# 9 Applications

#### Overview

Applications are used to group items in logical groups.

For example, the *MySQL Server* application can hold all items related
to the MySQL server: availability of MySQL, disk space, processor load,
transactions per second, number of slow queries, etc.

Applications are also used for grouping web scenarios.

If you are using applications, then in *Monitoring → Latest data* you
will see items and web scenarios grouped under their respective
applications.

#### Configuration

To work with applications you must first create them and then link items
or web scenarios to them.

To create an application, do the following:

-   Go to *Configuration → Hosts* or *Templates*
-   Click on *Applications* next to the required host or template
-   Click on *Create application*
-   Enter the application name and click on *Add* to save it

You can also create a new application directly in the item properties
form.

Items are linked to applications in the item properties form. Select one
or more applications the item will belong to.

Web scenarios are linked to applications in the web scenario definition
form. Select the application the scenario will belong to.
