3 more reasons why to use PRTG as your server monitoring tool
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 normal wear and tear, particularly if your IT infrastructure grows and incorporates more and more network devices that are not always produced by the same manufacturer. PRTG has got you covered – our server monitoring solution comes with preconfigured sensors for the most popular server hardware manufacturers.
Quickly eliminate server bottlenecks
Even brief traffic spikes can generate peak loads in your IT infrastructure, which can cause any part of the network to go down. Most of the time, it’s your switches, routers, or servers that take the hit. Thanks to our customizable dashboards and easy-to-read graphs, you can see at one glance where a bottleneck is about to occur and take immediate action to troubleshoot the issue – before something more critical happens.
Keep an eye on your virtual servers
Many companies use both physical and virtual servers. However, it’s not enough to only monitor your physical servers – you should also constantly monitor the health and performance of your virtual servers in addition to the host hardware that runs your virtual machines. PRTG comes with various preconfigured sensors from different vendors for monitoring your virtual environment, for example, VMware, Citrix, or Microsoft Hyper-V.
Server monitoring tools put to the test: Prices, features, and more
These days, system administrators are spoiled for choice. The market is literally overflowing with monitoring tools and each of these tools has its pros and cons. We’ve compared some of them with PRTG.
Nagios
Nagios is open-source software for network monitoring. Many of our customers used Nagios before switching to PRTG because it is free of charge.
Compared to PRTG, however, it is much more difficult to configure. PRTG also beats Nagios when it comes to the visual presentation of data. For a more detailed comparison, see: Nagios vs. PRTG.
SolarWinds
Like PRTG Network Monitor, SolarWinds NPM is proprietary network monitoring software that also monitors server hardware.
While one license of PRTG includes all monitoring features, however, you need different products from SolarWinds to monitor, for example, network traffic or application performance. For a more detailed comparison, see: SolarWinds vs. PRTG.
Zabbix
Zabbix is another free, open-source network monitoring tool that offers more visualization options than Nagios.
If you think about choosing between Zabbix and PRTG, always keep in mind the time that you'll need for extensive configuration work, which you won't need with our easy-to-use monitoring software PRTG. For a more detailed comparison, see: Zabbix vs. PRTG.
