"We needed something more dynamic than the old host-based Nagios style monitoring for our rapid deployments and teardowns. Sensu was the first and only tool that we ended up demoing because it worked that well and integrated so well with our configuration management. We have 4,500 machines in production, and pretty much all of them are Linux, Windows, or AIX boxes. Sensu lets me sleep more at night."
"We support millions of gamers on thousands of nodes. We had over 100K services across five different Nagios [deployments]. Morale on our team was incredibly low, and turnover was incredibly high. So I went to senior leadership and asked if I could do something about it. We took a look at a ton of different offerings in the space and to be honest, there was only one answer: Sensu. It supports Nagios checks out of the box, it's incredibly extensible, and it's designed from the ground up for scalability."
