Great for identifying application interdependencies with helpful support but needs better visualizations
We're just trying to identify the application interdependencies, which normally reside on different servers, including web servers, database servers, enterprise service bus, et cetera, up to your presentation layer before we start moving stuff around. Normally, the reason why we use these tools is to understand what assets we have, where they're deployed, and how they enter and operate before we decide to go move something from point A to point B. The solution is going to allow me to establish a wave or migration plan where you have different waves of migration and then you actually have move groups to try and get your application moved from A to B seamlessly. A to B could be on-premise to on-premise. It could be on-premise to cloud. Et cetera. The solution can tell me what components can I deploy, for example, into a cloud space, without having to refactor my applications since that can be quite time-consuming and costly.

Simplifies setup and requires user interface enhancement
Nagios XI is easy to install, which sets it apart from other open-source solutions I've tried. Typically, setting up a monitoring system on Linux involves cloning files from GitHub, building it, and installing many dependencies, but with Nagios XI, it wasn't like that. Nagios XI simplifies our setup and reduces the time spent configuring monitoring tools.

Quotes from Members

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

Pros

"This is a must-try product."
"You cannot hide from the wire; all truth lives in the packets, and ExtraHop gets them to talk!"
"This solution is more applications reference architecture focused. Its benefit is that it specializes in that space."
"Not only can you look at the protocol import level. It also has a live PCAP analysis."
"ExtraHop is far ahead of anything comparable in the industry."
"ExtraHop came out with the best price, and I think that it gives us a broader view of our network."
"ExtraHop is far ahead of anything comparable in the industry."
"It gives you full 360-degree visibility into your entire infrastructure."
"Our infrastructure is now under monitoring proactively and we don't have to wait for complaints from the customers or internal operation team to inform regarding any issue with the service."
"BPI: It allows defining peripherals to map business criticality for efficient monitoring, as required."
"Nagios XI is easy to install, which sets it apart from other open-source solutions I've tried."
"It has a wide variety of plugins in existence, but when there's no plugin available it is quite simple to integrate one's own programs and scripts."
"I really found Nagios a perfect fit for us and a good product to work with."
"Nagios is an open source monitoring tool for monitoring network services, with easy installation, a user-friendly and configurable interface, and the ability to monitor disk space, CPU utilization, memory usage, host availability, NFS availability and many other things, making it widely used in IT markets."
"The integration with the alerting software, automated maintenance windows, and the ability to set up templates and groups of checks, as well as customize the checks themselves, are very valuable features."
"In my experience with Nagios, I've found that the most valuable features are the scalability and extensibility through using scripts."
 

Cons

"This solution would be improved if it had the ability to retain data longer."
"We'd like to see a local presence within the region in order to have seamless service whether it's the support, the implementation, or professional services."
"There is room for improvement in the security part. They have a new solution, ExtraHop Reveal(x), and I think it needs improvement."
"Network visibility is something that needs to be improved."
"The solution could get more aggressive in the discounting of the overall cost."

"I would improve the Rule-Based Access Control (RBAC) by providing granular access control to the data."
"They need more documentation for the plugins."
"For some, it may be difficult to deploy."
"The technical support is variable - sometimes I get answers, but most of my tickets go unanswered."
"The pricing has recently risen. I know they've changed what is covered under the license, however, it doesn't change the way we use it and adds nothing to our experience, and yet we now have to pay more."
"I would like to be able to extend it to all of our data centers, whether they are in the cloud or not. It would be helpful if I could connect everywhere."
"The scalability of Nagios XI is scalable. However, it is not easy to do."
"The GUI could be improved. It's a bit too basic, and maybe having a GraphQL interface would resolve this."
"From an alerting point of view, some graphics and metrics don't work properly with Nagios XI as they do with Checkmk."
 

Pricing and Cost Advice

"The pricing is fair considering the value provided."

"Nagios Core does not have any payment, but Nagios XI requires payment for the license."

"Nagios XI is open source."

"As it is not an agentless tool, I think it is expensive."
