linux – 在Ubuntu或Centos中的prstat

概述正如 Java Performance所说： Solaris prstat has additional capabilities such as reporting both user and kernel or system CPU utilization along with other microstate information using the prstat -m and -L op 正如 Java Performance所说：

Solaris prstat has additional capabilitIEs
such as reporting both user and kernel or system cpu utilization along with other
microstate information using the prstat -m and -L options. The -m option prints
microstate information,and -L prints statistics on per lightweight process.

在Centos或Ubuntu中有没有像prstat这样的工具？

解决方法 我相信你正在寻找的 Linux命令是top和pstree.

这是linux的ptree,

#!/bin/sh# Solaris style ptree[ -x /usr/bin/ptree ] && exec /usr/bin/ptree "$@"# Print process tree#  = PID : extract tree for this process#  = user : filter for this (existing) user#  = user  = PID : do bothPATH=/bin:/usr/bin:/usr/sbin:/sbinexport PATHpsopt="-e"case  in[a-z]*) psopt="-u ";shift;;esac[ -z "" ] &&exec ps $psopt -Ho pID=,args=#some effort to add less to the ps Listtmp=/tmp/ptree.$$trap 'rm $tmp' 0 HUP INT TERMps $psopt -Ho pID=,args= >$tmp<$tmp awk '{ ci=index(substr(,7),); o[ci]= }ci>s[a] { s[++a]=ci }==pID {    for(i=1;i<=a;i++) {            si=s[i]; if(si<=ci) print o[si]    }    walkdown=ci            next}ci<walkdown { exit }walkdown!=0 { print }' pID=""
