Best Server Monitoring Tools & Software for Windows/Linux (FREE & PAID)

best server monitoring tools for windows and linux

Marc Wilson

Server Monitoring is, hands down, the most important task any IT professional will do in their daily routine to ensure that all production servers and applications are running at peak performance without any hiccups.

Employing the best server monitoring tools and software in your environment will not only ensure that your machines are running smoothly, but will keep your job secure as well. There's an old saying about Backups in IT departments: “Have Good Backups, Or a Good Resume” – this holds true for keeping servers up and healthy as well.

With all that said, we're going to go through a large list of software that will help you keep an eye on your infrastructure. We're hoping that our list will help you determine which software suite will work in your environment, as each is wildly different than the next.

Here is our list of the top server monitoring tools:

  1. SolarWinds Server & Application Monitor – FREE TRIAL Service that watches the resources on a server as applications use them and reports on capacity problems through an alerting mechanism. Installs on Windows Server.
  2. Paessler PRTG – FREE TRIAL A bundle of monitoring tools that cover server performance issues as well as network and application performance. Installs on Windows Server.
  3. Site24x7 Server Monitoring – FREE TRIAL A cloud-based monitoring platform that covers networks, servers, and applications that includes hypervisor monitoring.
  4. SentryOne SQL Sentry – FREE TRIAL A monitoring system for SQL Server that also covers the underlying support structure including Windows and Linux servers. Available for Windows Server or as an Azure service.
  5. Progress WhatsUp Gold A network performance monitor that can be extended to monitor servers and applications as well. Installs on Windows Server.
  6. ITRS OP5 Monitor An infrastructure monitoring system that includes business tracking procedures. Installs on Linux and can run on Windows Server over a hypervisor or on cloud platforms.
  7. ManageEngine OpManager A server and network monitoring package that includes virtualization performance tracking. Installs on Windows Server and Linux.
  8. Incinga 2 A free infrastructure monitor that was developed from a fork of Nagios Core that incudes server monitoring. Installs on Linux.
  9. Zabbix A free systems monitoring package that includes server monitoring. Runs on Linux, macOS, and Unix.
  10. Nagios XI an infrastructure monitoring system that includes server monitoring functions and is based on the free Nagios Core.
  11. OpenNMS Horizon A free system monitoring package that is primarily a network monitor but also has server monitoring capabilities.

In terms of monitoring capabilities, many of these software suites provide the functionality, reports and alert systems that are needed to ensure that everything is running top notch. We've included some open-source options as well, as some engineers and administrators are using them in their environments on a daily basis – although we like to have a support team behind the product if questions or support issues arise, as our main job is to keep servers healthy and running at all times, not configuring open-source software to do what we want it to do.

Best Tools for Server Monitoring and Management of 2021:

Below you'll find a list of our top choices and a detailed description about them and some screenshots of their Interfaces and options.

1. SolarWinds Server & Application Monitor – Recommended Choice!

The capabilities that SolarWinds SAM has in terms of flexibility and features gives it the clear advantage when it comes to finding a solution for your monitoring needs. We recently did an article on some alternatives to nagios and the only software package that had the ability to Import Nagios Scripts natively was SolarWinds SAM. Many of the other software packages had nice templates for creating/replicating the functionality of Nagios scripts, but only SAM was able to import them directly in and start monitoring within a matter of MINUTES!

Conclusion

We hope this overview of the best server monitoring tools and software was helpful in making your decision on which software package you should try out. Almost every single one of these offers a Trial for at least 30 days and they are all very well suited for almost any network.

We are currently using SolarWinds Server and Application Monitor in our network and love it. We suggest it to all our clients and anyone we consult for as it really gives a great overview of your network, the alerts are very easy to setup along with proper reporting.

We have even Migrated users away from Nagios to SolarWinds because they have a built-in Import tool to pull the scripts directly into the software allowing you to be monitoring within a few minutes time.
