Aug 06, 2026 Mariusz Antonik Automation 6 min read

Disk problems rarely start as dramatic failures; they usually show up first as slow growth, noisy logs, or uneven I/O. Small teams can prevent disk full outages by watching a few practical signals every week instead of waiting for emergency alerts. This guide explains what to check on Linux servers, how to turn those checks into an early-warning habit, and when to clean up or expand storage.

Simple CPU Monitoring on Linux Without Heavy Tools

Aug 04, 2026 Mariusz Antonik Automation 6 min read

Simple CPU monitoring on Linux does not have to start with a large observability stack. For small teams, a weekly snapshot of load average, CPU steal, top processes, and trend direction is often enough to catch pressure before users notice slowdowns. This guide shows a lightweight approach using built-in Linux commands, a small Bash script, and cron-friendly reporting.

Wazuh Agent Enrolled but Missing from Dashboard: A Practical Checklist

Jul 30, 2026 Mariusz Antonik Security 7 min read

When a Wazuh agent says it is enrolled and connected but the dashboard still shows nothing, the problem is often in the gap between transport, identity, and indexed data. A calm checklist keeps teams from reinstalling agents blindly or weakening security controls just to make a host appear. Use this practical linux server monitoring workflow to verify the manager, agent identity, log flow, indexer health, and reporting expectations in the right order.

Bare Metal Linux Server Monitoring Checklist After Leaving the Cloud

Jul 28, 2026 Mariusz Antonik Automation 8 min read

Moving bandwidth-heavy workloads from managed cloud to a dedicated Linux server can cut costs, but it also hands you responsibility for capacity, security, and recovery. The safest first week is not about building a giant observability stack; it is about a practical baseline that catches load, disk, network, service, and lockout problems early. This checklist gives developers and small business owners a friendly starting point for linux server monitoring after a bare-metal migration.

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.
