PRTG network analysis tool: From “No!” to “Go!” in minutes, not hours
How PRTG defines sensors
In PRTG, “sensors” are the basic monitoring elements. One sensor usually monitors one measured value in your network, e.g. the traffic of a switch port, the CPU load of a server, the free space of a disk drive. On average you need about 5-10 sensors per device or one sensor per switch port.
Enjoy comprehensive monitoring
No network's too large or complex for PRTG. With 250+ preconfigured sensors and an intuitive, highly customizable dashboard, you can spot trouble and work out whether it's a hardware, software, or system issue with a few clicks.
Analyze
historical data
Go back as far as you need to, and home in on when the problem started. You can also generate custom reports you can use to get your higher-ups up to speed with the current state of your infrastructure… and let them know it's time to upgrade.
Receive automatic alerts
Prevention's better than cure. PRTG's configurable alerts notify you at the first sign of a possible problem, so you can take prompt action (and look good with your colleagues and your boss). Choose from various notification methods like email, SMS, or push notification.

Network analysis and diagnostics with PRTG in a nutshell
PRTG comes with many native sensors that keep a constant eye on specific parameters. For each parameter, you can set your preferred threshold. PRTG alerts you if performance falls under the threshold, so you can immediately check what's going on and sort it.
PRTG analysis and diagnostics includes:
Server diagnosis
Your DNS server is down and you don’t know why? Our DNS v2 sensor monitors response times and domain name resolution so you can quickly analyze the root cause of an issue. Keep a constant eye on all your physical and virtual servers, including web servers, mail servers, cloud services, and database servers.
Log analysis
Use our Event Log (Windows API) or WMI Event Log sensors for detailed event log monitoring. In the event of a sudden spike in log entries – which you can filter by log files, event types, sources, messages, etc. – PRTG will send you a notification at once. It’s also possible to have PRTG read and monitor the logs of target systems such as your CDN.
Network traffic analysis
With the Packet Sniffer sensor or our various sensors for flow monitoring (NetFlow, sFlow, jFlow, and IPFIX), it’s easy to always keep an eye on bandwidth and network traffic. PRTG filters traffic data according to IP addresses, data types, data packets, and protocols to quickly get to the root of network connection problems.

Network analysis and network diagnostics: FAQ
1. What is PRTG network analyzer and diagnostics?
PRTG is a proprietary software tool that monitors the performance and health of every component on your network. The intuitive dashboard shows you which devices, applications, web services, and other aspects of your IT infrastructure are running smoothly, and whether any are underperforming or causing issues.
You can then use a specialized diagnostic tool – many hardware manufacturers (such as HPE or Dell) and operating systems (Windows, macOS, and Linux) for instance, offer such tools out of the box – to get to the root of the problem and fix it.
2. Why analyze and diagnose your network with PRTG?
A network analysis and diagnostics software like PRTG enables you to be proactive, spotting and addressing issues before they cause crashes and other serious disruptions. And because everything is monitored automatically and the data is all in one place, the process is easier and quicker. You may even discover dependencies you might not have considered before.
3. Analysis vs diagnostics: what's the difference?
First you analyze, and then you diagnose. Think of it this way. Analysis is your doctor keeping an eye on your health and investigating any unusual symptoms. And diagnosis is when they use what they've learned to identify what's causing those symptoms and formulate a treatment plan.
PRTG works in much the same way, monitoring the state of your network, alerting you when something doesn't look right, and helping you identify where the problem lies.
4. Can you give me some network analysis tips?
Network analysis involves examining relationships and connections among various elements within a system. Here are some tips to get you started:
- Define your objectives: Clearly outline what you aim to achieve through network analysis. Whether it's understanding relationships, identifying key players, or measuring the flow of information, having a clear goal will guide your analysis.
- Data preparation: Ensure your data is formatted properly. Nodes (individual entities) and edges (connections between nodes) should be clearly defined. Data cleaning and transformation might be necessary to standardize information.
- Network visualization: Visual representation is powerful for understanding network structures. Experiment with different layouts, colors, and node sizing to highlight important elements or patterns within the network.
- Dynamic network analysis: If applicable, consider the temporal aspect of networks. Analyze how connections change over time to gain insights into evolving relationships.
- Iterate and refine: Network analysis often involves an iterative process. Refine your approach based on initial findings and feedback, adjusting parameters or exploring different analytical methods as needed.
5. What is a sensor in PRTG?
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.
