Better than Nagios, but not by much, and only if you have a lot of time and DevOps

Sensu was used for infrastructure monitoring by our internal IT team. We had been using Nagios for our monitoring but figured out fairly quickly that, even for a small business like ours, it doesn't really scale, and Nagios isn't really designed for today's age of containerized and cloud-based workloads.
  • 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.
Sooner or later, companies are going to figure out that there's more to monitoring than what Nagios can provide. For those that want to dip their toe in the water and still provide backward compatibility with a legacy Nagios environment, Sensu is a good choice.

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.
Sensu's customer support was always willing to work with us but never really seemed to learn much from our experiences. I think they get a lot of customers with DevOps IT teams that are willing to put in a lot of elbow grease to get the most of Sensu's architecture.

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.
