Ideal for monitoring AWS services and workloads. We have several of our websites entirely hosted on AWS and we're able to get a Grafana dashboard of all the relevant metrics from CloudFront, S3, EC2, RDS, and Elastic Beanstalk. This can be set up within the hour or templated on your code for infrastructure (we do this with terraform & cloud formation). By design, it isn't suited for non-AWS workloads.

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.

Pros

Amazon CloudWatch

  • Managing log retention periods is very simple with CloudWatch, and can be configured on a per-group basis.
  • Monitoring host performance is very easy when coupled with the CloudWatch Agent on an EC2 instance. A simple installation and configuration replaces an entire 3rd-party host monitoring stack.
  • CloudWatch is flexible enough for not just host monitoring, but application monitoring as well. It's easy to pipe local logs up to CloudWatch and extract structured data in order to monitor and set alerts on custom app metrics.

  • 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.

Cons

Amazon CloudWatch

  • Its limitation on only Amazon resources.
  • Cost is higher.
  • Lack of ability to create graphs on distinct counts and histograms which can make it hard quickly identify specific IP addresses that have a high request volume in a certain period. We have worked around this but a feature on the dashboard would be nice.

  • 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.

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.

Nagios is an open source product, which means most of the support comes from the community. Unless you purchase one of the paid products, such as Nagios XI, you can't really expect to see any level of meaningful or traditional enterprise level support. But there's also a distinct lack of account management for the open source product as well, so there isn't a path inside the company typically for customer support.

Alternatives Considered

Amazon CloudWatch

I can only speak to how it's positively benefited my organization. The problem was that hosting in-house servers is no longer a cost-effective solution vs. containerization in the cloud. But once you rely on hosting servers in the cloud you need a tool to manage every aspect of that including log monitoring, resource utilization, and application performance. Amazon CloudWatch is exactly the tool you need.

The cost is considerably better. Others are probably more complete and even overkilled if all you're looking for is simple SNMP alerting and reporting. If you're looking for integrated analytics or more complex reporting/alerting, there might be better options. Nagios also provides basic NetFlow monitoring in a separate module (also purchased separately) but I don't believe it's all that intuitive and might require additional efforts to set it up compared to other NetFlow tools.

Return on Investment

Amazon CloudWatch

  • CloudWatch is liked by the IT guys, in that it makes their job easier. Whether that actually is a positive ROI is debatable. It doesn't seem like it.
  • CloudWatch could have a positive ROI in the sense that IT professionals consider it an integral tool to streamline their management of IT resources.
  • Cloud is not a positive ROI in the sense that it doesn't appear to have saved any money on the personnel or software side.

  • The ROI is great since Nagios is free and the only thing that it requires is dedicating a few staff members' time to learn.
  • Overall our IT operations reliability has improved greatly.
  • Nagios has been able to meet all our objectives and goals by showing clearly where our reliability issues are.
