Monitoring capabilities keep operations running smoothly and alerts enhance proactive system management

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

"Overall, I would recommend FortiMonitor to others."

"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."

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

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

"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."

"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."

"The product's initial setup phase is easy."

More FortiMonitor pros

"The most valuable feature depends on the project. It's great if you need to check to ensure a service is running 24/7. I can use the full solution for free, and it's flexible. If I need to add a dashboard, I can integrate it with Nagios. Cloud synchronization is wonderful."

"I would rate the overall solution ten points out of ten."

"We use the product to monitor server applications."

"Provides timely notifications."

"Nagios Core is stable."

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

More Nagios Core pros

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."

"FortiMonitor's monitoring could be much better. It should be like, in Palo Alto."

". Enhancements in the dashboard, such as clearer alerting, maintenance window management, software version tracking, and better visualization, would be beneficial."

"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."

"FortiMonitor needs to improve its alert system."

"FortiMonitor could improve by having compatibility with other operating systems, such as Linux."

"Sometimes, during high CPU usage, we cannot access FortiMonitor and must refresh it."

More FortiMonitor cons

"I believe Nagios Core will need to provide an option for big data platforms in the future."

"The dashboard should be improved."

"Nagios Core can improve the graphical interface, it would make things a little easier."

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

"The UI is a little outdated and graphics could be displayed in a better way."

"There is room for improvement in the graphics."

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

"The initial setup process could be easier."

More Nagios Core cons

Pricing and Cost Advice

"FortiMonitor's price is very high."

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

"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."

"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."

"There are additional costs needed for certain functionality, such as scalability."

"Lessening the price point would be an improvement."

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

"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."

"It's free."

"The solution is expensive."

"We are using the free version."

"It's free."

"Most the plugin features are free."
