Clonezilla LUKS2 Backup Repositories: A Weekly Capacity Checklist

Nov 12, 2026 Mariusz Antonik Automation 10 min read

Encrypted image repositories make bare-metal recovery safer, but encryption does not protect them from capacity drift, failed mounts, or incomplete retention. This practical checklist shows how to monitor LUKS2-backed Clonezilla storage, estimate growth, verify usable backups, and preserve recovery headroom. It also covers HTTP Boot infrastructure and the operational checks that matter after a deployment-tool upgrade. Use it as a focused Linux server monitoring routine for imaging environments without adding another dashboard.

CPU Bottleneck Reporting on Linux: Detect Degradation Early

Nov 11, 2026 Mariusz Antonik Automation 8 min read

CPU bottleneck reporting on Linux should explain sustained pressure, not merely list a high utilization percentage. Combining CPU time, run-queue demand, load, process data, and workload context helps teams distinguish real saturation from harmless bursts. This guide shows how to build a concise report that detects degradation early and ends with a practical next action.

Disk Growth Warning Signs: A Weekly Linux Server Checklist

Nov 10, 2026 Mariusz Antonik Automation 9 min read

Disk incidents rarely begin with a completely full filesystem; they begin with a trend that nobody reviews. This weekly Linux server checklist shows how to check capacity, inode use, log growth, deleted-open files, and high-I/O processes before they cause downtime. It also explains which warning signs need immediate action and which belong in a measured cleanup plan. Use it as a lightweight Linux server monitoring routine for small fleets without adding another dashboard.

Is Your First Technical Support Job a Dead End? A Linux-to-DevOps Growth Checklist

Nov 06, 2026 Mariusz Antonik Automation 9 min read

A first technical support job does not have to match your final career goal to be useful. Monitoring servers, maintaining databases, documenting incidents, and administering software can become credible Linux and DevOps experience when you deliberately build depth and evidence. This checklist helps you judge whether the role is still teaching you, identify warning signs, and create a practical 90-day growth plan. It also explains how to turn Linux server monitoring work into portfolio and interview material without exaggerating your responsibilities.

Small Business Server Monitoring: A Practical Weekly Plan

Nov 05, 2026 Mariusz Antonik Automation 8 min read

Small business server monitoring does not need a crowded dashboard or a full-time operations team. A focused weekly review can reveal availability, capacity, storage, backup, database, and security risks while there is still time to act. This guide explains which signals matter, how to set useful thresholds, and how to turn the results into a short action plan.

How Long Should You Keep an Old Linux Server? A Decommissioning Checklist

Nov 04, 2026 Mariusz Antonik Automation 8 min read

Keeping a retired server indefinitely feels safe, but it often preserves uncertainty rather than reducing risk. A short, evidence-based rollback window is usually more useful than a machine gathering dust for years. This checklist covers migration validation, Linux server monitoring, data sanitization, resale, recycling, and the records a small business should retain. It also provides a practical timetable for deciding when old hardware can leave the building.

CPU Monitoring Commands in Linux: A Practical Guide Without Heavy Tools

Nov 03, 2026 Mariusz Antonik Automation 9 min read

Linux includes enough CPU monitoring commands to diagnose most small-server slowdowns without installing a large observability stack. This guide shows how to read load, utilization, process, wait, and pressure signals with uptime, top, ps, vmstat, mpstat, pidstat, and /proc/stat. It also provides a lightweight Bash sampling pattern and a weekly review workflow for spotting sustained CPU pressure early.

Struggling With LPIC-1? A Practical Linux Study and Home Lab Checklist

Nov 02, 2026 Mariusz Antonik Automation 10 min read

Passing simple labs but struggling on a Linux exam usually points to a gap between recognition and recall, not a lack of ability. This checklist turns LPIC-1 or Linux+ objectives into short command-line drills, troubleshooting scenarios, and home-lab evidence. It also shows how Linux server monitoring can make practice measurable instead of random.

From Linux and Cloud Administrator to DevOps Engineer: Resume Evidence Checklist

Oct 31, 2026 Mariusz Antonik Automation 9 min read

A strong DevOps resume does more than list Linux, cloud, and automation tools; it shows how you improved delivery, reliability, and operational feedback. This checklist helps Linux and cloud administrators turn routine work into credible evidence across infrastructure as code, CI/CD, incident response, and Linux server monitoring. It also identifies practical portfolio gaps to close before applying.

Linux Monitoring Script: A Practical Lightweight Server Health Check

Oct 30, 2026 Mariusz Antonik Automation 8 min read

A Linux monitoring script can collect a focused set of server health signals without adding a large monitoring platform. This guide shows how to check load, memory, storage, services, ports, and recent failures while keeping output useful and safe. It includes a practical Bash example plus scheduling, retention, and threshold guidance. Use it as a starting point for lightweight Linux monitoring and weekly infrastructure reviews.
