# Application Instances

Application instances card displays the number of running app instances (Healthy and unhealthy). Each application can have one or more instances (replicas) running. The application instances data is real time. To view details, click Expand.

## App Instances Details Page

The App instances details page provides a graphical view to navigate quickly to the number of user app running instances over time in the selected time range. You can view the unhealthy incidents captured during the life cycle of the running app instances. The time graph gives an observability of the number of running app instances that have unhealthy incidents recorded in the selected time range. By selecting the time range using the slider, you can narrow down to the exact participating apps in the bottom app list. This enables you to do further analysis on the causes of the unhealthy incidents.

You can view the following information on the App instances details page. The data displayed in the table is updated based on the time range that you select in the graph.
