Data

Data is used to show and create variables used by Shinken to perform checks.

Those values are also called Macros.

As shown on the picture, when creating a new host, no data are available, even if the new host inherit from Template.

Data are displayed in two sections :

• Local : data for this host only (custom data)

Data from templates are seperated by template names.

This allow Administrators to see what and where data have been get.

Data are represented by a Key and a Value.

When data are local, both of them can be modified.

When data are inherited, only values can be modified.
