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

"I would recommend this solution because it's so powerful with no limitation, especially when using the XI version."
"It's great for monitoring IT services infrastructure."
"I really found Nagios a perfect fit for us and a good product to work with."
"It's very easy to install it and manage it with Nagios XI's interface."
"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."
"Nagios is a custom API manager, and we can expose custom APIs for our integration. This is a great feature."
"Nagios is the best monitoring tool that I have ever worked on."
"BPI: It allows defining peripherals to map business criticality for efficient monitoring, as required."
"It has a very strong artificial intelligence engine."
"NetMon's best feature is traffic analysis."
"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."
"Compared to many other products in the market, I think LogRhythm has the highest cost to performance ratio in terms of its value."
"The protocols with which you see the traffic for a particular website that a client has in their environment, for example, are valuable. We can monitor whether the traffic is up to the mark or whether they need to add more bandwidth. Also, we can see if we're able to get real-time environment data as well. The customization dashboard is really good. LogRhythm NetMon has its own in-built dashboards which are helpful in guiding customization."
"Visibility is a valuable feature, the ability to see even if the traffic is not going into the firewall"
"It is a stable solution...It is a scalable solution."
"The most valuable feature is the log, which can be analyzed by our SIEM solution."
 

Cons

"There's room for improvement in the visibility, and in the ability to extract information. Stuff like this should be more simple."
"The GUI could be improved."
"The PNP4Nagios plugin not working easily with XI is an issue for me, because some open source monitoring plugins do not work out of the box. But in the end, you learn to live with it."
"The NCC does have issues where it locks up or an admin cannot be sure if the system configuration was exact."
"I think that the community needs to concentrate development to get a standard GUI (Adagios is a side project) and gives the user a better notification system."
"The reporting structure could be more streamlined."
"They need to develop a better integration with a common ticketing system will be great."
"The way Nagios displays information isn't easy for a new user to understand. It's not intuitive enough. You need to read some tutorials or be trained to understand what it's displaying. Also, I think it needs more features to improve network visibility because there are some things you can't detect."
"Their technical support isn't so great."
"Sometimes it may be difficult to incorporate new additional databases in NetMon, and we faced some challenges at that time."
"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."
"Our customers would always like to see additional features."
"I would like to see better integration with multiple products. Integration is not something that is readily available for most of the products."
"The platform's integration features often need to be improved."
"Sometimes it's hard to find the network devices' self-audit logs."
"One thing that surprised me was the current version of LogRhythm does not natively support Windows 2016."
 

Pricing and Cost Advice

"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."
"We are using the free version of this solution."
"Nagios Core does not have any payment, but Nagios XI requires payment for the license."
"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."
"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."
"It is good to contact experts for advice about what is the best solution for your specific infrastructure and enterprise."
"As it is not an agentless tool, I think it is expensive."
"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."
"LogRhythm's licensing part is something that depends on the license you want since they offer it on a perpetual and subscription basis."
