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

"It's an essential part of our infrastructure, and we'll keep using it."
"The product allows comprehensive monitoring of your environment, from basic monitoring of your servers health to more complex tasks like AD, database, and, to some extent, application-level monitoring."
"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."
"Nagios XI allows my customer to monitor literally thousands of network and computing endpoints (both hardware and software) in real time, including custom derived SNMP polling and traps."
"Since the cost is zero and it can use a fairly cheap server to run on the ROI is nearly immediate."
"Nagios is stable and it's easy to use the monitoring software, which is why we chose this product."
"I really found Nagios a perfect fit for us and a good product to work with."
"Nagios XI is easy to install, which sets it apart from other open-source solutions I've tried."
"It is a stable solution...It is a scalable solution."
"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."
"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."
"Visibility is a valuable feature, the ability to see even if the traffic is not going into the firewall"
"The most valuable feature is the log, which can be analyzed by our SIEM solution."
"Compared to many other products in the market, I think LogRhythm has the highest cost to performance ratio in terms of its value."
"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 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."
 

Cons

"Nagios XI can improve its GUI for users with a new look."
"The NCC does have issues where it locks up or an admin cannot be sure if the system configuration was exact."
"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."
"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."
"We'd like to see more integration capabilities."
"The user interface needs improvement."
"Backup mechanisms and some kind of templating system for dashboards are needed."
"Our customers would always like to see additional features."
"Sometimes it's hard to find the network devices' self-audit logs."
"I would like to see better integration with multiple products. Integration is not something that is readily available for most of the products."
"Their technical support isn't so great."
"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 training for this product is not very good and needs to be improved."
"LogRhythm NetMon's pricing model is an area of concern that should be made a little bit cheaper in comparison to the other players in the market currently."
"One thing that surprised me was the current version of LogRhythm does not natively support Windows 2016."
 

Pricing and Cost Advice

"Nagios XI is open source."
"It is good to contact experts for advice about what is the best solution for your specific infrastructure and enterprise."
"We are using the free version of this solution."
"Nagios XI is an expensive solution."
"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 pricing is high with separate licensing for the product and support."
"You can grow into the higher-priced scale as they learn how to utilize the features for Nagios XI."
"The licensing fees for this solution are approximately $3,000 USD per year."
"The product is expensive for smaller companies."
"The price of this solution is too high, so it should be made more practical and more valuable for the customer."
"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."
"NetMon's licensing costs about $85k per year, with some extra costs for support."
"LogRhythm's licensing part is something that depends on the license you want since they offer it on a perpetual and subscription basis."

Nagios vs. Zabbix vs. PRTG vs. Spiceworks vs. Solarwinds Network Performance Monitor
