Linux System performance Detection tools

Sneak through the site and see some good Linux performance testing tools. Worry about forgetting to make a record here. If there is a wrong place, or insufficient, and usually do not use much, but the force of the tool also please see this blog post of comrades to make a lot of suggestions. Thank you!

Dstat Tools

Description: Dastat This software is dainty, package size is only 144k, installation size 660k.
This tool dynamically displays----total-cpu-usage-----dsk/total--net/total----Paging-----system--load situation by default. (Look at my picture.)

3. How to use

Common parameters

-C CPU is also, display CPU system occupation, user occupation, Idle, wait, interrupt, software interrupt and other information

-C when there is more than one CPU, this parameter can display the CPU state separately on demand

E.g-c 0,1 display cpu0 and CPU1 information

-D disk is also, displays the disks read and write data size

-D HDA and Total

-N NET Display network status

When n-Net has multiple NICs, specify the network card to display

-L load average displays system load conditions

-M memory shows the usage of RAM

-G page display usage of pages

-P process to show the status of processes

-S swap shows swap partition usage

-S similar to d/n

-R I/O request condition

-Y System Status

--IPC Display IPC Message queue, signal, etc. information

--socket used to display TCP UDP port status

-A All this is the default option equivalent to-cdngy

-V Vmstat equivalent to-pmgdsc-d total

--output files This option is also useful for redirecting status information to the specified file in CSV format for later viewing. e.g Dstat--output/root/dstat.csv & Now let the program silently run in the background and output the results to the/root/dstat.csv file
