When you lack visibility into your network traffic, resolving network congestion quickly is often just a dream. It can seem like a hodgepodge of shoring up network issues and identifying random root causes. Let our comprehensive, single-solution network monitoring software give you the peace of mind you need and deserve. Paessler PRTG’s packet analysis capabilities are always on and always alert.

Warning

Identify and troubleshoot bottlenecks with ease

Spot bandwidth bottlenecks and unusual traffic spikes faster than you can say “packet sniffer.”. Using advanced packet capture and packet sniffing techniques, PRTG helps you identify suspicious activities and other oddities that could indicate a potential security breach or network issue.

When something fishy happens, PRTG helps you pinpoint the problem down to the specific IP address. It’s like having X-ray vision for your network!

Sensor

Customize sensors for faster incident response

One size doesn’t fit all, especially when it comes to network monitoring in unique environments. PRTG’s extensive standard sensor types and powerful API allow you to customize sensors to fit your department’s unique needs.

Whether you’re focusing on packet analysis or real-time traffic monitoring using various flow protocols (NetFlow, jFlow, sFlow, IPFIX), you can set up PRTG to your heart’s content.

Coffee

Experience effortless, central network monitoring

Stop juggling flaming torches. Simplify your life and your infrastructure monitoring with our all-encompassing software solution. PRTG simplifies your network monitoring by providing an all-in-one packet analyzer and packet sniffer.

With everything in one place, you can say goodbye to the circus act and hello to a more efficient, stress-free monitoring experience.

Lock

Implement robust network security mechanisms

Your network deserves the best bodyguard your money can buy. PRTG’s rock-solid security measures ensure that all communications between the PRTG server, probes, and clients are secured via SSL/TLS. 

Only the most secure ciphers for SSL/TLS connections are allowed, keeping your data and network traffic safe from prying eyes. Your monitoring data is safe, and so is your sanity.

What packet inspection looks like in PRTG

Diagnose network issues by continuously tracking and analyzing the packets that flow through your network. Show response time, bandwidth usage, traffic by port, IP address, and other key metrics in real time. Visualize monitoring data in clear graphs and dashboards to identify problems more easily. Gain the overview you need to troubleshoot all kinds of packet inspection issues.

5 more reasons to choose PRTG as your packet analyzer

Track your entire network

PRTG is the multi-tool of network monitoring. It  captures and analyzes data packets across both Ethernet and Wi-Fi networks, ensuring you get a complete view of your entire infrastructure.

By monitoring network packets and examining their headers, you can identify issues at the granular level, eliminate weak spots, and reduce the man-hour overhead and complexity of managing multiple monitoring solutions. It’s all-in-one, and it’s all awesome.

Critical security points? Locked down

PRTG keeps an eagle eye on critical security points. As a network protocol analyzer, PRTG classifies network traffic, measures Quality of Service (QoS), and detects unusual activity between network components and behavior by device or user.

It also monitors critical services like DNS and FTP, helping you debug issues quickly. Better than having Sherlock Holmes watching your infrastructure for hackers and ne’re-do-wells.

Instant insights on the move

Sometimes, it seems like you can never get away from your desk. There’s always something keeping you chained down, this user or that alarm. With PRTG, you get continuous real-time monitoring of your network traffic, displayed through structured graphical maps and dashboards.

The PRTG mobile app allows you to monitor your network remotely so you can troubleshoot from your couch, your favorite coffee shop, or even the beach.

It’s quick and easy to set up

Setting up network monitoring can be complex with many solutions, but PRTG makes it simple. As an agentless monitoring solution, PRTG requires no complicated installations, allowing you to get started quickly and efficiently.

This ease of setup frees up sysadmins to focus on other critical IT tasks, ensuring your network monitoring is up and running with minimal hassle.

Get proactive alerts for a swift response

PRTG helps minimize the impact of system failures by ensuring they’re addressed as quickly as possible or even prevented in advance. With customizable alarms, you’ll be the first to know if something goes awry, a virtual signal alerting you to network troubles.

Its built-in alarm system sends alerts via email, SMS, or push notification at the first sign of a problem, allowing you to take immediate action to maintain network performance and security.

Packet Analyzer: FAQ

 

What is a packet analyzer?

A packet analyzer, also known as a network analyzer, protocol analyzer, or sniffer, is a tool or software application that intercepts and analyzes data packets traveling over a network. It allows users to inspect, monitor, and troubleshoot network traffic in real-time or analyze it later from saved logs.

Why use a packet analyzer?

A packet analyzer is essential for understanding the detailed behavior of your network. It helps you diagnose network issues, enhance security, and ensure optimal performance by analyzing the data packets flowing through your network.

What does PRTG's packet analyzer examine?

PRTG’s packet analyzer examines various aspects of network packets, including packet headers, payloads, protocols (such as TCP, DNS, and FTP), traffic patterns, and potential security threats. This detailed analysis helps in troubleshooting, optimizing performance, and identifying unauthorized activities.

How does PRTG analyze packets?

PRTG uses advanced packet capture and packet sniffing techniques to gather data packets traversing the network. It then analyzes these packets to provide insights into traffic patterns, protocol usage, and potential issues. PRTG’s sensors are designed to capture and analyze data in real-time, offering a comprehensive view of network activity.

What are the key features of PRTG's packet analyzer?

PRTG’s packet analyzer provides detailed packet capture, real-time packet sniffing, protocol-specific analysis, traffic pattern identification, and security threat detection. These features allow you to monitor network performance, debug issues, and enhance security.

Does PRTG provide historical data on packet analysis?

Yes, PRTG stores historical data, allowing you to analyze packet trends over time and identify recurring issues. This historical data helps in long-term network planning and optimization.

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.

We asked: would you recommend PRTG? Over 95% of our customers say yes!

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.
