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.

Monitoring solution provides comprehensive visibility across IT infrastructure
The good thing about Nagios Core is it covers everything. Everything in the IT domain, you can monitor anything. You can even monitor printers, the ports of printers, Core workstations, and storage. You can monitor the workflow Core and the utilization of computes. If you want to grasp everything of your IT equipment on a single interface, you can use Nagios. It's the best one. It provides dashboards, and you can also configure your emails and alerts with it. If something is critical, you can configure it to notify via emails. It has a very handy dashboard, providing live alerts and visibility for everything.

Quotes from Members

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

Pros

"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."
"Overall, I would recommend FortiMonitor to others."
"FortiMonitor is really easy to use for monitoring the logs on FortiGate...It is a stable product."
"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."
"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."
"The product's initial setup phase is easy."
"FortiMonitor offers comprehensive monitoring capabilities, allowing me to track network traffic in and out effectively."
"FortiMonitor's dashboard is very informative and user-friendly."
"I like that it's very simple to install, easy to manage and deploy, and easy to use for monitoring."
"This is probably the greatest advantage of Nagios - it can be customized to a degree to suit your monitoring needs."
"Monitoring with Nagios Core is helpful because it provides immediate alerts if something goes down, such as a server, or wireless router, or if there's a cable break. This allows us to respond promptly to any issues."
"Nagios Core is a great tool for monitoring the infrastructure including MSM queues, and when we use the agent, we can add other things as well."
"Dashboard provides monitor of total assets."
"We have the ability right now to see and create reports to tell whether or not we're meeting our SLAs on our production servers, through it."
"Nagios is able to minimize server downtime and this in turn helps to generate more revenue."
"Nagios Core is very configurable. Whatever you want, you can do it."
 

Cons

"FortiMonitor's monitoring could be much better. It should be like, in Palo Alto."
"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 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."
"There are areas for improvement that FortiManager is addressing."
"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."
"Sometimes, during high CPU usage, we cannot access FortiMonitor and must refresh it."
"FortiMonitor could be improved by making it more convenient for smaller workloads, such as when configuring a few branches."
"Nagios' great customizability is also one of its greatest drawback."
"This solution is not scalable at all. If you want to add an AI, or if you wanted to monitor different types of metrics, you won't get the most out of it."
"It's not that easy to install the product itself. Also, the UI is a bit hard for regular users to navigate through."
"Nagios Core is limited in terms of distributed setups, and there is no central view for remote data centers."
"The NetEase reporting structure needs improvement, especially the availability report, which is weak."
"I like to have the option to configure Nagios using the web interface."
"Bandwidth monitoring is the pain point for me because Nagios Core does not monitor bandwidth effectively like Cacti does."
"Nagios Core can improve the graphical interface, it would make things a little easier."
 

Pricing and Cost Advice

"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."
"Compared to other solutions, FortiMonitor is a very expensive solution."
"There are additional costs needed for certain functionality, such as scalability."
"The price of FortiMonitor is approximately $200 annually for 225 users. The price is competitive."
"FortiMonitor's price is very high."
"We have a large customer base for Fortinet, and the additional buying power got us really great discounts."
"The tool's pricing model in Vietnam is a bit high. I rate the product price as an eight out of ten."
"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."
"Nagios Core is free to use."
"Most the plugin features are free."
"We have saved a lot of time, money, and effort in reducing disaster times, which is owed to Nagios quick alerting."
"It's free."
"The Nagios Core (PNP4Nagios + Core) is free and can be setup by Netadmin within a few hours. The only additional cost is the cloud server."
"The enterprise version has technical support. The version we are using is free."
"The product is cheaply priced."
"Lessening the price point would be an improvement."
