Nagios Core vs. Nagios XI vs. Zabbix

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.

If anyone looking for the monitoring system for the infrastructure this is the go-to tool which monitors all infrastructure related components from server health to Networking and update us with mails and can be easily integrated with multiple other tools as needed for example PagerDuty , Also this suits good both on premises and cloud environments as well. If we are managing complex environment this tool for monitoring is best one.

Zabbix is great for monitoring your servers and seeing alerts when the system uses too much CPU or memory. This allowed the system Engineer to be proactive and add resources to these systems to avoid interrupting the services. Especially servers running operations applications and services. This is one of the best usages for Zabbix.

• 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.

Incentivized

• Network monitoring.
• Database monitoring.
• Windows Server monitoring.
• Cluster Service monitoring.

• Collecting hardware data - CPU, Memory, Network, and Disk Metrics are collected and reported on.
• Flexible design - It is very easy to build out even very large environments via the templating system. You can also start where you are - network monitoring, server monitoring, etc. and then build it out from there as time and resources permit.
• Provides a "plugin architecture" (via XML templates) to allow end users to extend it to monitor all kinds of equipment, software, or other metrics that are not already added into the software already.
• Very complete documentation. Almost every aspect of Zabbix has been documented and reported on.
• Cost - Zabbix is FOSS software and always free. Support is reasonably priced and readily available.

• 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.

Incentivized

• Robust, but visually old interface. Requires a lot of work to become presentable.
• Small selection of dashlets to construct new views.
• No MS Azure monitoring ability, nothing for “as service,” very limited Amazon cloud monitoring abilities.
• Questionable price politics (could make it a lot less for developing markets to actually increase use of the product and R&D budgets).
• No report designers nor the ability to create new reports. No changes in this area for years.
• Overall lack of new developments, making this product more and more outdated.

Incentivized

• 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.

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.

This tool has been has been of great use and learning , offering exceptional ease of use, scalability, and detailed reporting. It has a lot of customization options and proactive monitoring which have significantly improved our infrastructure management.It's UI & functions are good. Also has built in templates for various end points.It also provides graphical reports. With a Dashboard you can monitor easily

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.

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.

We
are using Nagios XI in our organization primarily for monitoring all our
application servers and databases, this is helping us in addressing all the
infrastructure issues in advance by alerting us when it any server hits the
threshold as per the initial parameter setup also it has free tier which helps for small scale applications monitoring to save some expenses.

Incentivized

I think every organization, especially the IT department, needs a tool like this. I know of another product like Zabbix that gives a similar or the same solution, but its range makes it very useful. You can see almost all the device info in one place: disk usage, disk space, network usage, etc.

Never seen any such outages with Nagios XI till day it was available all the time working as expected

Incentivized

Performance wise it does its best job we monitor more than 500 Servers and we use this tool for Analysis also so never felt any lag

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.

Nagios XI support has plans to offer the following features:

• Access to knowledgeable IT professionals – including support staff and developers.
• Access to customer-only tutorials, documentation, and content in the Nagios Library.
• Access to customer-only boards on our support forum for expedited assistance.
• Access to customer-only email support for fast, confidential assistance.
• Discounts on future license purchases.

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.

I have been participated in the few implementations, and I would say its bit complex when its come to initial setup once its set post that its easy to manage

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.

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].

Cost efficiency is the main reason which we opted [for] Nagios as we were previously using IDERA tool with comprehensive database monitoring solutions, but the slow performance we are getting while monitoring the instance of the database.

We're using the Solarwinds suite as our global monitoring standard, but it is very complex and its licensing model makes it difficult to monitor a wide range of technologies. So, we're using Zabbix as a complement on our monitoring process. Zabbix is a way more flexible and has free integrations to a wide range of technologies. It is also more 'user friendly' and easy to manage.

Incentivized

We have installed Nagios XI for our monitoring system and with this we are managing around 600 servers in total and not seen any major issues with its scalability we can scale it as much as we require and also installed on various applications servers and working as expected
