Monitoring capabilities keep operations running smoothly and alerts enhance proactive system management
We use FortiMonitor to monitor the infrastructure of our customers. We check on what is happening with their operations, monitor bandwidth, ensure configurations are appropriate for the customer, and identify if anything is going wrong The most valuable features of FortiMonitor are its redundancy…

Effective alerting enhances network monitoring experience with an easy setup
We love Nagios XI due to the fact that JPS Web is very useful. JPS monitors the modem and performs switching, monitoring the computer, and performing switching. We implement some applications and traffic monitoring. The alerting system is very effective. For instance, if we have an alarm on some RAM storage if the traffic is cut or dropped.

Quotes from Members

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

Pros

"With FortiMonitor, you can get all the logs of the traffic information of the destination or the source."
"It provides the best firewall features."
"FortiMonitor offers comprehensive monitoring capabilities, allowing me to track network traffic in and out effectively."
"FortiMonitor has a very intuitive dashboard, which makes it particularly helpful for analyzing traffic, alerts, and other information."
"The tool continuously improves, adapting to support new vendors and technologies. Importantly, it automates the process, triggering alerts when devices require attention, and eliminating the need for manual intervention."
"FortiMonitor is 100% stable."
"The most valuable feature of FortiMonitor is the overall ability to monitor the health of the environment."
"In FortiMonitor, we're linked up with our Netgear, CactusServer, and NOC. It's really valuable because everything's migrating to one dashboard for us system engineers. We can keep an eye on traffic, blocked sites, and the health of our hardware. That last part, about knowing if something's going to fail soon, is super important. It gives us time to sort things out before any big problems happen. As a system engineer, I need to keep tabs on everything – temperature, monitoring systems, and network operations. This data is really handy because it helps me ensure our site runs smoothly, whether it's turning systems on or off. Just last night, there was a system failure, but thanks to real-time monitoring, I quickly identified the problem and got the necessary replacement parts."
"Nagios XI helped me to draw the network and check for system failures."
"I can monitor a phone on a desk to very big servers of any company."
"Nagios XI is a simple monitoring tool with performance management."
"Nagios XI simplifies our setup and reduces the time spent configuring monitoring tools."
"I can monitor a software made in-house to software of bigger companies."
"It's great for monitoring IT services infrastructure."
"The installation is no problem. I've installed Nagios several times."
"The most valuable feature is the dashboard, where I can have a single screen that provides a summary for hundreds of servers."
 

Cons

"There is room for improvement in the FortiMonitor report. It is not ideal for showcasing to tech customers or managers, especially when trying to display high CPU usage from logins within a specific range of months or the most recent month."
"The solution's initial setup process is time-consuming."
"The tool's price in Vietnam is high, making it an area of concern where improvements can be made."
"FortiMonitor could improve by having compatibility with other operating systems, such as Linux."
"FortiMonitor needs to improve its alert system."
"I think the current features are really good for me, nothing else comes to mind right now. Maybe some small improvements could be made in the customization and configuration part of the UI to make it easier or more intuitive. Customizable UI options, like we saw in the demo, could be helpful for everyone. But in our operational environment, having clear health status and system details is crucial for us system engineers. One feature I'd really like to see is a credential management system. It would help us keep track of who's logged in and how many times, which is important due to user restrictions. Sometimes, we need to manage logins more efficiently, like logging off other users to free up credentials. So having a feature like that would be really helpful."
"FortiMonitor could be improved by making it more convenient for smaller workloads, such as when configuring a few branches."
". Enhancements in the dashboard, such as clearer alerting, maintenance window management, software version tracking, and better visualization, would be beneficial."
"I would like to see more customization in the network map because it is a bit tricky to use it."
"We often need to develop custom plugins to get Nagios to work the way we want it to work because the features we need are not always available in Nagios."
"The installation and monitoring need improvement."
"It can be quite difficult to know which drivers and agents to use when setting up."
"The technical support is variable - sometimes I get answers, but most of my tickets go unanswered."
"We'd like to see more integration capabilities."
"The user interface needs improvement. Many tools have poor user interfaces, making them hard to manage and navigate."
"I would like to see support for notification via SMS."
 

Pricing and Cost Advice

"FortiMonitor's price is very high."
"On a scale from one to ten, I rate the pricing a nine since it is a good solution that is available at a cheap price."
"The tool's pricing model in Vietnam is a bit high. I rate the product price as an eight out of ten."
"The price of FortiMonitor is approximately $200 annually for 225 users. The price is competitive."
"We have a large customer base for Fortinet, and the additional buying power got us really great discounts."
"Compared to other solutions, FortiMonitor is a very expensive solution."
"There are additional costs needed for certain functionality, such as scalability."
"In terms of licensing, while it may not be the most expensive option on the market, it's relatively cost-effective. You can obtain licenses at a lower cost, with the calculation being straightforward. For example, if you onboard around 5,000 devices, you'll need approximately 5,000 licenses, as each device typically counts as one license."
"Licensing costs are reasonable."
"You can grow into the higher-priced scale as they learn how to utilize the features for Nagios XI."
"The pricing is high with separate licensing for the product and support."
"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."
"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."
"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."
"The pricing is really cost efficient. The licensing is perpetual and can be renewed very easily."
