The internet pretty much runs the world right now, and servers run the internet. That's how important these powerful enterprise computers are.

Businesses rely on servers to store and process data of all kinds, so if one of them isn’t performing as it should, then the data that businesses rely on for mission-critical tasks won’t reach its destination on time, or at all. Server monitoring tools are the best way for enterprises to ensure that their servers, both physical and virtual, are operational and functioning at a manageable level. 

Server monitoring software is an essential tool for system administrators, because it allows for automated reporting, scheduled checks and pre-emptive warnings about the health of your many servers within your operating environment. Good server monitoring software is able to check everything about your system and notify admins in advance of a problem.

Which server monitoring tools are the best for your company? That's for you to decide, but we can help bring you timely, pertinent third-party information.

We at eWEEK have compiled a list of the best server monitoring tools to help you make a decision. These tools should definitely be considered by any enterprise looking for a solution to improve or manage the performance of their server infrastructure.

Here we go, in alphabetical order:

Value proposition for potential buyers

SolarWinds Server and Application Monitor is a server and application monitoring solution that allows IT teams to monitor the status and performance of servers. The tool monitors a server’s critical hardware components, including fan speed, device temperature, power supply, CPU usage, and battery usage. SolarWinds also supports customizable server monitoring, letting IT departments work with pre-established templates or import custom scripts that work with their deployments.

Key values/differentiators

As IT staff take on new clients, they need to be able to monitor everything on their network—not just servers and workstations—to help ensure complete coverage. Without visibility into the whole network, admins may lack the information they need to fully resolve issues.

The network device monitoring feature in SolarWinds RMM is designed to provide visibility into the devices on managed networks. This feature was built to allow admins to quickly detect and monitor all connected devices, which can potentially help limit unexpected expenses and troubleshooting time from unforeseen issues—and give them greater control of the networks they manage. 

Remote monitoring and management (RMM) is the process of supervising and controlling IT systems (such as network devices, desktops, servers and mobile devices) by means of locally installed agents that can be accessed by a management service provider.

  • Monitoring for a wide range of devices: Monitor network devices, such as printers, firewalls, routers, switches, uninterruptible power supplies (UPS), and more.
  • Easy discovery: Monitor devices on your user networks and search for devices under any subnet.
  • Asset information: Import devices connected to each managed subnet with details such as MAC Address, IP, operating system, firmware version, and hostname.
  • SNMP check: Run checks for in-depth monitoring of hardware health, performance, and utilization.
