The TrueSight console enables you to see the status of all your applications. You can view all the applications that are created manually and that are automatically discovered in your network, and you can sort by application importance or severity. You can select a single application and drill down to investigate the source of an application issue.
To view the status summary of all applications, click Monitoring > Applications in the TrueSight console. In parentheses next to the Applications page title is the number of monitored applications.
The color of an application indicates the current severity of events on an application. The application severity is calculated as follows:
Each event has a severity level associated with it. The severity level in combination with the importance indicates the seriousness of the event and the urgency of the need to take action. For example, a high severity level for an event with low importance is no cause for alarm, but a high severity level for an event with high importance indicates an urgent need for action. Even if the severity of one device or monitor instance in an application is critical (denoted by the color red), the severity of the entire application becomes red. The following figure is a snapshot of the Applications page based on severity.
In the following figure, one application is red with a corresponding icon
, indicating that the severity is critical. All the other applications are green with a corresponding icon , indicating that no events or transaction problems are detected and the severity is OK.You can click the name of any application to view details of that application. You can analyze problems of that application and view the application model. For more information, see Viewing the details of an application.
Example of the Applications page
You can sort and filter applications by the severity of application events or by the designated importance of the applications.
The appearance of an application reflects the highest severity of one or more events on the application.
The severity is indicated by different colors and icons:
Severity | Icon | Description |
---|---|---|
Critical (red) | At least one monitored metric exceeded the defined Critical threshold. | |
Major (dark orange)* | At least one monitored metric exceeds the defined Major threshold. | |
Minor (light orange) | At least one monitored metric exceeded the defined Minor threshold . | |
Warning (yellow-orange)* | At least one monitored metric exceeded the defined Warning threshold. | |
Information (blue) | Information about the application | |
OK (green) | No monitored metrics exceed the defined thresholds. |
*For applications that are automatically generated, the Major and Warning severity levels do not apply.
Application importance is sorted by high, medium, and low. For applications created in the TrueSight console, you can set the importance when you create an application. For applications discovered by App Visibility, the importance is set as medium by default. You can change the importance for either kind of application, later.
If the App Visibility agent captures transaction data during a port scan, such as that used by antivirus software, the Applications page might display an application name that appears to be random characters.
You can resolve this issue in one of the following ways:
