Dstat monitoring under Linux

Dstat
If the system does not have some tools yum-y install Dstat installation is complete, this software is small, package size is only 144k, installation size 660k.
This tool will dynamically display the Cpu,disk,net,page,system load situation by default, as shown below, of course there will be different colors marked, or more intuitive, for the moment the direct copy make a look, but also hope you crossing Haihan, never shoot bricks.

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

1. CPU:hiq,Siq are hard interrupt and soft interrupt number respectively.

2. System:int,CSW is the number of interrupts (interrupt) and Context switches ( Context Switch)
