System Health & Performance Management

Implemented ongoing monitoring and performance optimization for Linux servers, ensuring reliability, uptime, and operational efficiency for business-critical systems.

01. OVERVIEW

Enterprise systems require continuous monitoring to prevent downtime and maintain performance. This project focused on analyzing resource usage, verifying service availability, assessing disk and network health, and maintaining overall system integrity for production Linux servers. These procedures reflect real-world operational maintenance and performance management tasks.

02. METHODOLOGY

  • Resource Monitoring: Tracked CPU, memory, and process behavior using top, htop, vmstat, and free -h to prevent performance bottlenecks.
  • Disk & Filesystem Management: Checked disk utilization, health, and storage efficiency with df -h, du -sh, lsblk, and smartctl.
  • Service & Daemon Oversight: Ensured critical services ran reliably via systemctl, journalctl, and log review, minimizing downtime for business operations.
  • Network Health Management: Monitored connectivity, latency, and routing with ping, ss, netstat, and traceroute to ensure smooth network operation.
  • Security & System Integrity: Maintained proper permissions, user accounts, process monitoring, and updates with ps aux, sudoers, and package managers to protect production servers.
