Nagios XI vs. Sensu, by Sumo Logic

If anyone looking for the monitoring system for the infrastructure this is the go-to tool which monitors all infrastructure related components from server health to Networking and update us with mails and can be easily integrated with multiple other tools as needed for example PagerDuty , Also this suits good both on premises and cloud environments as well. If we are managing complex environment this tool for monitoring is best one.

• 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.

Incentivized

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• Overall lack of new developments, making this product more and more outdated.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

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.

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.

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.

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

• Very good ROI.
• Good results as capacity mgmt tool.
• Good results as application monitoring tool.

• 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.
