10 Best Server Performance Monitoring Tools & Software in 2023

Setting up and administering multiple servers for business and application purposes has become easier thanks to advancements in cloud technology. Today, enterprises are choosing to operate large numbers of servers both in the cloud and in their data centers to meet the ever-increasing demand. As a result of these changes, monitoring technologies have become crucial.

In this post, we’ll explore the best server monitoring tools and software currently on the market. We’ll also discuss how to choose the right monitoring tool for you.

What Is a Server Monitoring Software?

Server performance monitoring is the process of tracking the performance of how your server resources are being utilized by collecting and analyzing metrics. This is where monitoring software comes into play—it makes sure your applications run smoothly and that your servers have enough resources available to run their processes. This means it monitors certain key server components:

  • CPU: The percentage of CPU utilization should ideally be peaking to its maximum only rarely, and the peaks should be short. If the CPU is maxed out frequently or very close to the max even during non-peak periods, it’s a sign the system doesn’t have much headroom.
  • Used memory: If this indicator is reaching your memory limit, you might want to think about horizontally scaling your servers or adding more RAM.
  • Storage: Being aware of disk storage utilization is crucial in production systems—if the disks run out of space, system crashes will ensue.
  • Network: By monitoring network bandwidth and throughput, you can see how traffic is being delivered to your server.

Best Monitoring Tools for Servers

While there are many types of server management software, each one focuses on a different area of monitoring. In this section, we’ll discuss some of the best server monitoring tools and their standout features.

Which Is the Best Server Monitoring Tool for You

There are plenty of server performance monitoring tools available on the market—both open-source and SaaS models. At the end of the day, they all get the job done. Choosing the right one depends on your organization’s requirements and the resources—effort and money—you have to invest. Below are a few key areas to keep in mind when choosing an enterprise monitoring solution.

Metric Coverage

This is a no-brainer. Your monitoring solution needs to be able to collect and analyze all the metrics that are important to you. Some tools only support a few metrics, and some support a large number of metrics that you don’t really need. You also have to be able to configure the metrics you do need and customize them to match your requirements.

Less Configuration Overhead

While DIY tools sound exciting and fun, they can be frustrating when things don’t work out. For an enterprise monitoring solution, you need to look for a solution that is easy to set up, requires less maintenance, and has most of your needs covered via its default settings for alerts and dashboards.

Correlation of Metrics

Even if a tool supports all the metrics you need, it is cumbersome if there is no correlation between them, especially when debugging a problem. Having proper correlation between metrics can save you a lot of time and help you drill down to the root cause of your problem within minutes.

Anomaly Detection

Sometimes, it is not really feasible to give a static threshold for a given metric to fire an alert. Sometimes, you might not even know an alert is needed until something goes wrong. Tools with anomaly detection capabilities, integrated with machine learning and artificial intelligence, will automate and configure most alerts for you.

Identity Federation and Access Control

Enterprises often have teams dedicated to observability. User access management and fine-tuned access control are required to run a tight ship. Most enterprises have their own identity management tools with SSO functionality, and it is very important for the solution you select to support those tools either via LDAP or SAML.

Total Cost of Ownership

SaaS solutions for monitoring have become widely popular today, as managing and maintaining enterprise-level monitoring platforms by yourself on-premises can be very costly and time-consuming—not to mention the complexities of DIY monitoring to make sure your platform is running as expected. It is best to offload your monitoring to a SaaS and take the complexity and operational overhead away.

Real-time server monitoring is required to keep your applications running smoothly. A comprehensive understanding of your server’s status and its effect on your architecture is essential. In fact, operating an in-house monitoring system is expensive and has a high operational overhead that is frequently underestimated. Monitoring using a SaaS solution allows for cost savings and operational compliance. With quicker debugging, you can prevent revenue loss due to a severe bug or performance problem affecting your commercial services.

Of all the server performance tools discussed in this article, Sematext is an all-around winner for any enterprise monitoring needs—whether for on-premises or multi-cloud servers.
