Hover Templates

Introduction

Hover templates are html files with some macros in it. These files can be used as hover menus for the objects on the maps. The hover templates are located in share/userfiles/templates relative to the nagvis root directory. The templates are named like this: *.hover.html. There are macros which are available in hover menus of all object types and some which are only available for some special objects. All standard macros are listed below.

The section macros define that the included code will be removed if the hover template is not parsed for this type. For example a section macro for host macros looks like this: <!-- BEGIN host -->.+?<!-- END host -->
