Sensu is an Infrastructure and monitoring / telemetry solution. There are big sites using it such as Yahoo, Yelp, Cisco, and Tesla. Sensu provides standard solutions for monitoring and alerting.Which I can say is okay. However If you have been following my Telemetry and Microservices blog posts series( part1 and part2 ) you will see sensu is not ideal for other use cases like: * Dynamic Thresholds / ML * Infrastructure Tracking * Canary Because Sensu it doesn't have a Time Series database. You can use Sensu with Graphite or InfluxDB to work around it. However IMHO the solution it would be: have collectors(collectd) to get basic HOST metrics plus app instrumentation and them make checkers that do queries over the TSDB.
