TROUBLESHOOTING

Linux Troubleshooting and System Recovery Services

Linux troubleshooting is a service that diagnoses and resolves server and service interruptions, excessive resource usage, disk I/O blockages, authentication, and network access problems through evidence-based engineering methods, ensuring the system returns to a stable and operational state.

OVERVIEW

What is Linux Troubleshooting and System Recovery Services?

Randomly rebooting a system in a live environment (Production) without evidence collection can lead to loss of logs and concealment of the root cause of the issue.

The process includes: timeline, system logs (journalctl, dmesg, syslog), metrics, running processes (top/htop, ps), memory maps (OOM-Killer), kernel states, and recent configuration changes. Primarily, service accessibility is regained with minimal risk steps; then, root cause analysis (RCA) is conducted to document preventive actions to avoid recurrence.

SERVICE SCOPE

Service scope

01

Diagnosis and Impact Analysis

The start time of the issue, critical services affected, recent system updates, and change logs are determined.

02

Evidence and Metric Collection

Systemd/journalctl logs, kernel dmesg messages, active processes, disk I/O load, network/iptables status, and socket connections are documented.

03

Controlled System Intervention

Data integrity is maintained while the system is brought back to a stable and operational state through minimal risk rollback, configuration fixes, or service configurations.

04

Root Cause Analysis (RCA) and Prevention

The primary and secondary factors triggering the issue are reported; steps for permanent improvement are defined.

WHO IS IT FOR?

Who is it for?

  • Companies experiencing critical Linux service interruptions in live environments (Production).
  • Systems suffering from slowdowns and crashes due to high CPU, RAM overuse (OOM), disk fullness, or I/O bottlenecks.
  • Institutions facing chronic and recurring issues despite internal technical teams failing to identify root causes.
  • Infrastructure with SSH access issues, firewall blockages, or authentication (PAM/sudo) problems.
DELIVERABLES

FREQUENTLY ASKED QUESTIONS

Frequently asked questions

Is a guaranteed solution time provided in emergency situations?

Accessibility and the scope of the issue are evaluated initially. However, a guaranteed solution time or definitive outcome cannot be provided without thorough technical diagnosis and detailed log analysis.

Is a system reboot performed during issue resolution?

Random reboots are not performed. The system can only be rebooted under controlled conditions after assessing data loss risk and business impact, obtaining approval from authorized teams, and collecting live evidence (dump/log).

Is there a risk of recurrence of the Linux issue addressed?

When the root cause is identified and necessary monitoring (monitoring) proactively added, the risk of recurrence is minimized. Hardware issues or external dependencies (e.g., ISP, third-party software) are separately noted as risks in the report.
