Checkmk vs. Nagios Core vs. Qualys VMDR

In our organization which is a mash up of different hardware, software it was important to use an independent tool that wasn’t linked to one manufacturer incase a piece of hardware was dropped from support for example, we also value open-source software highly in our field. It’s important to in our IT environment to be able to customize and tweak software that we run. We don’t use the cloud monitoring aspect so Cannot comment on that side of the software.

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 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.

• 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.

Very helpful software and I highly recommend to have on hand as a tool for testing, troubleshooting, and monitoring.

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.

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.

Overall Checkmk is a great product that is made and ran by a European company that is open source and highly customizable, great support if needed. On prem support is a must for our organization which Checkmk supports. Our organization has been using Checkmk for over 5 years now Performance of the software runs excellent on its own Linux server, for any company with a good Linux admin, you can have a lot of un tweaking and creating custom checks for every aspect of your environment.

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)

Checkmk free version is far superior to PRTG free version. For the paid versions PRTG was more efficient and easier to use. Checkmk provides unlimited services on their free version while PRTG is limited. We like to use the free version to avoid monthly or annual costs while still utilizing the same SNMP features.

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.

MOSTLY good - but as noted having all features purchased on portal only - nothing that is not purchased.

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