    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.

    Great for standard web application performance monitoring, analytics and error reporting. Shows line level code errors, gives insight into performance issues (plugins, API issues, etc.). Automation and scheduled scanning in production gives client visibility into 'after deployment' value. Also lets a relatively small number of developers keep tabs on a handful of different site/applications without needing a bunch of tools. The UI is pretty complicated and can be overwhelming for new users. Documentation could be better for the learning curve,

    Pros
    Paessler
    • Switch monitoring and finding out if there are communication issues or throughput alerts are reached
    • Big picture view of the whole infrastructure and what is functioning and what is not
    • Uptime tracking is great and lets us know for how long a device is down or overall uptime

    • Great web interface. Lots of data available in a really clean format, with filtering options and more.
    • Per-user exception tracking. User is complaining about something being broken? Look up their account ID in Sentry and you can see if they've run into any exceptions (with device information included, of course).
    • Source map uploading. Took a little while to figure this out but now we have our deploy script upload sourcemaps to Sentry on each deployment, meaning we get to see stack traces that aren't obfuscated!
    • Very generous free tier – 10,000 events per month. We're nowhere near that yet.

    Cons
    Paessler
    • 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

    • Alert Configuration. Would be really helpful to have multiple logical groupings within the "If" section of a single configurable alert.
    • Alert Copying. Being able to copy an alert from one project to another would be super beneficial.
    • Alert Tags. Better UI around how we select which tags are getting sent with each alert instead of a tiny text box.

    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.

    Usability
    Paessler
    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.

    Its incredibly versatile, but that leads to complexity for the uninitiated, which can be intimidating. Nevertheless its a well polished product, in our case leading to only using it for a focus on frontend is still more cost effective than buying a one-to-rule-them-all tool...

    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.

    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.

    It is cheaper and offers better support for front-end applications for enterprise large environments with more then 30 scrum teams and hundreds of micro frontend applications. The configuration options, both with the agent and from the user interface, are superior to other tools, and the documentation is also very easy to use.

    Return on Investment
    Paessler
    • 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.

    • So it has helped us for quick error resolutions.
    • From dashboard we are able to assign errors to particular member and see when its resolved.
    • Without customer informing us about errors we know what happened in real time helps in customer service also.
