10 Best Infrastructure Monitoring Tools in 2025

Infrastructure monitoring gives you insight into the overall health of your project. By collecting and analyzing data coming from IT infrastructure, systems, and processes, you can prevent incidents, evaluate performance, better optimize and scale, or find a root cause of everything that's happening within your system.

The world is becoming more digital every day. This puts a lot of stress on service providers since the performance of their infrastructure is mission-critical for countless clients or end-users. Even small misconfiguration errors or DNS outages can cut people from communicating with the outside world, source of income, or cause other issues.

Infrastructure monitoring ensures that we prevent these major outages, or in the worst-case scenarios reduce the time necessary for a resolution to a minimum.

Benefits of Infrastructure monitoring

Having a good infrastructure monitoring solution allows:

Project performance optimization
Enhancement of the user experience
Capacity to ingest data from a wide array of sources and handle it during both planned and unplanned traffic overloads
Monitoring of detecting and reporting outages, bad resource management, and performance decrease trends over time
Using collected data to determine the root cause
Proactive monitoring, which helps to prevent issues before they occur

What to monitor with Infrastructure monitoring?

Hardware. Collect and analyze data from sensors, such as battery life, CPU and Memory usage, Disk space, fan speed, or user-defined custom sensors.
Network. Make sure that your internal network is performing as it is supposed to. IT infrastructure monitors often offer network monitoring solutions useful not only for performance evaluation but also security.
Applications. Tracking application performance and user behavior is essential for good infrastructure monitoring.

Best Practices in Infrastructure Monitoring

Organize your notifications and alerts. Infrastructure generates enormous amounts of data each day, and not all logs are essential for monitoring. By attributing importance to specific types of notifications, setting thresholds and custom rules, you will receive notifications and alerts in a logical manner, which will be beneficial in incident resolution.
Monitor Baseline Metrics and KPIs. No matter how accurate, your thresholds and alerts are not permanent because your system changes over time due to both internal and external factors. A systemic review of these values will ensure consistent and accurate results.
Pick your partner wisely. The market is saturated with professional and progressive monitoring solutions, and in order to survive, each needs to stand out a bit in their respective fields. You can use this to your advantage, study and compare each solution closely and pick the one that will suit you the most. If they offer a free solution or a trial period, don't hesitate and go for it.
Make sure your teams get the right data. Infrastructure monitoring can produce a lot of operationally valuable data. However, not every team can work with the same data equally. Customize data visualization and dashboards for each team individually.
