PRODUCT OVERVIEW

Is your ISP as performant as you need? PRTG knows!

Imagine you are a sysadmin at a mid-sized company, and your team is suddenly bombarded with complaints about slow internet speeds and intermittent connectivity. The problem? Your ISP's performance has declined, but locating the exact cause is a challenge.

With Paessler PRTG, you can quickly set up real-time monitoring of your ISP's bandwidth and latency, uncovering the source of the issue – a bottleneck at the ISP's end during peak hours.

Customizable alerts in PRTG notify you as soon as the problem resurfaces. This allows you to take immediate action or work with your ISP to resolve the issue. The result? Minimal downtime, satisfied users, and peace of mind knowing your network is running like a charm.

Monitoring Internet Service Providers: FAQ

 

What is ISP monitoring?

ISP monitoring involves tracking the performance of your Internet Service Provider (ISP) to ensure reliable and efficient connectivity. This includes monitoring bandwidth usage, latency, packet loss, and uptime to identify any issues that could affect your network's performance.

Why is ISP monitoring important?

Monitoring your ISP is necessary to maintain optimal network performance. It allows you to detect and address issues like slow internet speed, outages, and poor response time before they impact your users. It also helps you hold your ISP accountable to the terms of your service agreement.

How does PRTG help in monitoring ISP performance?

PRTG provides real-time monitoring of key ISP performance metrics such as bandwidth, latency, and packet loss. It offers customizable alerts, detailed reporting, and visual dashboards that give you a clear overview of your ISP’s performance.

Can PRTG monitor multiple ISP connections?

Yes, PRTG is capable of monitoring multiple ISP connections simultaneously. This is especially useful for businesses with redundant internet connections or various endpoints, allowing you to compare performance and ensure that failover mechanisms are working effectively.

How does PRTG handle bandwidth analysis?

PRTG offers comprehensive bandwidth analysis by tracking data usage across your network. It helps you identify bandwidth hogs, monitor traffic patterns, and understand peak usage times. This allows you to optimize your ISP network usage and ensure efficient allocation of resources.

Does PRTG support SLA monitoring with my ISP?

Yes, PRTG can help you monitor your ISP’s compliance with service-level agreements (SLAs). By tracking metrics such as uptime, latency, and packet loss, PRTG enables you to generate reports that can be used to verify that your ISP is meeting its contractual obligations.

What security features does PRTG offer for ISP monitoring?

PRTG enhances the security of your network by monitoring for unusual traffic patterns, unauthorized access attempts, and other indicators of potential security breaches. It provides alerts for suspicious activities and help you respond quickly to potential threats.

How does the flexible licensing in PRTG benefit ISP monitoring?

The subscription-based licensing model of PRTG offers flexibility as your monitoring needs grow. Whether you’re expanding your WAN or adding more ISP connections, PRTG’s scalable licensing ensures that you only pay for what you need, making it a cost-effective solution for businesses of all sizes.

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.
