Dstat produces meaning:During performance testing, we generally need to detect many aspects of data, including CPU usage, memory usage, network conditions, load average, process information, disk information, and so on. These data can generally be monitored using commands provided by the system, but in general, these commands are scattered, such as Vmstat,iostat,ss,netstat. But in this way, the command is too scattered, there is an urgent need for a c

kilobytes (KB) Amount of memory used (in kilobytes) Number of packets received per second Number of packets emitted per second Total number of processes How to use ScriptsTo run this script automatically, you need to set up a cron task and set the frequency of the operation according to the actual situation. I find it a good choice to run every five minutes. The script does not need to run as root, so we do not have to assign high permissions to it.If an item in the
