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.

A highly stable solution that can be used to monitor system availability
The most valuable feature of Opsview is the ability to clone the services when you're monitoring something out of the test setup. You can clone that service, and it allows you to add new services quickly. You can bring up new servers, and you can easily add them. Also, there's an API to be able to add services as well. We don't use the API. We mostly use the cloning function because it stores everything in a back-end database. The underlying monitoring platform for our version is Nagios. That's where we upgraded from Nagios to Opsview.

Enables seamless global client monitoring with reliable remote connectivity
I use the solution to provide a perfect environment for remote connectivity with my clients. Many tools that I require for system maintenance are included. I can easily monitor all of my clients throughout the world I did not give much thought to it, however, improvements could be made to Zabbix.…

Quotes from Members

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

Pros

"The most valuable feature of Nagios XI is customization. We can customize based on our requirements. We can do modifications and implement a lot of scripts. Additionally, it is easy to use."
"It is an open-source platform with valuable features for performance and stability."
"The most valuable features of Nagios XI are you can customize it based on your use case and requirements. It is flexible and easy to integrate with our systems. You can customize the solution by adding additional features using code."
"Though I downplayed the administrative NCC GUI, this is by far the strongest aspect of the Nagios XI product."
"Nagios is stable and it's easy to use the monitoring software, which is why we chose this product."
"Nagios XI is a simple monitoring tool with performance management."
"The alerting system is very effective."
"I can monitor a software made in-house to software of bigger companies."
"It's a good solution. It covers all aspects of monitoring purposes."
"I am satisfied with the overall product since it works well…It is a stable solution."
"What was very compelling about OpsView was that we could dial out the noise and have meaningful and actionable alerts."
"We use this solution for internal monitoring our own cloud platform because we are a public cloud provider. We also use it for monitoring purposes on behalf of our clients."
"The most valuable feature of Opsview is the ability to clone the services when you're monitoring something out of the test setup."
"The most valuable function for me is the auto-discovery of interfaces in devices. When you integrate devices into the tool, it automatically finds the interfaces, which is very helpful for my job. Integration and configuration run smoothly in my experience with Juniper and Aruba devices."
"It not only provides the preconfigured item monitoring feature, but it is also easy to configure custom items."
"Dashboard and the customization of the items and triggers are the most valuable features."
"The most valuable features of Zabbix are flexibility and a single interface for different types of monitoring."
"The most valuable feature is that it provides network segregation for server monitoring."
"Zabbix is a cost-effective solution. We're a small organization with a few dozen devices to monitor, and it was available for free. We can see what we need. We haven't done an in-depth analysis on it, but we're currently okay with the product."
"The product is very stable."
"The basic setup is very easy."
 

Cons

"The user interface needs improvement. Many tools have poor user interfaces, making them hard to manage and navigate."
"The reporting structure could be more streamlined."
"It is really difficult to integrate Nagios XI with another system to generate logs and alert our management of failures in security infrastructure."
"The product does not have SAP monitoring."
"Improve the documentation, examples, and best practices, therefore users can understand how to do things."
"I would like to see support for notification via SMS."
"We often need to develop custom plugins to get Nagios to work the way we want it to work because the features we need are not always available in Nagios."
"The product uses the backend as Perl and could be modified to a more lightweight solution like what's being offered by other vendors."
"Customized reporting can be improved."
"In a future release, we would like to have Observ for AI. Any AI and intelligence it can add to the monitoring is obviously beneficial. We would also like to have automated callouts."
"Maybe the graphical representation can be improved. It can be enhanced for better visualization. It could be a little better. And the graph center can be improved."
"Some of the graphics on Opsview could be improved."
"Pricing and a few certain aspects in the solution needs to be improved."
"In the next release, I'm hoping for features targeted towards larger users with more customizable options. Despite this, I think pre-canned reports that can be used straight out of the box would be beneficial rather than having to configure each report individually. Additionally, a deeper dive into software configurations on the machines would be useful, although I understand there may be challenges in implementing this due to scripting requirements. More documentation would also be appreciated."
"The dashboard and the graph section could be a little bit more professional."
"Outside of the normal standard monitoring, I would like to extend patching, importing patching, and supporting patching for Windows Servers."
"Zabbix technical support is sold separately."
"Its UI should be improved. They did some improvements in version 5, but it could benefit from some more work. Its integrations should also be improved. They've been active for one year, and they seem to have noticed that. It has new integrations, but it could benefit from more integrations. As far as I know, there is no model to push statistics, metrics, or events towards Zabbix. This type of API isn't yet there, whereas some other tools provide an API for this."
"The product could be more secure and more stable."
"The solution needs to add features for finding loopholes or problems and their root causes."
"Look and feel."
 

Pricing and Cost Advice

"Licensing costs are reasonable."
"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."
"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."
"The pricing is really cost efficient. The licensing is perpetual and can be renewed very easily."
"Nagios XI is an expensive solution."
"You can grow into the higher-priced scale as they learn how to utilize the features for Nagios XI."
"Nagios Core does not have any payment, but Nagios XI requires payment for the license."
"I would rate pricing a seven out of ten, where ten is the highest price."
"The solution is not cheap. I think that the pricing is a little bit on the high side."
"The solution is priced similarly to other tools offering similar features."
"The tool's licensing is good."
"The solution is open source so is free."
"We’re using the free version, which covers all our current needs."
"Zabbix is an open-source tool, and it's free to use."
"There is no license but we need to pay for support."
"Zabbix is open-source so if one wishes to implement it in-house, they must have qualified professionals to set up and optimize databases, Linux/Unix OS, PHP, Apache, and depending on what is monitored, a full-stack network and systems administrator may be needed."
"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."
"The solution is free to use but they offer support as a paid service. If you can go read the manuals and do the fine-tuning based on your needs, you do not need to pay anything and you will have a full solution."
