3 ways PRTG Internet monitoring helps you manage Internet usage and network activity

Paessler PRTG monitors your bandwidth and hardware round the clock to measure your Internet usage and keep a constant eye on the capacity of your network. In the event of a problem or error, our Internet usage monitoring software will immediately alert you based on custom thresholds so you can take action to prevent downtime.

Keep your Internet up and running

Faulty switches and routers can wreak havoc on your network. Often this hardware is damaged or missing an important update.

PRTG sensors let you monitor the hardware of countless different manufacturers, and always keep an eye on your CPU, memory capacity, hard disks, and more.


Monitor network bandwidth usage

As your company network grows, so does its need for applications. Over time, these applications gradually eat away at your bandwidth.

PRTG’s bandwidth monitoring provide you with an overview of your bandwidth consumption, while our flow and packet sniffer sensors show you which devices and applications are putting the greatest strain on your network.

Eliminate network bottlenecks

Every network has bandwidth hogs. Most of the time, these bottlenecks appear in the local network and are only temporary.

PRTG keeps your network in tip-top shape with 24/7 monitoring of devices, bandwidth, traffic, and more. This means you'll immediately see if bottlenecks arise while performing backups or running certain applications








What Internet usage monitoring looks like in PRTG

Diagnose network issues by continuously monitoring network bandwidth usage and analyzing Internet traffic, website speed, and your Internet connections. Show bandwidth utilization and other performance stats in real time and visualize data in graphic maps & dashboards to identify problems more easily. Gain the visibility you need to troubleshoot your Internet usage and traffic.

Monitor Internet usage: FAQ


Why can Internet usage be too high in organizations?

High Internet usage can be due to several factors, which can be broadly categorized into user behavior, technical issues, and external factors. Here's a detailed breakdown:

User behavior

  • Streaming and downloads: Streaming high-definition videos, music, or other media consumes a large amount of data. Similarly, downloading large files or frequent software updates can lead to high usage.
  • Cloud usage: Using cloud storage and services for backing up data or accessing files remotely can result in substantial data usage.
  • Multiple devices: Having multiple devices connected to the Internet simultaneously can increase overall usage.

Technical issues

  • Automatic updates: Operating systems, applications, and devices often download updates automatically, consuming bandwidth without the user’s active involvement.
  • Background processes: Applications running in the background can use the Internet for various purposes, such as syncing data, checking for updates, or sending usage statistics.
  • Network misconfigurations: Poorly configured networks or devices can lead to inefficient data usage. For example, some devices may repeatedly attempt to connect to the Internet if they experience connectivity issues.

External factors

  • ISP data caps: Some Internet Service Providers (ISPs) impose data caps, which can lead to high usage notifications or throttling once the cap is exceeded.
  • Security issues: Malware or unauthorized access to a network can lead to high Internet usage. For instance, a compromised device may be used to send spam or participate in a botnet, consuming large amounts of data.
  • High traffic times: During peak hours, when many users are online simultaneously, overall data consumption can be higher, affecting the perceived Internet usage.

How can I monitor my Internet usage?

To manage and monitor Internet usage, you can:

  • Check the data usage reports provided by your ISP
  • Use network monitoring tools or software like Paessler PRTG to track Internet consumption by different devices and applications
  • Set limits or controls on devices to manage data usage effectively
  • Regularly update and secure devices to prevent unauthorized access and reduce background data consumption

Why should I monitor Internet usage?

Monitoring Internet usage is important for several key reasons. By tracking Internet usage, you can ensure efficient bandwidth allocation and prevent network congestion and improving overall performance. Monitoring also helps identify and mitigate security threats such as malware, unauthorized access, and data breaches. What’s more: Internet usage data provides insights that are crucial for future network capacity planning and upgrades.

How do I use PRTG as an Internet consumption monitor?

Paessler PRTG is an all-in-one network monitoring tool that also tracks and analyzes Internet traffic. Our tool uses SNMP (Simple Network Management Protocol), NetFlow, sFlow, jFlow, and packet sniffing to monitor the bandwidth usage of devices and connections. By setting up sensors for network interfaces, PRTG can also measure traffic going in and out.

  • SNMP: SNMP sensors poll devices for traffic counters, providing data on bandwidth usage.
  • Flow technologies: NetFlow, sFlow, jFlow, and IPFIX sensors analyze the flow of data packets, offering detailed insights into which applications and services are consuming bandwidth.
  • Packet sniffing: PRTG captures network packets and analyzes their content to determine what type of traffic is being transmitted.

How can I track Internet data usage with PRTG?

Paessler PRTG stores historical data on Internet usage and more, which you can use for trend analysis, identifying peak traffic times, and optimizing resource allocation as well as your entire network.

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.


PRTG the multi-tool

PRTG: The multi-tool for sysadmins

Adapt PRTG individually and dynamically to your needs and rely on a strong API:

  • HTTP API: Access monitoring data and manipulate monitoring objects via HTTP requests
  • Custom sensors: Create your own PRTG sensors for customized monitoring
  • Custom notifications: Create your own notifications and send action triggers to external systems
  • REST Custom sensor: Monitor almost everything that provides data in XML or JSON format
