CPU bottlenecks in Linux rarely happen suddenly—they build over time through gradual performance degradation. This article explains how to identify early warning signs like rising baseline usage and load average changes. You’ll learn practical commands and real-world patterns that signal CPU issues before they impact production. Discover how trend-based monitoring helps you catch problems early and avoid reactive firefighting.

How to Detect Slow Queries in MySQL Before They Cause Problems

How to Detect Slow Queries in MySQL Before They Cause Problems

Slow queries in MySQL rarely announce themselves. They build up quietly over days or weeks, gradually dragging down response times until users start to notice. This guide walks through how to detect slow queries in MySQL using built-in tools like the slow query log and performance_schema. Whether you manage one server or a dozen, this approach gives you actionable visibility without the noise.

How to Track CPU Trend Monitoring on Linux Servers

How to Track CPU Trend Monitoring on Linux Servers

Apr 19, 2026    Mariusz Antonik    Server Health    6 min read

Most monitoring tools tell you when something is already broken, but cpu trend monitoring on Linux is about spotting problems before that moment arrives. By tracking CPU usage history over days and weeks, small infrastructure teams can identify rising load patterns, unexpected overnight spikes, and gradual utilization growth that would never trigger a real-time alert. This guide walks through practical tools including sar, vmstat, and Prometheus to capture and review CPU utilization trends on Linux servers. You will come away with a straightforward approach to weekly health reviews that replaces reactive firefighting with informed capacity planning.

Performance Trend Monitoring for Modern Infrastructure

Performance Trend Monitoring for Modern Infrastructure

Apr 19, 2026    Mariusz Antonik    Infrastructure Monitoring    3 min read

Performance trend monitoring helps you understand how your infrastructure evolves over time instead of reacting to alerts. This approach focuses on identifying gradual changes in CPU, memory, disk, and database performance. By analyzing trends, teams can detect issues early and prevent outages before they happen. It’s a practical method for gaining visibility without adding complexity.

Disk Full Warning on Linux: Catch It Before It Causes Issues

Disk Full Warning on Linux: Catch It Before It Causes Issues

Apr 19, 2026    Mariusz Antonik    Server Health    6 min read

A disk full warning on Linux is easy to ignore until the moment it is not. When a filesystem fills up unexpectedly, it can bring down databases, stop log rotation, and cause application failures that take hours to trace. Understanding how to detect storage issues early, before they tip into real outages, is one of the most practical habits a Linux administrator can build. This guide walks through the common signs, the tools, and the steps to stay ahead of disk saturation on your servers.

Disk space problems tend to build slowly, and by the time a threshold alert fires, the damage is often already done. A bash script for disk monitoring gives you a lightweight, automatic way to check disk usage across your Linux servers on a regular schedule. This guide covers building a working script from scratch, scheduling it with cron, checking inode usage, and making the log output useful over time.

How to Track Disk Space Usage Over Time on a Linux Server

Disk space rarely disappears all at once. On most servers, it fills gradually — a growing log directory here, an expanding database there — until one day the disk is full and something breaks. Tracking disk space usage over time on your Linux server gives you the context to understand how fast your storage is actually growing. With that visibility, you can act weeks ahead of a problem instead of scrambling when a service goes down.
