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.
Harish Venkateshappa - PeerSpot reviewer
Useful online resources, customizable, and highly effective monitoring
The solution is useful for tweaking. However, there have been some negative experiences, such as limited report capabilities. The only report available is in PDF format, making it difficult for teams managing multiple servers to extract data in Excel format. The speaker recommends that the team improve the report capabilities to better serve users. If there are corrupt files the data can be extracted from them. Anyone who wants to see the performance of memory usage, such as whether it's at 80 to 90 percent, can use this tool. However, other tools can provide this information in two minutes, this tool is more time-consuming and the report it provides is not very effective for practical use. When it comes to reports, the tool falls short. During a recent call, it was noted that while the company has distributed servers across the globe, only the master server can accommodate the reports and events, causing delays. If other servers experience issues, the team cannot view the reporting or tag things, such as for troubleshooting purposes. If this aspect was improved it would be an excellent tool.

Quotes from Members

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

Pros

"Nagios XI helped me to draw the network and check for system failures."
"It's great for monitoring IT services infrastructure."
"The most valuable feature is the dashboard, where I can have a single screen that provides a summary for hundreds of servers."
"The installation is no problem. I've installed Nagios several times."
"Nagios is stable and it's easy to use the monitoring software, which is why we chose this product."
"This is a very good solution and it is simple to use, for any company."
"Though I downplayed the administrative NCC GUI, this is by far the strongest aspect of the Nagios XI product."
"Nagios is a custom API manager, and we can expose custom APIs for our integration. This is a great feature."
"It monitors and continuously tests everything that is of importance to you and your users. It could be everything from monitoring disk space to CPU usage to memory. It could include determining if the response time in your e-commerce platform is quick enough, or whether you have too many bounces from some of the pages on your website. You want to monitor anything that could cost you money or time or resources. You can do that with this system. It's very flexible."
"We can also observe whatever we want, and there are no limitations."
"OP5 Monitor is a great choice due to its being built on an open-source monitoring tool and provides ample opportunity for customization based on specific support requirements. It is also user-friendly and easy to manage with a wide range of plugins available for use. In comparison to other enterprise tools, such as Micro Focus, OP5 Monitor stands out for its features and cost-effectiveness, making it the best tool in the market. Customization is one of the key strengths of the tool and provides a lot of capabilities. Additionally, it is easy to find support and plugins for the tool through online resources."
"The API makes it pretty easy to integrate with any system."
"With limited hardware or a virtual machine, you can address a huge network, hundreds of thousands of elements that need to be monitored. Other commercial software is not on that level."
"The best feature is that it is very relatable, stable, and scalable. The logger is a part of the software, but it's not the most important point of it."
 

Cons

"The product's stability could be even better."
"The user interface needs improvement."
"The scalability of Nagios XI is scalable. However, it is not easy to do."
"The user interface needs improvement. Many tools have poor user interfaces, making them hard to manage and navigate."
"They need more documentation for the plugins."
"The installation and monitoring need improvement."
"Technical support is an area that needs improvement. It is not available 24/7."
"From an alerting point of view, some graphics and metrics don't work properly with Nagios XI as they do with Checkmk."
"IT environments today are in constant flux. This is driven by the newer cloud technologies such as Kubernetes and Docker, etc. The whole Nagios-based monitoring system that OP5 is created on top of, is based on a host-service model. There is a need for a strategy on what to do with more dynamic environments. There is some cool stuff going on in that direction."
"They need to improve the dashboard interface."
"The solution is useful for tweaking. However, there have been some negative experiences, such as limited report capabilities. The only report available is in PDF format, making it difficult for teams managing multiple servers to extract data in Excel format. The speaker recommends that the team improve the report capabilities to better serve users."
"The user interface is not what we are used to these days, and should be improved."
"We do not get performance reports properly."
"OP5 lacks some visualization, a feature that makes some other products nice. Op5 is built for purpose, which is fine, but if you compare it with some new products, the visualization is not so appealing, especially for management... If you don't need fancy visualizations, OP5 is fine."
 

Pricing and Cost Advice

"It is good to contact experts for advice about what is the best solution for your specific infrastructure and enterprise."
"The licensing fees for this solution are approximately $3,000 USD per year."
"We are using the free version of this solution."
"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 XI is open source."
"Nagios Core does not have any payment, but Nagios XI requires payment for the license."
"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."
"For our country in North Africa, it's expensive and we could purchase another solution for that price. But it's a reasonable price if we're speaking in international terms."
"The cost of the license and support are separate. If you want platinum call support, it will cost more than a regular call. I did not opt for it, as it is an additional cost."
"OP5 has a very low price as a solution, compared to many other solutions out there."
"It was not expensive. And because it's less demanding in terms of hardware, you don't have to pay for another SQL or other database license, and you can have a huge installation on one machine..."
