Battle tested at scale and trusted for production workloads by industry leaders.
“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.”
“The Sensu Community has provided Box.com engineers the ability to more quickly and reliably monitor their services—accelerating everything from debugging systems and auto-remediation to design decisions.”
“Monitoring services in a dynamic world like this is a difficult challenge. Sensu is the only open-source monitoring tool I’ve seen that is up to this challenge.”
“We have placed Sensu at the heart of our monitoring and alerting tooling, due to its flexibility, ease of adoption and stability.”
"We support millions of gamers on thousands of nodes. We
had over 100K services across five different Nagios [deployments].
Morale on our team was incrdibly 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."

"We use Sensu to monitor everything from physical nodes
and hardware within our data centers, to VMware, OpenStack, and

"We have a lot of different teams using Sensu to create
their own alerts. We are monitoring VMs in VMware and AWS instances.
We're not quite doing Kubernetes yet, but we will soon."
— Cameron Soleimani, Systems Engineer
"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."
— Jared Ledvina, Cloud Operations Engineer
"Ericsson is a company with over 100,000 employees, so
there are tons of Sensu [instances] everywhere. We’re focusing on
monitoring as part of our DevOps solution, and wanted to bring Sensu in
as the glue to bring all of the pieces together (like Prometheus and all
the different application monitoring solutions we’re currently
implementing). We wanted to have something that can funnel that into one
place, and Sensu seemed like the best fit."
— Travis Rowland, Lead DevOps Architect
"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."
— Christopher Sabo, Automation Engineer
"I’ve been using Sensu since about 2014. I’d recommend
Sensu because of its extensibility. There’s a lot of tools out there
that can do monitoring, but very few of them are frameworks for
monitoring. You could use Sensu as just a Nagios replacement, but it can
do so much more. It’s really about making sure things are up and making
sure our customers aren’t the ones telling us things are broken."
