A Policy is a container of Rule Sets that may be applied to a Folder. Rule Sets contain copies of all the different types of Alarms that NiTO offers, which can be configured independently per Rule Set.
To edit Policies and Rule Sets, and their associations with devices and alarms:
- Click the Finder icon on the main sidebar on the far left of the screen
- Select a folder
- Choose the Policy tab.
Policy-Folder Association
A folder may be associated with a single Policy, either by inheritance or directly.
- When a folder does not have a Policy of its own, it inherits Rule Sets (which contain alarms) from the closest ascendant folder.
- Any changes you make within a Policy affects all devices in the associated folder and sub-folder under that Policy.
- If you clone a Policy into a sub-folder, you completely detach inheritance for that sub-folder from any ascendant policy.
- Any changes you make within a cloned Policy after it has been created will affect only devices within the directly associated sub-folder and its children.
- Rule Set and Alarm configurations from the closest ascendant Policy/folder of a sub-folder that has its own Policy, do not apply to that sub-folder and its children.
Default and Explicit Rule Sets
- All Policies have at least one Rule Set, called the ‘Default Rule Set’. A Policy’s Default Rule Set can be renamed, but not removed.
- Additional Rule Sets can be added to and removed from a Policy, referred to as ‘Explicit Rule Sets’.
- Devices may be manually assigned to one or more Explicit Rule Sets.
- Devices not assigned to an Explicit Rule Set are automatically assigned to the Default Rule Set.
- Devices assigned to an Explicit Rule Set are automatically unassigned from the Default Rule Set.
Rule Set Alarms / ‘Shared Alarms’
Rule Sets contain a wide variety of Alarms that apply to all the devices that are associated with that Rule Set. The Default Rule Set exists to help ensure that no devices are without alarms. Explicit Rule Sets allow you to fine tune the alerting condition for specific device(s), or to define multiple alarms with different conditions for the same device(s). When you modify the thresholds of any alarms directly attached to a Rule Set, you modify those thresholds for all devices within the Rule Set, except where device-specific alarms are defined.
