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…

Valuable reporting and alert system with room for PDF export improvements

The NetEase reporting structure needs improvement, especially the availability report, which is weak. It should be generated automatically with minimal human intervention and should be exportable as a PDF. Besides that, an integrated PDF export feature for reports is necessary. Also, the alert mechanism and graphing mechanism need to be integrated properly into Nagios Core. Currently, integrating these requires advanced Linux knowledge. Integration of more visualization tools like Grafana and Prometheus for better graphing and visualization is also recommended.

Quotes from Members

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

Pros

"It provides the best firewall features."

"FortiMonitor is really easy to use for monitoring the logs on FortiGate...It is a stable product."

"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 offers comprehensive monitoring capabilities, allowing me to track network traffic in and out effectively."

"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 product's initial setup phase is easy."

"With FortiMonitor, you can get all the logs of the traffic information of the destination or the source."

"FortiMonitor has a very intuitive dashboard, which makes it particularly helpful for analyzing traffic, alerts, and other information."

More FortiMonitor pros

"The reporting structure and the feature set are valuable to me."

"We use the product to monitor server applications."

"The most valuable features are the reports and the way it generates the report in a graphical manner."

"Nagios Core is very configurable. Whatever you want, you can do it."

"Nagios Core integrates with tools like Splunk, Datadog, or Dynatrace. It is usually used as a feed to provide more technical information about devices or hosts to another system."

"Alert calls occur anytime a service goes down or a matrix is difficult and that helps us to quickly restore service and transfer work."

"The most valuable feature is the performance parameters of the system."

"I like the way the solution sends alerts and how it keeps on escalating them."

Cons

"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 needs to improve its alert system."

"FortiMonitor could be improved by making it more convenient for smaller workloads, such as when configuring a few branches."

"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."

"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."

More FortiMonitor cons

"The initial setup process could be easier."

"Would benefit from aggregations if a particular server goes down."

"The interface could be improved."

"Making it a little easier to configure and set up from the start would help. There are multiple layers that you have to wade through to be able to set it up, to do it the right way, and to get it to do what you want it to do."

"Nagios Core is limited in terms of distributed setups, and there is no central view for remote data centers."

"Bandwidth monitoring is the pain point for me because Nagios Core does not monitor bandwidth effectively like Cacti does."

"The UI is a little outdated and graphics could be displayed in a better way."

"The NetEase reporting structure needs improvement, especially the availability report, which is weak."

More Nagios Core cons

Pricing and Cost Advice

"We have a large customer base for Fortinet, and the additional buying power got us really great discounts."

"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."

"Compared to other solutions, FortiMonitor is a very expensive solution."

"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."

"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 price of FortiMonitor is approximately $200 annually for 225 users. The price is competitive."

"We are using the free version."

"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."

"Nagios Core is free to use."

"We are using the open-source, unpaid version."

"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."

"I would rate the solution's pricing an eight out of ten."

"We are using the free version of Nagios Core."
