This guide is about finding the actual problem fast.

The plant manager walks into your office with a question that makes your stomach drop. "Can you check if the network is causing issues with the production line?" You open your monitoring dashboard.

The figures in the recent New Relic 2024 State of Observability report are difficult to ignore. For financial services companies, the cost of high-impact IT outages has climbed to a median of $1.8 million per hour.

First the network monitoring tool. Then the server dashboard in that other platform. Then you need to check application logs somewhere else entirely. And you're sitting there, half-asleep, trying to piece together what actually went wrong before your CEO starts sending emails.

If you've been following the virtualization market lately, you know things have gotten... interesting. The Broadcom takeover of VMware sent shockwaves through the IT world, with price increases that had many of us doing a double-take.

Another year done. And honestly? When we look back at everything that happened with PRTG in 2025, we're still amazed at how much we managed to pack into twelve months.
