linux - 从 linux 机器获取特定的内存和 cpu 值

Question

我有这个脚本:

echo $(date +%F-%H%M ) $( top -n 1 -b -c -p $ZK_PID,$KAFKA_PID,$AGENT_PID,$ENGINE_PID | tail -n 1) >> `hostname`_top.log

产生以下输出:

top - 06:32:15 up 7 days, 21:22,  2 users,  load average: 1.71, 1.66, 1.66
Tasks:   3 total,   0 running,   3 sleeping,   0 stopped,   0 zombie
%Cpu(s): 22.8 us, 15.9 sy,  0.0 ni, 61.1 id,  0.1 wa,  0.0 hi,  0.1 si,  0.0 st

我试图只获取这些进程的 %CPU 和 %MEM 值，我该怎么做？

Answer 1

尝试在你的脚本代码之后添加这个

| grep '%CPU|%MEM'
