
  • Delete apps
  • Terminate specific instances of apps

View App Overview

The Overview page for an app includes app summary information, such as app processes and instances, app memory and disk space, and app events.

There are two ways to locate an app Overview page:

  • On the space page, click the app you want to manage.
  • Search for an app by entering its name in the search bar.

The following image shows an example of an app Overview page.

alt-text=""

Start, Stop, or Restage an App

You can start, stop, and restage from the Overview page of the app. The start, stop, and restage buttons are located on the app Overview page next to the name of the app.

The following image shows the location of the start, stop, and restage buttons.

alt-text=The app name is shown to the left as a header 2 called app-0001-0000. To the right of the app name are three buttons: Stop, Restart, and Restage.

For more information about starting, stopping, and restaging apps with the Cloud Foundry Command Line Interface (cf CLI), see Starting, Restarting, and Restaging Apps.

Scale an App

From the app Overview page, you can scale an app manually or configure App Autoscaler to scale it automatically.

Scale an App Manually

To manually scale an app:

  1. Go to the app Overview page.

  2. Under Processes and Instances, click Scale to open the Scale app dialog.

    alt-text=In the Processes and Instances section of the Overview pane, the Scale button is located to the right of each process.

  3. Edit the number of Instances, the Memory Limit, and the Disk Limit as desired.

  4. Click Apply Changes.

Enable App Autoscaler

You can enable App Autoscaler to automatically scale your apps. For information about how to configure App Autoscaler to scale an app automatically, see Configure Autoscaling for an App in Scaling an App Using App Autoscaler.

If Metric Store is installed, you can view the following key metrics for an app in the Key Metrics section of the app Overview page:

  • CPU
  • Memory
  • Disk
  • Request Latency
  • Request Rate
  • Request Errors

For more information about each metric, see Interpreting metrics in Monitoring and troubleshooting apps with Metrics.

For each metric, the app Overview page includes a graph that shows metric behavior over the past three hours. You can hover over the data points on the graph to view the value of the metric. The page also includes the average value for the metric over the past three hours.

Metric Store is required for Apps Manager to display the Key Metrics section. For information about installing and configuring Metric Store, see Metric Store.

The following image is an example of an app Overview page, showing key metrics for the app.

alt-text=The example Apps Manager app overview page shows the six key metrics (CPU, Disk, Request Latency, Request Rate, and Request Errors).
