Application¶
A tool to create a semantic group of processes.
What is an Application¶
Application is a way to group certain processes, preferably belonging to an application that is running on the host. Think of application as a bucket that holds processes.
Need¶
To create a semantic grouping of processes that can be used to filter processes from a list.
For instance, after running discovery on a host, two processes are found. Out of those, one is a Java process and the other is an Nginx process. Say both these processes are part of an application called ISCRUM. Using application, you can create a bucket that holds these two processes. Using this bucket, you can always find all the processes belonging to the ISCRUM application and perform operations like X-ray on them.
Usage¶
Applications are defined at a project level and can be used in the Discover feature's process view or Transform feature's process view.
How to Create an Application¶
The application can be created in the Rationalize page. Let's look at how you can create an application.
Application Name Constraints¶
- You can create an application with a name having a length up to 15 characters
- Application name can have alphanumeric characters only; no special characters are allowed except hyphens (-) and periods (.)
