Filter alarms

The Query Favorites of InTouch Alarm Viewer control define a set of alarm provider, alarm group, an optional node name, and a priority range under one name. The alarm provider, alarm group, and the node name are used for subscribing to a specific alarm group. The priority range on the other hand is used to filter the alarms from the given alarm group.

The Filter Favorites of InTouch Alarm DB View control define a set of any number of criteria you want to filter from the Alarm Database under one name.

In summary, Filter Favorites fulfill a purely filtering function whereas Query Favorites fulfill a subscription and a filtering function at the same time.

The Alarm Control filtering feature unites both these concepts by exclusively using filter conditions and subscribing to the necessary alarm providers on demand.

Filters can be saved and used in both run time and historical modes.

The filter conditions can be re-used between different client modes. For example, if you define node name, provider name, alarm group, and a priority range for the current alarms, you can also use this filter to retrieve the historized alarm data of the same source from the Alarm Database instead.

Filter definitions will be saved per user so operators working on the same server can access different saved filters.
