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.

Has supported real-time event detection and reporting accuracy while database integration has required extra effort
Sometimes it may be difficult to incorporate new additional databases in NetMon, and we faced some challenges at that time. However, currently, it is not giving many challenges.It is difficult to integrate NetMon with other databases. We can customize NetMon's monitoring views, but it is done by the team who handles it, as it is outsourced.

Quotes from Members

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

Pros

"Nagios XI helps us monitor the bandwidth of the internet connection, HTTP, DNS, active directory services, and exchange data availability. We have multiple servers to monitor databases, availability of servers, and ping."
"In my view this product is very good value for money when compared with other commercially provided monitoring solutions."
"They have very accurate and fast support."
"Nagios XI is easy to install, which sets it apart from other open-source solutions I've tried."
"The features I've found the most useful are the plug-ins, the fact that you can connect almost everything to it."
"You want to monitor a specific metric that nobody else has? You can do it even with the most basic of scripting skills, and you can always share it with the vast community of Nagios Exchange."
"The dashboard allows you to see what's going on in the overall system."
"If you are a mid-sied company with an eye on expansion, this solution is very good."
"In general, this is a good product."
"The analytics feature is the most valuable feature."
"Compared to many other products in the market, I think LogRhythm has the highest cost to performance ratio in terms of its value."
"We are using NetMon's real-time traffic analysis regularly with a team of four members who effectively monitor all alerts and events, which has helped them identify whether there could be a severe incident."
"NetMon's best feature is traffic analysis."
"The most valuable feature is the log, which can be analyzed by our SIEM solution."
"Visibility is a valuable feature, the ability to see even if the traffic is not going into the firewall"
"The initial setup is straightforward because we can deploy an open server."
 

Cons

"The reporting structure could be more streamlined."
"The interface could be more user-friendly."
"I feel that the maturity and user interface needs to be improved."
"I would like a much easier GUI so that I can delete events and logs, which will free up a lot of space."
"Reporting items needs more improvement and need to be more flexible based on customer needs."
"The product uses the backend as Perl and could be modified to a more lightweight solution like what's being offered by other vendors."
"Nagios provides most of the features by default, however to add more services to it, it requires additional plugins which require little effort on administrative end."
"It is really difficult to integrate Nagios XI with another system to generate logs and alert our management of failures in security infrastructure."
"Some of the automated tasks we can perform on QRadar cannot be performed on LogRhythm because the solution has limitations."
"I would like to see better integration with multiple products. Integration is not something that is readily available for most of the products."
"The training for this product is not very good and needs to be improved."
"The main concern is that LogRhythm has not improved NetMon but instead introduced a separate product, which many customers, including us, would prefer to be integrated into a single platform for easier management."
"Sometimes it may be difficult to incorporate new additional databases in NetMon, and we faced some challenges at that time."
"Their technical support isn't so great."
"There is an issue with tunneling in relation to how the connectivity is established between the end devices and where NetMon is installed. On the console, I often observe that there's a difference of a few seconds or maybe a minute, and this lag time should not be there."
"The platform's integration features often need to be improved."
 

Pricing and Cost Advice

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

"I don't have visibility into the pricing of LogRhythm NetMon as it's handled through our commercial partnerships."
