Host/service templates check_command inheritance #503

Open mohierf opened 6 years ago

mohierf commented 6 years ago

If an inherited host/service template do not define a check_command the created host/service do not have any check command and it gets the default host/service check command.

The expected behavior is to have the check_command defined in one of the base templates!

For instance, inheriting from two templates should provide the check_command of the tempalte which has one defined check_command

Indeed, the templates list order is of many importance for this ! The host will inherit the last template check_command even if it is set to None! Then it will be replaced with the default host check_command defined in the backend ...

When needing to inherit from multiple templates:

if some templates inherit each other, the most specialized one will take precedence for the check command
if some templates are not self inheritant, define the one to get check_command from as the last one in the _templates list used when host is created
