Icinga
Chose Icinga
PRTG was the solution that was implemented before. As Icinga is Open Source we saved the licensing fee, as we ran out of free checks. I also had knowledge in Icinga so we switched over.

Nagios is inferior to Icinga in my opinion, as Icinga has the better Web UI, which I use the …
Chose Icinga
Installation and initial configuration is straight forward. However the system can grow in complexity very quickly, if not managed correctly.
Chose Icinga
Icinga was initially a fork of Nagios. Over time, the configuration language was replaced with something more programmatic. This configuration language is one of the big sellers of this product. It allows flexible, quick configuration of large sets of hosts and services with …
Chose Icinga
While Icinga holds its own against old stalwarts like Nagios and Zabbix, it simply can't compete with the new generation of SaaS service/server monitoring software in terms of ease of use, feature-completeness, integration with things like Cloudwatch, CloudHealth, New Relic, …
Chose Icinga
There are two main competitors of Icinga in my opinion, Nagios, and NetFlow based monitoring solutions. Both are good, Icinga, is a more refined version of Nagios with a much better API and backwards compatibility to the platform. If you are running Nagios, you can transfer …
Chose Icinga
Icinga is better than Nagios because of its nicer user interface. New Relic can monitor CPU/memory and disk usage, but it's more of a performance and application troubleshooting tool rather than monitoring.
Nagios Core
Chose Nagios Core
We selected Nagios because of the size of its community. We've used some of the others in the field over the past few years, Nagios had the best features out of the box coupled with it's following made it an easy selection.

Icinga GmbH
Icinga is a world-class monitoring system. It can be used for most general monitoring situations. It is not a silver bullet, however, and there are instances where domain-specific monitoring systems are necessary. However, the output from those monitoring systems can be funneled into Icinga as a central monitoring and alerting system.

Nagios Enterprises
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.

Qualys
Qualys VMDR is best suited for larger companies with a very large IT asset footprint. Qualys VMDR is not suited for businesses that are small and upcoming as the price for the tool is very expensive and could be a budget sink if not used properly. In our organization we use the Qualys VMDR dashboard and reporting in order to collect any vulnerabilities we miss during our routine audits to ensure that our environment is stable and protected for attacks.

Cons
Icinga GmbH
  • High learning curve, setting up Icinga from scratch can be a bit of a challenge starting out.
  • If the io2db process fails you UI stops updating, which can be very frustrating.
  • There is no simple mechanism for adding new hosts and services through the web UI, it's all very config-file based.

  • 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.

  • Qualys VMDR can definitely improve on its reporting of assets as we have caught devices not captured in the Qualys VMDR scans.
  • We would like to see an improvement on the dashboard interface as it is faulty sometimes.
  • Qualys VMDR should focus on more competitive pricing as it is very expensive.

Icinga is a solid solution which does everything it promises. It is backwards compatible with most Nagios instances, making the transition very easy. Once you get the hang of installing new plugins and editing configuration files expanding its monitoring capabilities are easy.

Next to Veeam (which is a tremendous product for backup/DR) this is the best service/software I have used in the past three decades. Should be called the Swiss Army Knife of security.

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.

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.

This is iron but I am giving it 5 star and I can give more If I can do because they are best in support. So once you own this product they will assign a dedicated support for you and when you are under the weather with anything just connect them with anything call, ping or ticket they will come like Genie.

Not really - the integrations via connectors is not heavy lifting. Any complexity has to do with a service that requires more steps (i.e. AWS/GCP)

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].

It is a very similar tool but Qualys VMDR is much better when it comes to reporting and solutions provided. Asset management is really good in Qualys VMDR. Qualys VMDR support is really quick , you can get a TPM if you run into any issues. Qualys VMDR has wide variety of scanning options which lacks in tenable.

Outside some pretty arcane apps or OS this is painless. The problem - and self-inflicted - is that older stuff is not supported.

Return on Investment
Icinga GmbH
  • With one check you know which applications are faulty e.g. after an upgrade. Which is big time saver
  • You easily detect outages ion the applications so that your customer ideally does not even realize there was an outage.
  • Detect if the environment does deliver the same result as in the same time as before to detect shortages.
  • Additional information when debugging. Saved us several hours where we could simply point to a database which was slow.

  • 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.
