修改配置文件/etc/systemd/system.conf

DefaultCPUAccounting=yes
DefaultMemoryAccounting=yes
DefaultTasksAccounting=yes

重启机器

reboot

统计内存资源消耗，执行完成后再当前目录下生成个log文件

# systemctl | grep service | grep runn | awk  -F " "  '{print$1}' > list

# for  v  in `cat list`
do
    echo " $v `systemctl status  $v | grep Memory `" >> log
done

结果如下：

# cat log
