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

"FortiMonitor has a very intuitive dashboard, which makes it particularly helpful for analyzing traffic, alerts, and other information."
"FortiMonitor is 100% stable."
"The solution helps to see client infrastructure. It has many boxes and blinks green or red when the station goes up or down. We have different domains for the device groups that we monitor."
"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."
"FortiMonitor offers comprehensive monitoring capabilities, allowing me to track network traffic in and out effectively."
"The most valuable feature of FortiMonitor is user monitoring. We are able to see if the user is following the policy or not from their system. Additionally, the solution integrates well with Fortinet FortiGate and has centralized management."
"FortiMonitor has a very intuitive dashboard, which makes it particularly helpful for analyzing traffic, alerts, and other information."
"FortiMonitor is really easy to use for monitoring the logs on FortiGate...It is a stable product."
"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."
"The dashboard allows you to see what's going on in the overall system."
"The technical support is good."
"The solution has a lot of plugins and scripts integrated with it."
"Since this is an open source technology, if we are capable of writing the plugins in any scripting language, this product allows us to monitor anything we want."
"An excellent solution that is easy and intuitive to implement."
"Nagios is stable and it's easy to use the monitoring software, which is why we chose this product."
"The most useful aspect of this solution is the ability to customize it for the client agent."
 

Cons

"We use FortiToken, and it's a pain to use because you have to send things through your phone and then confirm by email. Only after this can you log in. It's dual-factor authentication. I wish that I could just log in or bring up a dashboard where I could log in from."
"FortiMonitor could be improved by making it more convenient for smaller workloads, such as when configuring a few branches."
"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."
"The solution's initial setup process is time-consuming."
"Sometimes, we get corruption when upgrading from firmware to the new generation, causing a lot of issues."
"Sometimes, during high CPU usage, we cannot access FortiMonitor and must refresh it."
"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."
"I would like a much easier GUI so that I can delete events and logs, which will free up a lot of space."
"The Configuration Wizard needs improvement, because not all vendors are present."
"They need more documentation for the plugins."
"The user interface needs improvement. Many tools have poor user interfaces, making them hard to manage and navigate."
"The tool's AI model needs to be fixed."
"The user interface needs improvement."
"I would like to see more customization in the network map because it is a bit tricky to use it."
"From an alerting point of view, some graphics and metrics don't work properly with Nagios XI as they do with Checkmk."
 

Pricing and Cost Advice

"Compared to other solutions, FortiMonitor is a very expensive solution."
"We have a large customer base for Fortinet, and the additional buying power got us really great discounts."
"FortiMonitor's price is very high."
"The price of FortiMonitor is approximately $200 annually for 225 users. The price is competitive."
"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."
"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."
"The licensing fees for this solution are approximately $3,000 USD per year."
"We are using the free version of this solution."
"As it is not an agentless tool, I think it is expensive."
"The pricing is high with separate licensing for the product and support."
"Nagios Core does not have any payment, but Nagios XI requires payment for the license."
"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 an expensive solution."
"The pricing is really cost efficient. The licensing is perpetual and can be renewed very easily."
