10 Best Server Monitoring Tools for 2023

Better Stack Team
Updated on January 4, 2023

Sometimes, it is okay to be a control freak, especially when it comes to your architecture. The term itself - server monitoring, is really broad and complex, thanks to a wide array of different types of servers that exist. A server can be a physical device operating on your premises or a virtual machine shared by dozens of others, running their operations independently.

Monitoring and tracking various metrics on all of these different kinds of servers require a specific approach, and while the term software monitoring covers them all, most solutions do not.

Why do I need Server Monitoring?

Software are an essential part of any IT infrastructure. Understanding their outages, uptime, and overall performance helps you better understand and evaluate the performance. Any outages can scare away your new or existing clients, an internal file server malfunction can corrupt important files such as accounts or customer records.

Using a set of specific monitoring tools, you can collect a substantial amount of data that can help your team to understand your project and see it in a bigger picture, with its strong and weak aspects. Normally, you want to monitor the accessibility of your server and how long does it take to reach it (response times). At the same time, you want to keep an eye on any errors or alerts (corrupt files, security breaches, and other issues).

Software Monitoring does not only help in damage control but also prevention - Disk capacity running low? Is your memory or CPU on the verge of collapse during rush hours? Now, you will know about what is happening and what will happen. However, server monitoring is not only about the future and the present but also the past. Thanks to analyzing previously collected data, you can understand your server's performance in time and evaluate it, and discover other anomalies or performance trends.

Server monitoring is a complex process, however you can do it on your own. There are many examples, such as ubuntu's server documentation, that will show you how. However, an open-source, self-hosted solution will not be free. Using a dedicated solution will save you a lot of hassle and can help you deliver a much more reliable service. More importantly, you dedicate your time on things that matter.

What is being monitored?

  • CPU - Understanding the usage of your server's CPU is essential. If its usage peaks way too often and for longer periods, you are looking for trouble
  • RAM - If the server monitor discovers that your server is reaching the memory limit, it is a good time to look for an upgrade or add more RAM
  • Disk Storage - Your system needs enough space; if you run out of space, your system will certainly crash
  • Network - Your server's network performance influences your services' performance greatly.
  • And many more deployment-specific metrics.
