Managing diverse networks with detailed alerts enhances device oversight
FortiManager is very helpful in managing our networks. We use it to manage 20 farms and various networks with hundreds of devices. The version we are using provides more detail than the older dashboard. We appreciate the alerting capabilities, which are integrated with SolarWinds to notify our team via SMS.

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.

Quotes from Members

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

Pros

"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 has a very intuitive dashboard, which makes it particularly helpful for analyzing traffic, alerts, and other information."
"With FortiMonitor, you can get all the logs of the traffic information of the destination or the source."
"FortiMonitor's dashboard is very informative and user-friendly."
"The most valuable feature of this solution is what the devices are used for. We have big backups for our Cradlepoint solutions, but FortiMonitor is a great routing device and we love working with them."
"FortiMonitor is 100% stable."
"The product's initial setup phase is easy."
"FortiMonitor has a very intuitive dashboard, which makes it particularly helpful for analyzing traffic, alerts, and other information."
"The most valuable feature is the monitoring of processes."
"Since the cost is zero and it can use a fairly cheap server to run on the ROI is nearly immediate."
"The solution is pretty stable."
"The integration with the alerting software, automated maintenance windows, and the ability to set up templates and groups of checks, as well as customize the checks themselves, are very valuable features."
"Nagios XI helped me to draw the network and check for system failures."
"It has a lot of flexibility for customization and a wide range of metrics."
"The most valuable features of Nagios XI are you can customize it based on your use case and requirements. It is flexible and easy to integrate with our systems. You can customize the solution by adding additional features using code."
"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."
 

Cons

". Enhancements in the dashboard, such as clearer alerting, maintenance window management, software version tracking, and better visualization, would be beneficial."
"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."
"FortiMonitor could improve by having compatibility with other operating systems, such as Linux."
"The tool's price in Vietnam is high, making it an area of concern where improvements can be made."
"Additionally, there are no AI features in FortiMonitor, which might be an area for enhancement."
"Sometimes, during high CPU usage, we cannot access FortiMonitor and must refresh it."
"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."
"Its simple deployment but complexity comes once you have to import more plugins."
"They need to develop a better integration with a common ticketing system will be great."
"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 reporting part should be made simpler. While we can obtain all the reports we need, we always have to create work-arounds to get them."
"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 installation can get very difficult depending on what Linux flavour you are using."
"Backup mechanisms and some kind of templating system for dashboards are needed."
"Nagios XI can improve its GUI for users with a new look."
 

Pricing and Cost Advice

"There are additional costs needed for certain functionality, such as scalability."
"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."
"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 tool's pricing model in Vietnam is a bit high. I rate the product price as an eight out of ten."
"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."
"FortiMonitor's price is very high."
"The price of FortiMonitor is approximately $200 annually for 225 users. The price is competitive."
"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."
"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."
"Nagios XI is open source."
"The pricing is really cost efficient. The licensing is perpetual and can be renewed very easily."
"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."
"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."

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