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

"This is a very good solution and it is simple to use, for any company."
"For anyone who is interested in using this solution, I would recommend it."
"In my experience with Nagios, I've found that the most valuable features are the scalability and extensibility through using scripts."
"It's an essential part of our infrastructure, and we'll keep using it."
"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."
"If you are a mid-sied company with an eye on expansion, this solution is very good."
"I can monitor a software made in-house to software of bigger companies."
"I would recommend this solution because it's so powerful with no limitation, especially when using the XI version."
"NetMon's best feature is traffic analysis."
"But just having it there, it's incredibly smart, incredibly easy to use, and the breadth of information we get off it is really good for investigations for us."
"We were sold on the product based on the fairly narrow use cases that the sales reps gave us, and what we're seeing during our usage is that we can get there, and we're very excited about the potential."
"The analytics feature is the most valuable feature."
"In general, this is a good product."
"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."
"It is a stable solution...It is a scalable solution."
"LogRhythm NetMon's most impressive feature is that it's a bundled package, so you're not just relying on monthly data; you get a six-month view for more comprehensive indicators of compromise. This dual approach is precious. We implement LogRhythm NetMon in our cybersecurity strategy mainly for compliance and correlation of network, user, and decision activities, particularly for network firewalls and access control."
 

Cons

"The reporting structure could be more streamlined."
"Initially, we encountered problems during the setup as some errors were noted due to a few prerequisites not being fulfilled and having some configuration files to edit and plugins to add."
"Business services monitoring is still really basic."
"The user interface needs improvement. Many tools have poor user interfaces, making them hard to manage and navigate."
"It can be quite difficult to know which drivers and agents to use when setting up."
"The product could be optimized to improve the administrative user experience via the Nagios Core Configuration (NCC) GUI module."
"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."
"Sometimes it may be difficult to incorporate new additional databases in NetMon, and we faced some challenges at that time."
"The training for this product is not very good and needs to be improved."
"Previously, it was typically every Monday that I was coming in - it would die over the weekend - and I would spend a day cleaning up databases."
"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."
"I would like to see better integration with multiple products. Integration is not something that is readily available for most of the products."
"Our customers would always like to see additional features."
"Could use a topology diagram which would help get an exact visual."
"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."
 

Pricing and Cost Advice

"As it is not an agentless tool, I think it is expensive."
"Nagios Core does not have any payment, but Nagios XI requires payment for the license."
"You can grow into the higher-priced scale as they learn how to utilize the features for Nagios XI."
"The pricing is really cost efficient. The licensing is perpetual and can be renewed very easily."
"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."
"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."
"LogRhythm's licensing part is something that depends on the license you want since they offer it on a perpetual and subscription basis."
"Pricing is okay. There were some competitors that were extremely expensive and there were some which were really inexpensive but LogRhythm stayed in the middle of them."
"I don't have visibility into the pricing of LogRhythm NetMon as it's handled through our commercial partnerships."
"The price of this solution is too high, so it should be made more practical and more valuable for the customer."
"NetMon's licensing costs about $85k per year, with some extra costs for support."
"The product is expensive for smaller companies."
