Checkmk vs. Nagios Core vs. Zabbix

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.

Because we spread out in different locations, we can't always know the status of our devices. Zabbix solves this issue for us. As soon as we see an alert that the remote site is down, we can solve it right away. I can't think of a scenario where it was less appropriate for us.

• Network and server status alerts if a device is in a down state.
• Gives you the top view down of your entire network infrastructure.
• It can be customized to your exact needs.
• You have two options of agentless and agent monitoring.

Incentivized

• Alerts; Zabbix allows deep customization of conditions and alerts giving you the ability to perform nearly any scripted action in a variety of scenarios
• Inventory; having one place to see a list of all on-going problems and list of servers within your organization is critical
• Graphs; screens or graphs showing customizable and color-coded historical usage is a necessity in any monitoring software

• Ease of Use
• Upgradability

• 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.

• Creating an alert & its trigger can be made easier.
• More VM-based data collection counters should be introduced to have better VM monitoring.
• The raw counters collection agent in every node is relatively weak. It goes down often, which needs more stability.

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.

It is free. It didn't cost anything to implement (other than my time and the cost incurred for it) and it is filling a badly needed gap in our IT infrastructure. Support is available if we have issues and can be done annually or paid for on a per incident basis as needed. Expansion, updates, and all other future lifecycle activities are likewise free of cost, so as long as someone is able to implement/maintain the software (and the OSS project is maintained) then I imagine the company will never leave it.

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.

Well i find the tool quite useful for my daily network monitoring purpose. We get the alerts easily through SMS which saves us lot of our times and effort. The tool is highly customizable which i mentioned earlier which helps to create different alert criteria for different device or system.

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.

The setup is the most time-consuming portion of using zabbix. It takes a lot of effort to shape it into a usable format and even then it can get very messy. It's not exactly intuitive and as mentioned the UI seems a bit antiquated. If I was to roll out a monitoring solution from scratch, I'd probably look for alternatives which are easier to use and maintain.

We are a mainly Windows environment, so it would be useful if we could have used Active Directory to deploy agents. As of version 4.2, Zabbix has announced a new agent MSI file to allow exactly that. Unfortunately, we didn't have that option. Also, for Linux and MAC deployments, there is no simple way to deploy that. Using remote scripts you may be able to create something, but most places will opt for either SNMP (agentless) or manual installation of agents to add to Zabbix. A way of deploying agents via discovery would go a long way to helping in the adoption of the tool.

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.

The software's I mentioned are great, but they are overpriced comparing to Zabbix while it's a free open-source application. The value its adding has high price than any other free open-source apps. the monitoring and alerts details and the friendly user interface is stacking up against any other apps in the web.

• 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.

• Zabbix has had a positive impact on uptime of our external facing website. Users don't always call up our Customer Service team to report that something is down - sometimes they just abandon the website all together. By having a monitoring solution that tells us when things are down before customers do, we are able to respond quickly and avoid losing visitors and ultimately sales.
