Datadog users are applying the "data-driven" philosophy beyond just infrastructure and applications, using monitoring to gain visibility into various aspects of their lives, such as beer consumption, sleeping, restroom availability, and energy use. For example, a Datadog user set up a system to monitor the temperature and quantity of beer in his office kegerator, while another group of engineers built a bathroom monitoring system using door sensors and Raspberry Pis. Some users are also using monitoring to track their sleep patterns and air quality, with one user leveraging DataDog's integration with the Sense from Hello to combat mold in his bedroom. Additionally, Datadog users have created voice interfaces like Alexa integrations to interact with devices without needing dashboards, demonstrating the versatility of the platform beyond traditional use cases.
