Linux system Monitoring Tools Dstat common usage Summary

1) Tool Description
Dstat is a tool for replacing Vmstat,iostat Netstat,nfsstat and Ifstat commands, and is an all-purpose system Information statistic tool. Compared with Sysstat, Dstat has a color interface, which is easy to observe when manually observing performance conditions; and Dstat support instant refresh, such as input Dstat 3, which is collected every three seconds, but the latest data will be refreshed every second. As with Sysstat, Dstat can also collect the specified performance resources.

2) Software Installation

The code is as follows:
# cd/tmp
# RZ
# RPM-UVH dstat-0.6.7-1.el*.rf.noarch.rpm
# which Dstat
/usr/bin/dstat
Or the Ubuntu (Debian system):

The code is as follows:
$ apt-get Install Dstat

-output file is written to the CVS files
This software is similar to Vmstat, but it seems to be less vmstat than the IO part, Dstat only shows the throughput of the disk rather than the load, dstat and almost all monitoring software, You can only monitor the entire system and not analyze a process or a program in depth. The arguments I use often are dstat-cdlmnpsy, alias links aliases dstat= ' Dstat-cdlmnpsy '
