PRODUCT OVERVIEW

“Since using PRTG, we have matured how we report out overall application uptime, maintenance, and mean time between failure for all critical applications to our board of directors. PRTG allows us to not just look at a single event, but to leverage historical data to prevent future failures and to measure how we are making improve­ments over time.”

Bill Sorrells, CTO
Dayton Children's Hospital

“We have found these sophisticated levels of monitoring to be highly effective, improving the end user’s experience of the systems and applications in use, giving us the opportunity to provide a proactive resolution rather than having the end user raise issues.”

Saif Akil, Head of Service Management
Acurus

“Before PRTG, applications and hardware all gave messages, but all separately, so we had to search through hundreds of e-mails to find the problem. It was always only afterwards that we saw that something was going on within the infrastructure. To mitigate the issue, we also considered other software. PRTG stood out because of its user-friendliness, flexibility and minimal consultancy investment.”

Wim Vandenberghe, ICT Manager

website uptime monitoring: FAQ

 

What is website uptime monitoring?

Website uptime monitoring is the process of tracking the availability and performance of your website to make sure it remains accessible to users. PRTG tracks key website metrics, monitors for potential outages, and provides customizable notifications when issues arise. This guarantees that your website offers a reliable experience for every end user.

Does website downtime affect SEO?

Yes, downtime can negatively impact your SEO rankings. Search engines like Google penalize websites that aren’t consistently available, affecting visibility and traffic. Use PRTG to minimize downtime and maintain high availability. This will help to protect your rankings and ensures that end users can always reach your site.

Can PRTG monitor multiple websites at once?

Yes, PRTG is scalable and can track multiple websites simultaneously. This allows you to monitor website performance across different locations and maintain an overview of all your sites, no matter the size of your infrastructure.

How can PRTG improve website speed?

PRTG monitors key performance metrics such as response time, load time, page speed, and upload/download speed, so you can identify slowdowns early. By resolving performance issues promptly, you can optimize website speed and deliver a better experience for end users. This not only boosts satisfaction but also supports SEO and conversion goals.

Does PRTG offer free tools for website monitoring?

Yes, PRTG offers a free version of its monitoring service, allowing you to monitor up to 100 sensors at no cost. This includes tracking critical metrics like response time and SSL health, which are essential for maintaining uptime and performance. If you require advanced monitoring for larger infrastructures, affordable paid licenses are available.

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.

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.
