Custom alerts and data visualization let you quickly identify and prevent all kinds of network issues.
ipMonitor excels at uptime, downtime, and basic network performance monitoring, and its one-time, perpetual license might seem attractive at first glance. The trade-off is that it comes with a high upfront cost, requires optional add-ons for maintenance and support, and may struggle to handle larger, more complex environments.
PRTG, on the other hand, is a full-stack network monitoring solution that can handle even the most complex networks. And, its fully-featured free forever plan means you can get started at no cost — great if you're a small business with limited budget.
Don’t track just uptime and downtime, but every variable that could impact performance: bandwidth, latency, APIs, DNS, VPNs, Linux and other operating systems. PRTG builds a complete, real-time snapshot of your network infrastructure, bringing all the disparate data points together in one place and organizing them in a way that makes it easy for IT operations teams to put it to work.
Oh, and it’s resource-light and straightforward to set up, too.

With 250+ preconfigured sensors plus the ability to create your own, PRTG can track every variable and metric you can think of… and even those you don’t think you need to monitor right now. Which means you’ll always know exactly what's going on with your network, no matter how large or complex it is.
Get up and running in minutes, regardless of whether you have a small local network or complex distributed infrastructure. Auto-Discovery detects all connected hardware and software and starts monitoring key metrics right away. You can leave your dashboard as is, or customize every aspect of it to suit.
Troubleshooting, optimization, and capacity planning don’t get any simpler. PRTG gives you round-the-clock, granular data on servers, routers, firewalls, DNS, and more, supports all major monitoring protocols, and alerts you automatically as soon as something doesn’t look quite right, so you can pinpoint bottlenecks, vulnerabilities, and other issues (and solve them) faster.
Don’t be fooled by PRTG’s ease of setup and use. Our network monitoring software can be tailored to your exact requirements. Deploy it on premises, in the cloud, or as a hybrid solution and access customizable dashboards, graphs, and other visualizations, as well as performance and alert thresholds. How’s that for full stack observability?
Simple. Transparent. Predictable. PRTG's sensor-based pricing model gives you access to all network monitoring functionalities and expert support. Even on our free plan. That means you’ll always know exactly how much your bill will amount to. Plus, you can easily upgrade or downgrade as your needs change.

PRTG is set up in a matter of minutes and can be used on a wide variety of mobile devices.
We also compared PRTG with other monitoring tools:
SolarWinds is a module-based platform. But this also means that scaling your monitoring can quickly cost hundreds of thousands of dollars if you want to get a comprehensive software bundle.
PRTG and ManageEngine might seem similar at first. However, with ManageEngine, you have to choose between individual functions and purchase several modules to access the full range of features.
Zabbix is open-source software with a strong community support. But it requires lots of manual configuration work to install and set it up. You also need to install agents on the monitored systems.
The basic version of the open-source tool Nagios is free of charge. But most users spent many hours to set up and customize the tool. In case of problems, browsing through forums is often the only solution.
Real-time notifications mean faster troubleshooting so that you can act before more serious issues occur.

Choosing between Paessler PRTG and ipMonitor depends on several factors, such as your specific network monitoring needs, budget, and technical resources available in your organization.
PRTG is ideal:
ipMonitor might be your choice:
PRTG hands down, for one simple reason. It's an end-to-end, full-stack IT network monitoring solution.
Solarwinds’ ipMonitor specializes in uptime and downtime monitoring. It's great for keeping an eye on hardware and software performance and minimizing disruption, but doesn't have the capabilities to handle larger, more complex networks. Nor can it monitor more advanced metrics.
PRTG, by contrast, can carry out application performance monitoring, keep an eye on network devices, plugins, and even operating systems, handle in-depth server monitoring, and distributed monitoring, and even monitor temperature, humidity, and other environmental variables. This means you have real-time visibility into every aspect of your network.
ipMonitor and PRTG are both simple and straightforward to set up. In ipMonitor's case, however, this partly reflects its limitations. Specifically, it focuses on uptime, downtime, and basic network monitoring.
PRTG is simple and straightforward to set up, even if you have a complex, distributed network or advanced metrics to monitor. Auto-Discovery detects every hardware, software, and virtual component within a given IP address range, assigns the right sensors, and starts gathering data. Which means you can be up and running in minutes, regardless of the size and complexity of your IT infrastructure.
ipMonitor charges a one-time fee based on the number of endpoints you'd like to track. That might seem attractive at first glance. The catch is that you don't get access to updates, maintenance, or support. You'll need to pay an annual fee for them, which, while optional, is recommended for most organizations. You'll also need to upgrade your license and, so, pay additional fees if your network grows, and you need to monitor more endpoints.
PRTG uses a subscription-based model, but all features, upgrades, and support are included on every single tier, even the free plan. This means you can get started at no upfront cost. And, because we price per sensor, your costs are transparent and predictable: you pay for the metrics you want to monitor, not to access more functionality, or for updates and support
In PRTG, “sensors” are the basic monitoring elements. One sensor usually monitors one measured value in your network, for example the traffic of a switch port, the CPU load of a server, or the free space on a disk drive. On average, you need about 5-10 sensors per device or one sensor per switch port.
Paessler conducted trials in over 600 IT departments worldwide to tune its network monitoring software closer to the needs of sysadmins. The result of the survey: over 95% of the participants would recommend PRTG – or already have.
