Harrison Bulley - PeerSpot reviewer
A stable, scalable and cost-effective solution that helps with inbuilt scripts for easy modification
I think the software is quite good, but we have had problems with getting it to recognize certain areas and amend certain checks, where we needed so we would have to create backend scripts for those checks. Though, being open source, it has the support to create backend scripts, it would be better to have these scripts in-built.
Amir  Said - PeerSpot reviewer
Effective alerting enhances network monitoring experience with an easy setup
We love Nagios XI due to the fact that JPS Web is very useful. JPS monitors the modem and performs switching, monitoring the computer, and performing switching. We implement some applications and traffic monitoring. The alerting system is very effective. For instance, if we have an alarm on some RAM storage if the traffic is cut or dropped.
ASM Naushad Alam - PeerSpot reviewer
Allows any number of customizations but lacks functionality for finding root causes
We have not yet purchased the commercial version so have a lack of technical ability. We do not yet fully know the key points or key features of the solution. We just use what we use along with WhatsUp Gold. Based on our use only, stability is rated a seven out of ten.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"Macros and the ability to connect it to Google Maps are valuable features."
"An affordable solution for small organizations to do basic network monitoring."
"The best thing about the solution is how it highlights errors, the issues, and what needs my attention. The solution directs me to areas that I should look for first."
"I like the ability to amend and adjust things really easily, which is useful in a case where you could make it auto-discover and then set a template to say all of these applications or servers under this template have an automatic threshold set that you’d set up manually."
"The value of Icinga is that it has hundreds of plugins, so it's really easy to monitor pretty much anything."
"Icinga does the job and is fairly stable."
"There's a module called Icinga Director, which helps us configure the product using an intuitive interface through clicks instead of creating a text configuration. It's very helpful for us."
"The apply rules feature saves a lot of time."
"The features I've found the most useful are the plug-ins, the fact that you can connect almost everything to it. That's very useful."
"BPI: It allows defining peripherals to map business criticality for efficient monitoring, as required."
"Since this is an open source technology, if we are capable of writing the plugins in any scripting language, this product allows us to monitor anything we want."
"The most valuable feature is the monitoring of processes."
"The most useful aspect of this solution is the ability to customize it for the client agent."
"The dashboard allows you to see what's going on in the overall system."
"The ability to set up templates and groups of checks, as well as customize the checks themselves."
"An excellent solution that is easy and intuitive to implement."
"I use the solution to provide a perfect environment for remote connectivity with my clients."
"It's a flexible solution."
"It can send messages to our ticketing system."
"It meets my organizational needs. It's pretty easy to use."
"The template system in Zabbix is very beneficial as it saves time in configuration."
"The solution is stable."
"We use Zabbix to monitor our organization's IT infrastructure and workstations. We don't use Microsoft Intune since it's expensive. The tool's real-time alerting system has proved crucial for us, particularly when a new device joins a network that is not one of our own devices. It notifies us about the presence of this new device, allowing us to investigate further. Additionally, it alerts us about disk usage, memory usage, and the software installed on the machine."
"The most valuable features in Zabbix are those that help us overcome bottlenecks in CPU usage, as well as reduce memory delay. I know that we have only reached the tip of the iceberg of what Zabbix's features can do for us, and we have not used all of them yet."
 

Cons

"It needs Trap SNMP. I saw the documentation for Zabbix, that it has its own built-in product which handles SNMP traps, and there's nothing similar in Icinga or Nagios. I think this feature is most important for me."
"One thing that Icinga lacks is the capability to create advanced and customized dashboards within the tool itself."
"There is room for improvement in multi-tenancy. It's not perfect, not even really good. It's average, but it should be improved."
"We have found some problems with Nagios, and support isn't very responsive."
"I think the software is quite good, but we have had problems with getting it to recognize certain areas and amend certain checks, where we needed so we would have to create backend scripts for those checks. Though, being open source, it has the support to create backend scripts, it would be better to have these scripts in-built."
"The user interface should be improved."
"Icinga’s automation could be improved."
"The solution lacks many features important to higher-level IT management and network support."
"We'd like to see more integration capabilities."
"The product uses the backend as Perl and could be modified to a more lightweight solution like what's being offered by other vendors."
"The PNP4Nagios plugin not working easily with XI is an issue for me, because some open source monitoring plugins do not work out of the box. But in the end, you learn to live with it."
"Technical support is an area that needs improvement. It is not available 24/7."
"Open-source software is usually not user-friendly."
"The reporting structure could be more streamlined."
"The Configuration Wizard needs improvement, because not all vendors are present."
"The product could be optimized to improve the administrative user experience via the Nagios Core Configuration (NCC) GUI module."
"Zabbix is powerful, but it is difficult to understand initially. There are many things that can be improved, but we might not be using Zabbix to its fullest extent. The software has more features than we need."
"The reports are not great and should be improved."
"The integration of the product is not so easy, especially when it comes to the application database."
"There's a small module of APM, however, it is not an enhanced version. People usually ask for a full-fledged APM solution."
"When we have a problem, we have to do a lot of research to solve it."
"In terms of user-friendliness, large maps could be more interactive. We should be able to click on some areas and move some objects. It would make it simpler to see things while analyzing some dedicated parameters."
"The APM monitoring has room for improvement, although I hear that the new 5.2 version has some improvements in that area, and I'd like to give that a go. I would like to see a few more templates out there for different styles of monitoring. I use the Grafana interface for reporting. I would also like it to have an out-of-the-box ability to email reports. You can create reports, but to be able to email those reports would be really helpful. I've got users who are not interested in logging in and generating a report. They want it all pre-canned and sent to an email address. It would also be really handy if we could pin certain reports up onto platforms such as Teams or SharePoint. A GUI for the proxy server would be cool to have for debugging purposes and for the support teams to have a look at, but I don't know whether that's really feasible to do. I get enough from the log files themselves."
"Even though it’s such a powerful monitoring system, it would be more helpful if it had a flexible UI."
 

Pricing and Cost Advice

"Even though Icinga's financial cost is low, it is an expensive product regarding the resources required to maintain and operate it."
"This is an open-source solution with paid support."
"The solution is cheap."
"It is cost-effective, and the return on investment can be very interesting because the price is low."
"It's an open-source solution."
"The solution is free to use."
"We're using the free version of Icinga."
"The product is inexpensive compared to other DBM products."
"This solution is very expensive, at approximately $5,000 USD when I purchased it, which is why I haven't upgraded my version in several years."
"Nagios Core does not have any payment, but Nagios XI requires payment for the license."
"Licensing costs are reasonable."
"The pricing is high with separate licensing for the product and support."
"As it is not an agentless tool, I think it is expensive."
"For the cost of the commercial product and support, and taking into account the open source characteristics of it, I believe it is difficult to a better value."
"The licensing fees for this solution are approximately $3,000 USD per year."
"It is good to contact experts for advice about what is the best solution for your specific infrastructure and enterprise."
"Zabbix and Grafana are both open source products, we only needed to go to their website and download the application and we began to use them. The solutions are free."
"For pricing, it's free. We don't pay anything for it. They open-source the code, and people pay for support."
"It is open source. If you want to have a subscription or official support, you can pay for it. They have different plans, which are not that expensive. The plans are based on per monitoring server, not per monitored equipment. So, it is not at all expensive, and you can also live without the support if you want a cheaper option."
"Zabbix is a free solution but the support contact costs money."
"We were searching for an open source solution and Zabbix fit the bill because it is free and open source under the GPL license."
"I use the tool's free version."
"If you have 20,000 hosts, the support costs around €95,000 for a year."
"Its licensing is fair. It seems to be much cheaper than others."
