This topic shows you how to obtain an overview of an application. On the Overview tab of the application, you can view the application topology, number of requests, response time, number of slow calls, and HTTP status codes.

Prerequisites

The Application Real-Time Monitoring Service (ARMS) agent is installed for an application. For more information, see Overview.

Procedure

  1. Log on to the ARMS console. In the left-side navigation pane, choose Application Monitoring > Applications.
  2. On the Applications page, select a region in the top navigation bar and click the name of the application that you want to manage.
