Nagios XI

Nagios XI is suitable for inexpensive and very detailed monitoring of the physical hosts and VMs. Both Windows and Linux. This would require configuring 2-3 ways of monitoring for the same set of hosts and some time spent to fine tune the configurations. It may also be used for SQL and Apache front-ends such as Tomcat, Glassfish, etc.

Sensu

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.

Pros

Nagios XI

  • Nagios XI has an exclusive feature of bulk modification of attributes that help in monitoring the same set on monitoring modules on a newly set up environment.
  • It allows you to monitor many network devices, such as switches, routers, servers, and is helping to monitor network performance and track traffic on the network interface.
  • The audit trails feature allows us to scrutinize the modification or setup.

Sensu

  • Unique concept as a "monitoring router" that can tie services together.
  • Backward-compatible with Nagios environments.
  • More of a DevOps focus than Nagios.

Cons

Nagios XI

  • Robust, but visually old interface. Requires a lot of work to become presentable.
  • Small selection of dashlets to construct new views.
  • No MS Azure monitoring ability, nothing for “as service,” very limited Amazon cloud monitoring abilities.
  • Questionable price politics (could make it a lot less for developing markets to actually increase use of the product and R&D budgets).
  • No report designers nor the ability to create new reports. No changes in this area for years.
  • Overall lack of new developments, making this product more and more outdated.

Sensu

  • 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.

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.

Alternatives Considered

Nagios XI

Nagios XI is better supported vs SolarWinds, needs less manual administration work vs Datadog and a lot less expensive for a long as you are willing to compromise on the look and some functionalities. Moreover, SolarWinds database design prevents one from storing any meaningful data for an extended period of time (creating averages of the averages of the averages), where Nagios could be set for keeping years of detailed information without large storage or the overutilized DB engine. In both Datadog and SolarWinds trials we could not get answers to many of our questions, configure working solutions out of the box by using the inline documentation. Nagios XI does not have limitations, offers such as AppOptics impose on the customers (making it very expensive and absolutely not a real life product). Overall, Nagios XI is a great tool, requiring a lot of R&D “yesterday” to make it beat all the competition on all fronts. That is assuming you have an extensive knowledge in the many areas of IT (thus knowing what should be monitored and how to interpret the data).

Sensu

We initially compared Sensu to Nagios XI. Nagios has languished for years and clearly wouldn't scale well without a lot of effort, while Sensu's architecture was clearly designed to be better at scaling horizontally.

Return on Investment

Nagios XI

  • Reduction of at least 10% of false alarms.
  • Increased network traffic by 5%.
Eduin Zuloaga | TrustRadius Reviewer

Sensu

  • Standing up the Sensu Go server took very little effort.
  • Setting up and maintaining the build processes and deployment logic for Sensu assets and checks was somewhat exhausting and resulted in lower adoption among non-DevOps IT.
  • The limited web interface resulted in lower adoption among non-DevOps IT.
