Ansible 统计服务器资源利用率

ansible playbook，统计服务器 CPU、内存、磁盘利用率，3 条 shell 脚本实现统计

CPU 利用率统计：

top -bn1 | grep load | awk '{printf "CPU Load: %.2f\n", $(NF-2)}'

内存利用率统计：

free -m | awk 'NR==2{printf "Memory Usage: %s/%sMB (%.2f%%)\n", $3,$2,$3*100/$2 }'

磁盘利用率统计（列出每块磁盘利用率）：

df -h -t ext2 -t ext4 | grep -vE '^Filesystem|tmpfs|cdrom' | awk '{ print "Disk Usage:"" " $1 " " $3"/"$2" ""("$5")"}'
