Hi all, I've just developed a voice application for Amazon Alexa and Google Assistant and I would like to track user data from it. This is a trivia game so I would like to know how many matches user has made daily, how many questions have been answered and so on. What online service do you use? I would like to find a service that allows me to send data via API or via an exposed JSON and then I can configure the service's dashboard displaying data. A friend suggested me to combine Elasticsearch with Grafana. What do you use?
