The Red Hat Ansible Automation Platform (acquired by Red Hat in 2015) is a foundation for building and operating automation across an organization. The platform includes tools needed to implement enterprise-wide automation, and can automate resource provisioning, and IT environments and configuration of systems and devices. It can be used in a CI/CD process to provision the target environment and to then deploy the application on it.
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].
Centreon has some added benefits to Nagios, mostly in how configurations are made and data is presented. Nagios is perhaps more reliable because of its simplicity. They are both based off of Nagios, so they are similar in many ways, but Centreon adds some of their own …
I haven't thought of any right now other than just doing our own home-brewed shell scripts. Command line scripts. And how does this compare? It's light years ahead, especially with the ability to share credentials without giving the person the actual credentials. You can …
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.
The thing I mentioned earlier where we're constantly dealing with federal regulations or new agents that they want us to install and deploy and just getting those out in a consistent manner in a canned installation via Playbook is ideal
Makes it easy to create and share automation in one central hub.
Ansible content collections give me the ability to reuse code, making it rapid to carry out complex IT processes.
Event-driven automation allows me to reduce manual tasks: it is rapid to know which action to take and respond automatically by receiving events from external apps automatically.
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.
Workflows should have more flexible paths than just success or failure.
The upgrade process can be challenging with differences in security and environment.
There is an opportunity to add CICD functionality into the tool.
For development, it would be nice to have the option of editing a repo directly from AAP to allow quick tests/reruns. Then, allow it to push the updates back or create a new branch/PR in GitHub.
The RBAC is good but could use improvements. One example would be an option that allows admins to assume the access of another user to validate it works as expected.
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.
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.
Great in almost every way compared to any other configuration management software. The only thing I wish for is python3 support. Other than that, YAML is much improved compared to the Ruby of Chef. The agentless nature is incredibly convenient for managing systems quickly, and if a member of your term has no terminal experience whatsoever they can still use the UI.
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.
There is a lot of good documentation that Ansible and Red Hat provide which should help get someone started with making Ansible useful. But once you get to more complicated scenarios, you will benefit from learning from others. I have not used Red Hat support for work with Ansible, but many of the online resources are helpful.

AAP doesn't truly stack up against any of the products mentioned except for Aria Automation. But, it is extensible and open and has a lower cost to entry.
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.
