Server Monitoring
Server monitoring is the practice of continuously tracking the performance, health, and availability of servers (physical, virtual, or cloud-based) to ensure optimal operation and prevent downtime. It involves collecting metrics like CPU usage, memory consumption, disk I/O, network traffic, and application response times, often using specialized software or platforms. This enables IT teams to detect issues proactively, troubleshoot problems, and maintain service reliability.
Developers should learn server monitoring to ensure application stability, performance optimization, and rapid incident response in production environments. It is essential for DevOps, SRE (Site Reliability Engineering), and backend roles where maintaining uptime and meeting SLAs (Service Level Agreements) is critical. Use cases include monitoring web servers, databases, microservices, and cloud infrastructure to prevent outages and improve user experience.
