Nagios XI vs. Sensu, by Sumo Logic

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.

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.

• Network monitoring.
• Database monitoring.
• Windows Server monitoring.
• Cluster Service monitoring.

Incentivized

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

Incentivized

• 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• Overall lack of new developments, making this product more and more outdated.

Incentivized

• Cannot be solely used for tracking metrics over time.
• Not a very good UI.

This tool has been has been of great use and learning , offering exceptional ease of use, scalability, and detailed reporting. It has a lot of customization options and proactive monitoring which have significantly improved our infrastructure management.It's UI & functions are good. Also has built in templates for various end points.It also provides graphical reports. With a Dashboard you can monitor easily

We
are using Nagios XI in our organization primarily for monitoring all our
application servers and databases, this is helping us in addressing all the
infrastructure issues in advance by alerting us when it any server hits the
threshold as per the initial parameter setup also it has free tier which helps for small scale applications monitoring to save some expenses.

Never seen any such outages with Nagios XI till day it was available all the time working as expected

Performance wise it does its best job we monitor more than 500 Servers and we use this tool for Analysis also so never felt any lag

Nagios XI support has plans to offer the following features:

• Access to knowledgeable IT professionals – including support staff and developers.
• Access to customer-only tutorials, documentation, and content in the Nagios Library.
• Access to customer-only boards on our support forum for expedited assistance.
• Access to customer-only email support for fast, confidential assistance.
• Discounts on future license purchases.

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.

I have been participated in the few implementations, and I would say its bit complex when its come to initial setup once its set post that its easy to manage

Cost efficiency is the main reason which we opted [for] Nagios as we were previously using IDERA tool with comprehensive database monitoring solutions, but the slow performance we are getting while monitoring the instance of the database.

Incentivized

Have used New Relic and Sematext Cloud for APM and for tracking over days and visualizing the issues. But those are very expensive as compared to Sensu.

Incentivized

We have installed Nagios XI for our monitoring system and with this we are managing around 600 servers in total and not seen any major issues with its scalability we can scale it as much as we require and also installed on various applications servers and working as expected

Incentivized

• Reduction of at least 10% of false alarms.
• Increased network traffic by 5%.

Incentivized

• Can easily understand and extend use-cases to under server capabilities.
• Can use it to scale well.
• Can help in efficient resource planning.
