Watch Cameron Soleimani of Uber uses “Sensu as a service” for multiple teams across Uber to monitor their AWS and VMWare deployments. With Sensu, they know about alerts immediately which helps them fix problems and doesn’t let things build up. They find Sensu very customizable, and love all the plugins and the community that contributes to them.
Watch In this CNCF webinar, Sensu CEO and co-founder Caleb Hailey will review some of the existing and popular patterns for monitoring Kubernetes (like Prometheus), and what gaps remain outstanding, especially when it comes to monitoring the applications running on Kubernetes. He’ll go over best practices for monitoring workloads on K8s, including the sidecar pattern for monitoring.

- Cloud agnostic monitoring.
- Open source
- Container monitoring at the highest level.
- Monitoring plugins can be easily created.
- Cannot be solely used for tracking metrics over time.
- Not a very good UI.
- Well suited for raising pagers when you have count-based metrics.
- Well suited for threshold-based metrics.
- Not well suited for tracking events over the day, since graphs and other visualizations are missing.
- Unique concept as a "monitoring router" that can tie services together.
- Backward-compatible with Nagios environments.
- More of a DevOps focus than Nagios.
- Terrible documentation that assumes you're already an expert in everything that Sensu can do.
- Significantly more work than Nagios to get basic checks on and configured.
- Web interface is primitive and not even on the same level as Nagios XI.
- Large price hikes after Sensu Go was released.
It's mainly for businesses that want more than Nagios but don't want to take the full plunge with something radically different and metric-based such as Prometheus.
Having moved to metric-based monitoring so far as I'm able, I can say with confidence that it's far better than what Nagios or Sensu provide.
However, despite explaining my continued disappointment with their documentation and the overall flow of the product, I never got much more than a "sorry" and a notice that their documentation was open source if I wanted to contribute to it.
The problem, of course, is that you can't document what you don't understand. I'm a former technical writer, so I know that better than most.
