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 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."
"All of them, but mainly: Highly-efficient server performance monitoring engine Configuration wizards Infrastructure management Configuration snapshot."
"The most valuable feature is the dashboard, where I can have a single screen that provides a summary for hundreds of servers."
"It is a very stable solution and the best solution for monitoring any IT infrastructure for all companies."
"It's a monitoring agent. It's designed to do one thing. Its most valuable feature is its monitoring."
"Nagios XI helped me to draw the network and check for system failures."
"Nagios is the best monitoring tool that I have ever worked on."
"The solution is pretty stable."
"NetMon's best feature is traffic analysis."
"The initial setup is straightforward because we can deploy an open server."
"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."
"It is a stable solution...It is a scalable solution."
"Visibility is a valuable feature, the ability to see even if the traffic is not going into the firewall"
"It has a very strong artificial intelligence engine."
"The analytics feature is the most valuable feature."
"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

"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."
"This solution would be improved with the inclusion of additional services. Monitoring streaming services is an example of something that is not currently supported, so in order to handle this, I would have to write a script."
"The user interface needs improvement. Many tools have poor user interfaces, making them hard to manage and navigate."
"Adding new servers and passive checks (which require setting up agents and NRDS) on servers are a little difficult to do properly when employees don't understand the process."
"If you are monitoring network devices, often it's not scaled for large corporations. Definitely, a minus in that area."
"I would like to see support for notification via SMS."
"Improve the documentation, examples, and best practices, therefore users can understand how to do things."
"Nagios XI doesn't provide scripting. For example, if we have built up multiple IPX tunnels from a base location to a data center location and want to monitor or trigger an alert if the tunnel goes down, Nagios XI does not automatically send alerts notifying us that the tunnel is down."
"Could use a topology diagram which would help get an exact visual."
"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."
"One thing that surprised me was the current version of LogRhythm does not natively support Windows 2016."
"The platform's integration features often need to be improved."
"Their technical support isn't so great."
"Sometimes it's hard to find the network devices' self-audit logs."
"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

"Licensing costs are reasonable."
"Nagios Core does not have any payment, but Nagios XI requires payment for the license."
"The pricing is really cost efficient. The licensing is perpetual and can be renewed very easily."
"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."
"It is good to contact experts for advice about what is the best solution for your specific infrastructure and enterprise."
"Nagios XI is an expensive solution."
"You can grow into the higher-priced scale as they learn how to utilize the features for Nagios XI."
"The product is expensive for smaller companies."
"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."
"The price of this solution is too high, so it should be made more practical and more valuable for the customer."
"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
I have researched a quite a few network monitoring tools which can be used for various monitoring purposes of not only the servers, but the intermediate routers as well. There are majorly three types of these softwares. Ones which are completely open-source, you can do almost anything you want…
