Performance Testing Tool Dstat

The DSTAT command collects system information such as CPU, disk, NET, system, memory, process and so on, the function is stronger than Vmstat, one command can integrate uptime, Vmstat, top and other related information;

Install dstat command: Yum install-y dstat

Execute the dstat command to collect data from-cpu-、-disk-、-net-,-paging-、-system-by default, once a second. The default input dstat equals input dstat-cdngy 1 or dstat-a 1;

If we execute the dstat 5 command, he collects the information every 5 seconds.

The same dstat can also collect specified performance resources. You can see the corresponding parameters using Dstat-h.
