6.1.1 Non-virtual objects

There are three non-virtual object types in the system obeying the following three rules:

·     Sites: Each site has a name and an optional descriptive text. Each site can contain arbitrary many sites and equipment. Each site is below another site, and this relation can be modified during the existence of the site. The initial site is an exception to this rule which can only contain sites and cannot be modified or deleted. The name of the site has to be unique only inside the site containing it, although it is recommended to keep it globally unique.

·     Equipment: Each piece of equipment belongs to a site. This relation can be modified during the existence of the equipment. The name of the equipment has to be unique in the whole system globally.

·     Measurements: The equipments contain the measurements which cannot be moved to another piece of equipment.

The measurement server group assignment is also propagated in the site equipment hierarchy: if there is no server group given for the equipment, then during the assignment of the equipment to a measurement server the system is stepping up in the site hierarchy till it finds a place where the server is already defined. Meanwhile, both for the equipment and for the site only those measurement server groups are considered whose type coincides with the type of the equipment, i.e. even if an SNMP group is assigned to the site containing a piece of equipment, the equipment will not be assigned to it if its type is Oracle.

Each piece of equipment can be assigned to at most two measurement servers: a primary and a secondary one. The secondary measurement server measures the given equipment only temporally. On the configuration page the individual equipments and sites are color coded similarly to the current measurements page, but here not on the basis of the existing threshold violations, but according to whether the equipment has no running measurement server, or one of its measurement servers is not running or the status of one of its servers is unknown.
