PRTG is your ever-vigilant sidekick, highlighting traffic patterns and watching your connection stability, ready to alert you to any downtime or performance degradation.

Net top-tier network traffic analysis

You need top-tier forensic tools to protect your internet connection. Depending on the router, PRTG uses a combination of protocols such as SNMP, NetFlow, sFlow, jFlow, and packet sniffing to give you an exhaustive look into your internet traffic.

Capture every detail of usage patterns, trace bandwidth hogs to their source, and spot suspicious traffic that could signal security threats.

Rapidly repair network nuisances

PRTG continuously monitors your internet connection for any signs of trouble, like high latency, packet loss, or downtime. Its real-time alerts let you swoop in and save the day before issues impact your operations.

Get targeted alerts no matter where

With PRTG’s real-time monitoring, you can keep an eye on your network status anytime, anywhere. Our mobile apps for iOS and Android ensure you stay informed on the go, giving you peace of mind no matter where you are – whether at the office, home, or beach (we won’t judge).

Setting up network connection monitoring isn’t all that fun, but you and your team will be smiling at how easy it can be. With its agentless monitoring capabilities, setting up PRTG internet connection monitoring is a breeze. No PhD required.

We have your back with historical data

PRTG provides you with a wealth of historical data, available as graphs, tables, or logs. This way, you can easily generate custom reports for further analysis and future capacity planning – and also check if your ISP meets their service level agreements (SLA).

Explore our preconfigured PRTG sensors for internet connection monitoring

PRTG comes with more than 250 native sensor types for monitoring your entire on-premises, cloud, and hybrid cloud environment out of the box. Check out some examples below!

Ping v2

The Ping v2 sensor sends an Internet Control Message Protocol (ICMP) echo request ("ping") from the probe system to the parent device to monitor its availability. It can show the following:

• Response time

• Packet loss

• Target status

• Minimum and maximum ping time

HTTP v2

The HTTP v2 sensor monitors a web server. It can show the following:

Number of bytes received
Web page or element loading time
Response code of the target server

Ping Jitter

The Ping Jitter sensor sends a series of Internet Control Message Protocol (ICMP) echo requests ("pings") to a URI to determine the statistical jitter. It can show the following:

Execution time
Statistical jitter value

DNS v2

The DNS v2 sensor monitors a Domain Name System (DNS) server, resolves domain name records, and compares them to a filter. It can show the following:

Number of matched records (if you use a filter)
Number of records
If records were resolved
Response time

See the PRTG Manual for a list of all available sensor types.

How PRTG monitors and troubleshoots internet connectivity

Check availability and load time

There are several ways to monitor your network’s internet connection with PRTG:

You can use the Ping v2 sensor to ping the IP address of web pages at regular intervals and check if they’re reachable.
The HTTP v2 sensor monitors the load time of a website or component. It lets you check the length of time required to load specific content.

Solve internet connectivity issues

If you have issues with your internet connection and need to know where the problem lies pinpoint the location as follows:

First, figure out all hops between you and the device you are trying to connect with the Traceroute Hop Count sensor
Then create a device for each of the hosts and add a Ping v2 or a Ping Jitter sensor to each.

Now, you can see which hop or which router is introducing the issues in your connection.

Monitor DNS server performance

If you want to make sure the DNS server is up and running and performing as intended, you can do the following:

Use the Port Range sensor to establish a connection with the service on the particular server. Find out if the device is reachable through the network, or if the operating system on the device is active and managing connections.
Check the performance of your DNS server by adding a DNS v2 sensor to the device and querying a record. Find out if the DNS service is doing its job of resolving DNS records and, if you pick one of your own website DNS records, if your records resolve correctly.

Internet Connection Monitoring: FAQ

Why is internet connectivity monitoring important?

A reliable internet connection, whether via Ethernet or Wi-Fi, is critical for seamless business operations. Downtime or slow internet speeds can disrupt workflows, reduce productivity, and negatively impact customer experience. PRTG ensures your internet connection remains stable by proactively detecting issues and providing real-time alerts.

What metrics should I monitor for my internet connection?

Key metrics include latency, packet loss, bandwidth usage, uptime, and response time. Monitoring these metrics helps identify performance issues, understand traffic patterns, and optimize bandwidth allocation.

How does PRTG detect and resolve connectivity issues?

PRTG uses various sensors to continuously check the availability and performance of your internet connection. It can alert you to issues like high latency, packet loss, or downtime, allowing you to quickly address them and maintain network reliability.

Can PRTG help with bandwidth management?

Yes, PRTG analyzes your internet traffic using NetFlow, sFlow, and packet sniffing. This helps identify bandwidth hogs and optimize your network for better performance, ensuring critical applications have the necessary resources.

Can PRTG monitor both wired and wireless connections?

Absolutely. PRTG monitors both wired and wireless connections, providing comprehensive oversight of your entire network. This ensures you have a complete view of your network’s performance.

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.
