Please have a look here: [Cumulocity IoT Web Development Tutorial - Part 3: Query data from Cumulocity IoT](https://community.cumulocity.com/t/cumulocity-iot-web-development-tutorial-part-3-query-data-from-cumulocity-iot/7678#query-data-using-c8yclient-4)

The c8y/client comes with an AlarmService:  
[http://resources.cumulocity.com/documentation/websdk/client/classes/alarmservice.html](http://resources.cumulocity.com/documentation/websdk/client/classes/alarmservice.html)

So you can easily query any data (also alarms) with it and visualize that data accordingly.
