1.命令行输入top回车，然后按下大写M按照memory排序，按下大写P按照CPU排序。
2. ps -ef | grep "进程名"
ps -e -o 'pid,comm,args,pcpu,rsz,vsz,stime,user,uid' | grep 进程名
例如:
# ps -ef | grep mongodb | grep -v grep
root 18512 1 8 Feb28 ? 11:25:23 mongod -f mongodb.conf
# ps -e -o 'pid,comm,args,pcpu,rsz,vsz,stime,user,uid' | grep 18512 | grep -v grep
18512 mongodmongod -f mongodb.conf 8.0 6243952 7924496 Feb28 root 0
备注:
pid：进程的ID
vsz：进程占用的虚拟内存
rsz：进程占用的物理内存
3. top -d 1 -p pid
例如:
# top -d 1 -p 18512
