Question

我正在编写一个nagios脚本，如果我的任何AWS服务限制即将达到其阈值，它将提醒我。

我现在拥有的：

data = $form.serialize();

并且上述命令的输出为

aws --profile=profile-name support describe-trusted-advisor-check-result --language en --check-id eW7HH0l7J9 --query "result.sort_by(flaggedResources[],&metadata[2])[].metadata" --output text --region us-east-1 | grep Yellow

我想逐行解析输出并收集值：region和service;通知用户相同的内容。

例如，我想通知用户

eu-west-1   VPC Internet gateways   5   4   Yellow
eu-west-1   VPC VPCs    5   4   Yellow

任何建议？

Answer 1

如果我们假设为＆＃34;黄色＆＃34;是你的条件，以下应该做的伎俩。你觉得怎么样？

aws --profile=profile-name support describe-trusted-advisor-check-result --language en --check-id eW7HH0l7J9 --query "result.sort_by(flaggedResources[],&metadata[2])[].metadata" --output text --region us-east-1 | grep Yellow |\
awk -F"\t" '{print "The", $3, "has reached its limit in region", $1}'

Answer 2

使用bash process substitution <()。将以下行放在sample.sh中，设置执行权限chmod +x sample.sh并以bash script.sh

运行脚本

 #!/bin/bash

 while read -r first _ second third _ 
 do
      printf "%s %s %s\n" "The $second $third has reached its limit in region $first"
 done< <(aws --profile=profile-name support describe-trusted-advisor-check-result --language en --check-id eW7HH0l7J9 --query "result.sort_by(flaggedResources[],&metadata[2])[].metadata" --output text --region us-east-1 | grep Yellow)

立即运行脚本，

$ bash script.sh
The Internet gateways has reached its limit in region eu-west-1  
The VPCs 5 has reached its limit in region eu-west-1

在bash中解析变量 - 逐行并将值存储在另一个变量中
