如何迭代匹配模式的循环并使用awk打印计数

Question

我有以下的多路径输出。

mig_1 (3624a9370908ba6a5e68a464600014087) dm-11 PURE,FlashArray
size=5.0T features='0' hwhandler='0' wp=rw
`-+- policy='queue-length 0' prio=1 status=active
  |- 0:0:2:3 sdeo 129:0  active ready running
  |- 0:0:3:3 sdep 129:16 active ready running
  |- 1:0:2:3 sdeq 129:32 active ready running
  `- 1:0:3:3 sder 129:48 active ready running
mig_2 (3624a9370908eb6a5f69a4646000140bb) dm-10 PURE,FlashArray
size=7.0T features='0' hwhandler='0' wp=rw
`-+- policy='queue-length 0' prio=1 status=active
  |- 0:0:2:2 sdkg 66:320 active ready running
  |- 0:0:3:2 sdkh 66:336 active ready running
  |- 1:0:2:2 sdki 66:352 active ready running
  `- 1:0:3:2 sdkj 66:368 active ready running

要检查每个LUN存在多少活动路径。如果LUN没有准备好运行/active /它应该减少计数。尝试了下面的方法，但它没有提供所需的结果。它提供了所有的伦的总数，也是大小是不同的线。

 cat multi | awk '/dm-1/ {print $1"\t"$2} ; /^size/ {print $1} ; /active ready running/ {a++} END {print a}'
mig_1   (3624a9370908ba6a5e68a464600014087)
size=5.0T
mig_2   (3624a9370908eb6a5f69a4646000140bb)
size=7.0T
8

预期产出如下：

Disk  #1:  mig_1  (3624a9370908ba6a5e68a464600014087)  size=5.0T  active_paths:4
Disk  #2:  mig_2  (3624a9370908eb6a5f69a4646000140bb)  size=7.0T  active_paths:4

请提供如何实现上述输出的建议。

Answer 1

对于所显示的示例(仅)，请尝试遵循awk代码。在GNU awk中编写和测试，应该可以在任何awk版本中工作。

awk '
/^mig_[0-9]+/{
  if(found && val1 && val2 && count){
    print "Disk  #" ++count2,val1,val2,"active_paths:"count
    count=val1=val2=found=""
  }
  val1=$1 OFS $2
  found=1
  next
}
found && /^size=[0-9]+/{
  val2=$1
  next
}
found && /active ready running/{
  count++
}
END{
  if(found && val1 && val2 && count){
    print "Disk  #" ++count2,val1,val2,"active_paths:"count
  }
}
'   Input_file

站在巨人的肩膀上，我的回答是基于@RavinderSingh13的回答。我在评论中指出，除了是伟大的awk代码之外，它不会为没有活动路径的设备打印一行，从而丢失所有路径向下的设备。作为超过5年的存储支持工程师和略多于两年的存储管理员，我第一手地知道，拥有一行"0“活动路径可能是最关键的。因此，我修改了RavinderSingh13的awk来解释这一点。我还剪掉了一些不必要的碎片。

awk '
/^mig_[0-9]+/{
  if(found){
    if(!active){
      active="ALL PATHS DOWN"
    }
    print "Disk  #" ++count,val1,val2,"active_paths:"active
    active=val1=val2=""
  }
  else{
    found=1
  }
  val1=$1 OFS $2
  next
}
/^size=[0-9]+/{
  val2=$1
  next
}
/active ready running/{
  active++
}
END{
  if(!active){
    active="ALL PATHS DOWN"
  }
  print "Disk  #" ++count,val1,val2,"active_paths:"active
}
' mpath.txt

mpath.txt (请注意，我无法访问具有多路径设备的SAN或服务器，更不用说具有非活动/健康路径的SAN或服务器，因此我将输出“失败的错误停止”--不管怎么说，这些任意字符串对我的awk代码修改没有影响-它将在输出中的任何路径行上工作，而这些路径线不是严格的“活动就绪运行”)。

我希望我的修改是受欢迎的，我希望RavinderSingh13得到98%的信贷。
