Introduction: Most of the services are running on Linux, Linux is now a very wide range of applications, but there will still be a lot of problems, we will discuss our performance monitoring metrics, performance monitoring is nothing more than I/O, memory, cpu,tcp connection number, network, Process or thread to start,
queue.%UTIL:I/O requests account for the percentage of the CPU, the higher the ratio, the more saturated the description.1. When the value of Avgqu-sz is low, the equipment utilization is higher.2. When the value of%util is close to 1%, it indicates that the device bandwidth is already fullTo determine the system bottleneck, it is sometimes necessary to combine several SAR command options.Suspected CPU bottlenecks, sar-u and sar-q can be used to viewSuspect memory bottlenecks and can be viewed

A few days ago, w3ctech's entry into the famous enterprise-Baidu frontend Fex session once said that he could build his own front-end performance monitoring system seven days after listening to the lecture. Since he said it, he could not give up. In the previous article, the beauty of front-end data I believe everyone has a certain understanding of front-end data. The following describes the
