Likelihood to Recommend 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.
Read full review If you are looking for a software that looks decent but is not something you truly rely on, this is it. I have had bad experiences with IBM Tivoli Monitoring reporting on system errors that were not evident on the systems themselves at all. There is a lot of specific alerting you can set up which is nice.
Read full review Pros 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 The GUI is easy to read. The software is fairly easy to configure. Almost real-time. Read full review Cons 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 The software is not reliable at all. Reports errors that are false-negatives. Hard to configure alarms/alerts. Bulky installation (takes up quite a bit of space). 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 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 We selected IBM Tivoli Monitoring as a bundle deal, other than that I would have probably gone with another vendor. We use Brocade Network Advisor for our SAN also which I would suggest to anyone over this software. The software has not been that reliable for me since we started using it.
Read full review Return on Investment 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 I would not purchase this again. Other software monitoring tools have been more reliable and easier to manage. Difficult to manage, if you patch the server the software is installed on and have to reboot it, IBM Tivoli Monitoring does not come up clean. Read full review ScreenShots
