查看linux启动的线程信息

1、某一进程所有的线程个数、启动时间

ps max -o lstart,lwp,pid,nlwp,cmd|more

lstart： STARTED time the command started.

nlwp： NLWP number of lwps (threads) in the process. (alias thcount).

lwp： LWP lwp (light weight process, or thread) ID of the lwp being reported.

2、Java进程信息查看

jstack <pid>|grep <desc>|cut -c<startindex>-<endindex>|sort |uniq -c

例如：jstack 12041|grep job|cut -c0-43|sort |uniq -c

3、查看进程创建的线程信息

top -p <pid> -H
