Ubuntu 或 Centos 中的 prstat

Question

正如 Java 表现 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.

Centos 或 Ubuntu 中是否有可用的工具，如 prstat？

Answer 1

Linux 中没有 prstat "equivalent" 工具。您可以结合使用 top 和 ps（或 /proc/$pid/ 资源）来获得一些有用的结果；也许编写一个 shell 脚本（使用 grep、sed 和 awk）来收集上述命令和文件的结果。仅供参考，我发现这个 link 关于顶级命令和内核、用户和空闲 CPU 利用率有趣

希望这个帮助ps。

Answer 2

我相信您正在寻找的 Linux 命令是 top 和 pstree 。

这是 ptree 用于 Linux,

#!/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 both

PATH=/bin:/usr/bin:/usr/sbin:/sbin
export PATH

psopt="-e"
case  in
[a-z]*) psopt="-u ";shift;;
esac

[ -z "" ] &&
exec ps $psopt -Ho pid=,args=

#some effort to add less to the ps list
tmp=/tmp/ptree.$$
trap 'rm $tmp' 0 HUP INT TERM
ps $psopt -Ho pid=,args= >$tmp
<$tmp awk '
{ ci=index(substr([=10=],7),); o[ci]=[=10=] }
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=""
