The Alarm Timeline View allows visualization of Niagara Alarms and Niagara Analytics. The timeline chart improves upon a typical tabular view and enables better visualization of alarm frequency and correlation between alarms. This chart supports filtering of the data to view alarms from specific sites or specific priorities.
Clicking on an alarm will bring up an alarm details page as seen below.

Clicking Acknowledge will set the state on the Niagara alarm to "Acknowledged" and Acknowledge Series will acknowledge all alarms of the currently selected series in batch. The visual timeline representations shown in the Alarm View will also disappear when the corresponding acknowledgements are made.
