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

In addition, 1. view the error message errpt in the operating system. 2. Use DF to view disk space usage. Here we mainl

The purpose of this article is to let you know how to understand the health of the mongdb you are running. Mongostat detailed Mongostat is a mongdb state detection tool that is used at the command line. It takes a fixed time to get the current running state of the MongoDB and outputs it. If you find that the database suddenly slows down or has other problems, your first-hand actions consider using Mongostat to view the status of the MONGO. Its ou

IntroductionMost of the IO statistics tools under Linux, such as Iostat, Nmon, and so on, are only counted to the Per Device's read and write situations, and if you want to know how each process uses IO, it's a bit cumbersome.Iotop is a top class tool used to monitor disk I/O usage. Iotop has a UI similar to top, which includes information about PID, user, I/O, process, and so on.ExampleJust run it straight.IotopThe output is as followsTotal DISK READ:6.01 m/s | Total DISK WRITE:3.85 k/s TID PRI
