Shell script to display - Memory usage, Disk Usage and CPU Load?
提问by AKIWEB
I want to diplay the Memory usage, Disk Usage and CPU Load in the following format:
我想以以下格式显示内存使用情况、磁盘使用情况和 CPU 负载：
Memory Usage: 33/512MB (6%)
Disk usage: 4.2/20GB (23%)
CPU Load: 0.01
So I started using the below script to do that but somehow it gives me an error
所以我开始使用下面的脚本来做到这一点，但不知何故它给了我一个错误
#!/bin/bash
free -m | awk 'NR==2{printf "Memory Usage: %s/%sMB (%.2f%)\n", ,,*100/ }'
df -h | awk '$NF=="/"{printf "Disk Usage: %d/%dGB (%s)\n", ,,}'
top -bn1 | grep load | awk '{printf "CPU Load: %.2f\n", $(NF-2)}'
Below is the error I get -
以下是我得到的错误 -
awk: run time error: not enough arguments passed to printf("Memory Usage: %s/%sMB (%.2f%)
")
FILENAME="-" FNR=2 NR=2
I am running ubuntu 12.04. Any idea what's wrong?
我正在运行 ubuntu 12.04。知道出了什么问题吗？
Update:-
更新：-
After running my below shell script -
运行我下面的 shell 脚本后 -
#!/bin/bash
free -m | awk 'NR==2{printf "Memory Usage: %s/%sMB (%.2f%%)\n", ,,*100/ }'
df -h | awk '$NF=="/"{printf "Disk Usage: %d/%dGB (%s)\n", ,,}'
top -bn1 | grep load | awk '{printf "CPU Load: %.2f\n", $(NF-2)}'
I got below output -
我低于输出 -
Memory Usage: 128504/128896MB (99.70%)
Disk Usage: 3/48GB (8%)
CPU Load: 0.40
Does CPU Load looks ok? What does 0.40 means? And what number I should say will be high for CPU Load?
CPU 负载看起来正常吗？0.40 是什么意思？我应该说哪个数字对 CPU 负载来说会很高？

Try escaping the %:
尝试转义%：
printf "Memory Usage: %s/%sMB (%.2f%%)\n"
