Likelihood to Recommend I would recommend IBM Instana based on its strengths in automating application performance monitoring, dynamic tracing, and its ability to handle modern, containerized environments effectively. The automatic discovery and mapping feature, along with AI-powered anomaly detection, provide valuable insights for proactive issue resolution. However, I would consider factors such as the organization's specific technology stack, scalability requirements, and budget constraints. Conducting a thorough evaluation, including a trial or proof of concept, would be essential to ensure that IBM Instana aligns with our unique needs and contributes positively to our technology and business objectives.
Read full review Nagios monitoring is well suited for any mission critical application that requires per/second (or minute) monitoring. This would probably include even a shuttle launch. As Nagios was built around Linux, most (85%) plugins are Linux based, therefore its more suitable for a Linux environment.
As Nagios (and dependent components) requires complex configurations & compilations, an experienced Linux engineer would be needed to install all relevant components.
Any company that has hundreds (or thousands) of servers & services to monitor would require a stable monitoring solution like Nagios. I have seen Nagios used in extremely mediocre ways, but the core power lies when its fully configured with all remaining open-source components (i.e. MySQL, Grafana, NRDP etc). Nagios in the hands of an experienced Linux engineer can transform the organizations monitoring by taking preventative measures before a disaster strikes.

Tracing the end-to-end journey of an event and also categorizing by technology and Endpoints Built-in and custom alerts help to monitor almost all of scenarios without much additional configuration. Ability to create Applications to logical group important flows Read full review Monitoring of services is one of the biggest benefits for our company. Being able to respond in a timely fashion keeps business smooth. Hardware and device monitoring are easy to set up with proper parameters. Notification to key staff to be able to respond quickly makes issues go away faster. Read full review Cons I believe that the "live" option in monitoring does not truly update the status in real-time, thus I must manually update to feel comfortable. The call analysis tool might be improved, third-party resources are restricted, and the pricing is slightly more than competitors in comparable categories. Read full review Nagios could use core improvements in HA, though, Nagios itself recommends monitoring itself with just another Nagios installation, which has worked fine for us. Given its stability, and this work-around, a minor need. Nagios could also use improvements, feature wise, to the web gui. There is a lot in Nagios XI which I felt were almost excluded intentionally from the core project. Given the core functionality, a minor need. We have moved admin facing alerts to appear as though they originate from a different service to make interacting with alerts more practical. Read full review Likelihood to Renew We're currently looking to combine a bunch of our network montioring solutions into a single platform. Running multiple unique solutions for monitoring, data collection, compliance reporting etc has become a lot to manage.
Read full review Usability The Nagios UI is in need of a complete overhaul. Nice graphics and trendy fonts are easy on the eyes, but the menu system is dated, the lack of built in graphing support is confusing, and the learning curve for a new user is too steep.
Read full review Support Rating I haven't had to use support very often, but when I have, it has been effective in helping to accomplish our goals. Since Nagios has been very popular for a long time, there is also a very large user base from which to learn from and help you get your questions answered.
Read full review Alternatives Considered We chose IBM Instana for several reasons, and the most important one is that we didn't have to make changes in our code for nearly all of our applications for it to work. We are happy with the decision we made to use IBM Instana.
Read full review Because we get all we required in Nagios [Core] and for
npm , we have to do lots of configuration as it is not as easy as Comair to Nagios [Core]. On
npm UI, there is lots of data, so we are not able to track exact data for analysis, which is why we use Nagios [Core].
Read full review Return on Investment System down time is shortened as our ability to troubleshoot issues goes up. Potential downtime is stopped as we are able to slow down calls/ availability of calls in response to monitoring the dashboard. We are able to react to issues quickly through the smart alert system rather than manual checks. Read full review With it being a free tool, there is no cost associated with it, so it's very valuable to an organization to get something that is so great and widely used for free. You can set up as many alerts as you want without incurring any fees. Read full review ScreenShots
