Linux Sysadmin Lab Checklist: Build Skills Without Guesswork

Jul 22, 2026 Mariusz Antonik Automation 6 min read

A Linux sysadmin lab works best when it teaches repeatable operations instead of random commands. Start with a small set of virtual machines, then practice web hosting, users, firewall rules, backups, automation, and linux server monitoring until you can rebuild the environment from notes. This checklist gives developers and small business owners a practical path for learning the skills that make production servers safer.

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.

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.
