Why should I use a tool to monitor my servers?
Detect server hardware malfunctions at once
CPU errors, memory overloads, faulty network cards...it seems like something is always going wrong with server hardware. In reality, this is a normal part of wear and tear, especially when your IT infrastructure grows and incorporates more and more devices which don't always stem from the same manufacturer. With PRTG, you’re sure to be covered. It comes with preconfigured sensors for all the most popular server hardware and manufacturers.
Quickly eliminate server bottlenecks
Even brief spikes can generate peak loads in the system. And this can cause any part of the network to go haywire. Most of the time, it’s your switches, routers, or servers that take the hit. Thanks to the PRTG dashboard, you’ll immediately see if a bottleneck appears. What’s more, you can configure the PRTG notification system to have alerts displayed on the screen or sent to a smartphone or other device. As a result, you can identify problems in seconds and take all the necessary actions to fix them.
Keep an eye on your virtual servers
Many companies use both physical and virtual servers. It’s not enough to only monitor physical servers. Virtual servers – and their host hardware – must also be monitored. PRTG comes with preconfigured sensors for VMware, Citrix, HyperV, and more.
Case study: How PRTG customers use our server monitoring tool
“One of our most important tasks involves the daily logging of customer transaction counting protocols in SQL databases. Sometimes this integration fails. PRTG comes with SQL sensors that warn us if an integration is about to fail. It also shows us how much memory is available on our local servers. As a result, we always know how much data can be copied there. PRTG is the fastest and easiest way to access this vital information.”

Nagios is open-source software for network monitoring. Many of our customers used Nagios before switching to PRTG. On the surface, Nagios is a free open-source tool. But compared to PRTG, it is much more difficult to configure. PRTG also beats Nagios when it comes to the reliability and presentation of data. Discover our in-depth comparison here: Nagios vs. PRTG.
Like PRTG, SolarWinds is proprietary network monitoring software that comes with server monitoring. SolarWinds often vies with PRTG for the top spot in rankings. The advantage of PRTG: Our software is all-inclusive. Among other things, it also monitors Cisco devices. For a detailed comparison, see: SolarWinds vs. PRTG.
