Application Monitoring

An application is a group of identical or similar components divided based on business requirements. Applications are classified into system applications and custom applications. System applications are discovered based on built-in discovery rules, and custom applications are discovered based on custom rules.

After application discovery rules are set, Application Operations Management (AOM) automatically discovers applications that meet the rules and monitors related metrics. For details, see Configuring Application Discovery.

Procedure

In the navigation pane, choose Monitoring > Application Monitoring.
Click an application. On the details page that is displayed, manage and monitor components in batches by application.
You can also view the component list, host list, and alarm analysis result of the current application.
On the application details page, click the View Monitor Graphs tab and monitor application metrics.
You can also perform the following operations:
- Adding an application
  For the same or similar components that are discovered by default discovery rules or that are not installed with APM probes, you can group them logically, that is, add them to the same application for monitoring.
  
  In the upper right corner of the Application Monitoring page, click Create Application to add a custom application discovery rule. For details, see Configuring Application Discovery. After the rule is added, you can monitor the application. AOM can display O&M information by component. For details, see Component Monitoring.
- Creating a view template
  AOM provides default view templates, such as Application Template. You can modify the default view templates, and can also click the plus sign (+) in to create custom templates.
- Adding a metric graph
  You can click to add a line graph or to add a digit graph to the view template. You can also delete, move, and copy metric graphs in the view template according to Dashboard.
- Adding a view template to a dashboard
  On the application details page, choose More > Add To Dashboard in the upper right corner to add the view template to the dashboard for monitoring.
