No resource bottlenecks are slowing things down.The server resources are sufficient for mission-critical applications and services to work at peak performance.Specifically, you use Linux system monitoring programs to ensure that: The Linux system monitor tools accomplish this by gathering data on each server’s key performance indicators (KPIs), network connectivity, and application availability. They set a goal of ensuring that a server is performing optimally, they provide information that lets Linux administrators understand what’s going on, and sometimes automate their responses to those situations. Once you’ve mastered these dedicated applications – most of which are built into the operating system – you’ll be well on your way to Linux system administrator expertise.Īll server monitoring programs have a few things in common. Linux system monitoring tools reassure you when things are working right, and help you recognize odd behavior, performance anomalies, and their source when the server misbehaves. The only way to know that your Linux-server-based applications and services are running well is to measure what’s going on in the server and its connectivity status.
