Top 10+ Best System Monitoring Software & Tools [2022 Comparison]

It’s virtually impossible to manage today’s complex IT environments at scale without a comprehensive system monitoring solution that allows you to check the health of all your applications and services from a single pane of glass. When your end users are experiencing difficulties, you must have such a tool in place that lets you quickly ascertain and remediate the root cause of the slowdown or error.

In this blog post, we compare some of the best system monitoring software available today, regardless of whether you are looking for a paid, free, or open-source option.

Definition: What Is a System Monitoring Tool?

A system monitoring software is a tool that tracks, logs, and analyzes system resources throughout all layers of the IT environment—from operating systems and firmware at the bottom of the stack, to system applications and services in the middle layer, to user software running at the top.

It collects diverse layer-specific metrics and events using agents, as well as API integrations with third-party tools and services. The software then aggregates and analyzes the metrics and events to give you a correlated holistic view of system health, performance, and security. Once a baseline has been established, the tool alerts admins to anomalous behavior that may have a negative impact on system availability, performance, or security.

What Is the Best System Monitoring Tool for You?

Here are some of the minimum requirements you should look for when choosing a system monitoring software:

  • Support for complex environments: Your system monitoring tool must be able to monitor highly distributed applications, ephemeral components, and diverse hosts and devices across multiple public and private clouds and networks.
  • Centralized management of metrics and insights: You need a reliable and easy-to-parse picture of system health, performance, and integrity. AI-powered analytics and strong visualizations in a consolidated dashboard can give you this.
  • Notifications and alerts: The solution you choose must be able to detect anomalous system behavior anywhere in the stack that is, or could be, detrimental to system performance. It should also be able to notify the right personnel in real time.
  • High levels of automation: Your system monitoring tool should be able to automatically open tickets with detailed information on system activities that led to a detected issue, as well as trigger automated workflows that mitigate, or even fix, the problem, such as shutting down a compromised service or deploying a patch. It should also be able to carry out preventive maintenance with little or no human intervention.
  • Scalability and flexible pricing: Your solution should make it easy for you to scale up or down in response to dynamic system requirements—and to adjust pricing accordingly.
  • Reporting: To help with budget and capacity planning, as well as compliance auditing, choose a tool that comes with a set of informative historical and real-time reports. Since every system is different, these reports should be customizable.

Conclusion

Today’s complex IT environments consist of intertwined layers of infrastructure and firmware, applications and services, and user software. Each layer generates its own metrics, which makes it critical to have good system monitoring tools, such as Sematext, in place. That way, everybody wins. Customers, employees, and partners will enjoy high-performing and always-available apps; DevOps will be able to debug and remediate system performance issues quickly and efficiently; security will rest easy knowing that all system assets and their dependencies are visible and properly configured, and lines of business will get maximum ROI on their products and services.
