Checkmk vs. Nagios Core

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 is simply a very configurable and rock solid monitoring engine. For these reasons I would recommend it to any IT professional in any medium to large organization where creating custom checks and programming ones custom needs into the configuration is practical. I would be more hesitant to recommend it as a first monitoring solution for a small business which is usually accompanied by a less experienced and/or more time constrained admin.

• It's built by engineers for engineers so setting it up and configuring it is relatively complicated. It could really use a simplified configuration approach, or a GUI to set it up instead of editing config files.
• I'd like to see the option to have service notification settings inherited from the host setting notifications. They have to be set up separately but they are often the same, so it would be nice to have less redundancy.

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.

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.

We moved over to Checkmk from Nagios which felt like a natural evolution at the time as the raw version is based on Nagios, I vaguely not having any major issues moving over at the time. We still use the Raw version but we are planning to move to the enterprise version in the next 6 – 12 months as our needs expand.

We have tested several other monitoring products which were able to monitor the basic matrix (Memory, DiskUsage, CPU%, UpTime, Running Service Status, Port 80 Up/Down). Although some offered far better UIs, they lacked the ability to monitor ANYTHING. Zabbix, being the only contender worthy of competing, is a good alternative to Nagios. We also tried Zenoss Core & OpenNMS which were good enough for non-Linux engineers to get started with. OP5 was another service-oriented monitoring solution we evaluated. Apart from Nagios, Consul is heavily used to monitor & register the micro-service systems & end-point URLs. Due to the time invested (9+years) in Nagios, we were able to get more components installed/configured easily than alternatives.

• avoid downtime
• Plan updates based on usage of a VM or network switch to avoid impacting users
• User satisfaction increased due to less visible downtime or issues with our IT infrastructure.

• 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.
