"We are purely hosted in AWS. Production just surpassed 12,000 nodes. Hardcoding hosts into flat files on disk and then having a bunch of Perl scripts read in a flat file from disk was really a bottleneck [with Nagios]. The automatic registration and deregistration of hosts [in Sensu] was essential to allowing us to be flexible in AWS. We looked at DataDog, various forks of Nagios, and Prometheus, but ultimately we landed on Sensu."
“Sensu stands out because you can customize it to check and alert on literally whatever you want. Plus, I’m confident that all our services are monitored, and that helps me sleep well at night.”
