Linux Performance Tuning Checklist for Small Teams

Jul 18, 2026 Mariusz Antonik Automation 6 min read

Linux performance tuning works best when it starts with the workload, not with random kernel changes copied from a forum. RHEL tuned profiles can help, but small teams still need a safe checklist for choosing a profile, validating the impact, and avoiding changes that hide a capacity problem. This guide shows how to use tuned-adm alongside practical linux server monitoring so performance improvements are measurable and reversible.

Disk forecasting on Linux helps small teams spot storage growth before a server runs out of room. This guide explains how to turn simple usage snapshots into practical capacity planning, warning thresholds, and cleanup decisions. It is written for developers and small business owners who need reliable disk planning without building a large observability program.

Argo CD Repo-Server Exposure Checklist for Small Teams

Jul 16, 2026 Mariusz Antonik Security 7 min read

A repo-server vulnerability in a GitOps platform is not just another patch notice; it is a reminder to verify which internal services can talk to each other. Small teams running Kubernetes need a short checklist for exposure, NetworkPolicies, Redis access, patch status, and follow-up monitoring. This guide turns that concern into practical checks you can run without building a full security operations program.

CPU Performance Decline on a Server: Early Warning Signs for Linux Teams

Jul 15, 2026 Mariusz Antonik Automation 8 min read

A CPU performance decline on a server often starts quietly: load averages creep upward, jobs take longer, and users notice slowness before a hard outage appears. This guide shows small teams how to detect CPU performance degradation on Linux early, separate normal spikes from real saturation, and build a calm weekly review habit. It is written for developers and small business owners who need practical warning signs without running a full observability program.

Source-Built Linux Server Monitoring Checklist for Small Teams

Jul 14, 2026 Mariusz Antonik Automation 7 min read

Source-built Linux systems can be a great fit for teams that want a minimal, auditable server stack, but they also move more operational responsibility onto the maintainer. Without upstream binary mirrors or vendor dashboards, small teams need a simple rhythm for checking builds, packages, logs, disk growth, backups, and security posture. This checklist shows where linux server monitoring matters most when you run a custom or source-built distribution in production.

CentOS FTP to Amazon Linux 2023 Migration Checklist

Jul 12, 2026 Mariusz Antonik Automation 8 min read

Migrating an FTP server from CentOS to Amazon Linux 2023 is more than copying files to a new instance. You need to choose the right daemon, recreate users and permissions carefully, account for SELinux and firewalld differences, and validate transfers before changing DNS or firewall routes. This checklist gives small teams a practical migration path and highlights the linux server monitoring checks that reduce surprises after cutover.

Persistent Linux Remote Desktop Sessions: A Small Business Checklist

Jul 10, 2026 Mariusz Antonik Security 7 min read

Moving from Windows RDP to Linux desktop support is not just a tooling choice. Small teams need persistent GUI sessions, a locked local display, secure access controls, and enough monitoring to know the workstation or jump host remains healthy. This checklist explains the practical options and the operational checks to put in place before relying on remote Linux desktop sessions for daily work.

CPU Monitoring Without Tools: A Practical Linux Guide for Small Teams

Jul 09, 2026 Mariusz Antonik Automation 7 min read

CPU monitoring without tools is useful when you need quick visibility before installing a full observability stack. This guide shows small teams how to inspect CPU pressure with built-in Linux commands, save lightweight snapshots with Bash and cron, and review weekly trends before users feel slowdowns. It also explains when simple checks are enough and when to move toward a managed health-reporting workflow.
