    If anyone looking for the monitoring system for the infrastructure this is the go-to tool which monitors all infrastructure related components from server health to Networking and update us with mails and can be easily integrated with multiple other tools as needed for example PagerDuty , Also this suits good both on premises and cloud environments as well. If we are managing complex environment this tool for monitoring is best one.

    integrates seamlessly with Windows servers via WMI and PowerShell, providing deep insights into resource usage, performance metrics, and system health. It's excellent at tracking CPU, memory, disk space, and event logs, enabling rapid troubleshooting and proactive maintenance. PRTG Network Monitor also effectively monitors Fortigate devices, providing detailed data on firewall health, traffic patterns, bandwidth utilization, VPN status, and security alerts. This visibility helps detect and resolve network security issues promptly.

    Cons
    Nagios Enterprises
    • Robust, but visually old interface. Requires a lot of work to become presentable.
    • Small selection of dashlets to construct new views.
    • No MS Azure monitoring ability, nothing for “as service,” very limited Amazon cloud monitoring abilities.
    • Questionable price politics (could make it a lot less for developing markets to actually increase use of the product and R&D budgets).
    • No report designers nor the ability to create new reports. No changes in this area for years.
    • Overall lack of new developments, making this product more and more outdated.

    • Licensing on a per entity basis can be cumbersome for devices which have a ton of monitoring points like network switches\routers. Each sensor may count against a license, which could be a lot of you were monitoring every TX\RX of an SFP for example
    • A better method to easily template\copy monitors across devices
    • The navigation in the web GUI could be a little more straightforward in terms of the hierarchy

    I would renew it because the platform has brought us many technical and economic benefits that make the cost-benefit ratio very good. Additionally, to do so does not require large investments in training, licensing or infrastructure, and at the administration level, extensive knowledge is not required to be able to bear it.

    We
    are using Nagios XI in our organization primarily for monitoring all our
    application servers and databases, this is helping us in addressing all the
    infrastructure issues in advance by alerting us when it any server hits the
    threshold as per the initial parameter setup also it has free tier which helps for small scale applications monitoring to save some expenses.

    The tool is very intuitive to use and it is Windows-based (everybody knows how to use Windows) so it's easy to get into. Every time is setup in a hierarchy so if you have a good initial hierarchy design, it will really reduce administrative effort down the road.

    PRTG does everything we need it to do and more. Ease of use, ease of management and maintenance and clarity of monitoring of hundreds of different types of device and service gives this a large advantage over other products on the market that I have tried. I would definitely recommend it to anyone who needs a network monitoring product in their environment and even to people who don't know they need a solution yet!

    It's very important that de project's teams have different member of the TI. We have learned too late the importa of Security Analyst at the design architecture moment. We have to rebuild part of the implementation for made this big mistake.

    Cost efficiency is the main reason which we opted [for] Nagios as we were previously using IDERA tool with comprehensive database monitoring solutions, but the slow performance we are getting while monitoring the instance of the database.

    PRTG offers more versatility in monitoring when compared to the other solutions we tested. The other solutions were also limited as far as customization options, which made them less adaptable to our networks. When compared to Auvik, for instance, we prefer PRTG as it offers immediate notifications through the desktop client - not limited to email notifications as with Auvik. We also appreciate the fact that PRTG can be self/on-prem hosted vs Auvik's cloud model. This makes for an easier deployment and less firewall adjustments to allow traffic to cloud-hosted solutions.

    • The ability to analyze multiple pieces of information in one place, especially with historical data, has saved our IT department time and headaches. It would be so much more difficult to trace an issue without PRTG, just relying on event logs and an open task manager window.
    • The cost is not cheap, so it's an expense that hits the bottom line like everything else. Figure in hardware costs as well, ideally a server outside of your main environment.
    • I keep saying this, but the historical data piece is worth so much. There's really no good way to collect all of that information in one place without something like PRTG. And that definitely saves time and money in the long run.
