使用 Ansible 统计服务器资源利用率
分享一个 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)}'
1
内存利用率统计：
free -m | awk 'NR==2{printf "Memory Usage: %s/%sMB (%.2f%%)\n", $3,$2,$3*100/$2 }'
1
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
Ansible playbook server-cpu-mem-disk-usage.yml
